From b97b6c73b8ed077ace725691b18b5e57d3fbda85 Mon Sep 17 00:00:00 2001 From: John Safranek Date: Thu, 21 Dec 2023 12:05:15 -0800 Subject: [PATCH 001/173] RSA Verify 1. Added function wolfSSH_RsaVerify() which verifies the provided RSA signature with the provided key. 2. Call wolfSSH_RsaVerify() after all calls to wc_RsaSSL_Sign(). 3. Changed a comparison between an unsigned and 0 to == from <=. 4. Fixed a spot where we still tried to sign a digest when the call to wc_DigestFinal() failed. --- src/agent.c | 4 +++ src/internal.c | 89 ++++++++++++++++++++++++++++++++++++++-------- wolfssh/internal.h | 4 +++ 3 files changed, 82 insertions(+), 15 deletions(-) diff --git a/src/agent.c b/src/agent.c index f72b7185e..78fc73c06 100644 --- a/src/agent.c +++ b/src/agent.c @@ -701,6 +701,10 @@ static int SignHashRsa(WOLFSSH_AGENT_KEY_RSA* rawKey, enum wc_HashType hashType, WLOG(WS_LOG_DEBUG, "Bad RSA Sign"); ret = WS_RSA_E; } + else { + ret = wolfSSH_RsaVerify(sig, *sigSz, + encSig, encSigSz, &key, heap, "SignHashRsa"); + } } wc_FreeRsaKey(&key); diff --git a/src/internal.c b/src/internal.c index c68e136c0..7e9727cf6 100644 --- a/src/internal.c +++ b/src/internal.c @@ -9422,6 +9422,47 @@ static INLINE byte SigTypeForId(byte id) } +#ifndef WOLFSSH_NO_RSA +/* + * wolfSSH_RsaVerify + * sig - signature to verify + * sigSz - signature to verify size + * digest - encoded digest for verification + * digestSz - encoded digest size + * key - key used to sign and verify signature + * heap - allocation heap + * loc - calling function for logging + */ +int wolfSSH_RsaVerify(byte *sig, word32 sigSz, + const byte* digest, word32 digestSz, + RsaKey* key, void* heap, const char* loc) +{ + byte* checkSig; + int ret = WS_SUCCESS; + + checkSig = (byte*)WMALLOC(sigSz, heap, DYNTYPE_TEMP); + if (checkSig == NULL) { + ret = WS_MEMORY_E; + } + else { + int checkSz; + + checkSz = wc_RsaSSL_VerifyInline(sig, sigSz, &checkSig, key); + if (checkSz < 0 + || (word32)checkSz != digestSz + || WMEMCMP(digest, checkSig, digestSz) != 0) { + WLOG(WS_LOG_DEBUG, "%s: %s", loc, "Bad RSA Sign Verify"); + ret = WS_RSA_E; + } + ForceZero(checkSig, sigSz); + WFREE(checkSig, heap, DYNTYPE_TEMP); + } + + return ret; +} +#endif /* WOLFSSH_NO_RSA */ + + /* SendKexDhReply() * It is also the funciton used for MSGID_KEXECDH_REPLY.

Some whitespace cleanup, and removing a redundant include. --- src/internal.c | 8 +++++++- src/ssh.c | 6 +++++- src/wolfsftp.c | 32 ++++++++++++++++++++++++++------ wolfssh/port.h | 18 +++++++++++++----- 4 files changed, 51 insertions(+), 13 deletions(-) diff --git a/src/internal.c b/src/internal.c index 7e9727cf6..34e27f2f5 100644 --- a/src/internal.c +++ b/src/internal.c @@ -54,7 +54,11 @@ #include #else #define WOLFSSH_MISC_INCLUDED - #include "src/misc.c" + #if defined(WOLFSSL_NUCLEUS) + #include "src/wolfssh_misc.c" + #else + #include "src/misc.c" + #endif #endif @@ -13849,6 +13853,8 @@ int wolfSSH_CleanPath(WOLFSSH* ssh, char* in) if (path[sz - 1] == ':') { path[sz] = WS_DELIM; path[sz + 1] = '\0'; + in[sz] = WS_DELIM; + in[sz + 1] = '\0'; } /* clean up any multiple drive listed i.e. A:/A: */ diff --git a/src/ssh.c b/src/ssh.c index 4e3758d72..a2fe0e91e 100644 --- a/src/ssh.c +++ b/src/ssh.c @@ -39,7 +39,11 @@ #include #else #define WOLFSSH_MISC_INCLUDED - #include "src/misc.c" + #if defined(WOLFSSL_NUCLEUS) + #include "src/wolfssh_misc.c" + #else + #include "src/misc.c" + #endif #endif #ifdef HAVE_FIPS diff --git a/src/wolfsftp.c b/src/wolfsftp.c index e32d09d04..0d62ade4a 100644 --- a/src/wolfsftp.c +++ b/src/wolfsftp.c @@ -34,7 +34,11 @@ #include #else #define WOLFSSH_MISC_INCLUDED - #include "src/misc.c" + #if defined(WOLFSSL_NUCLEUS) + #include "src/wolfssh_misc.c" + #else + #include "src/misc.c" + #endif #endif /* for XGMTIME if defined */ @@ -2731,6 +2735,15 @@ static int wolfSSH_SFTPNAME_readdir(WOLFSSH* ssh, WDIR* dir, WS_SFTPNAME* out, ret = WS_NEXT_ERROR; } + if (special) { + sz = WSTRLEN(out->fName); + + if ((out->fName[sz - 1] == '/') || (out->fName[sz - 1] == WS_DELIM)) { + out->fName[sz - 1] = '\0'; + out->fSz--; + } + } + /* Use attributes and fName to create long name */ if (SFTP_CreateLongName(out) != WS_SUCCESS) { WLOG(WS_LOG_DEBUG, "Error creating long name for %s", out->fName); @@ -4271,12 +4284,22 @@ int SFTP_RemoveHandleNode(WOLFSSH* ssh, byte* handle, word32 handleSz) #ifndef NO_WOLFSSH_MKTIME #define WS_GETDAY(d) ((d) & 0x001f) -#define WS_GETMON(d) (((d) >> 5) & 0x000f) +#define _GETMON(d) (((d) >> 5) & 0x000f) /* number of years since 1900. year + 1980 - 1900 */ #define WS_GETYEAR(d) ((((d) >> 9) & 0x007f) + 80) -#define WS_GETHOUR(t) (((t) >> 11) & 0x001f) +#define _GETHOUR(t) (((t) >> 11) & 0x001f) #define WS_GETMIN(t) (((t) >> 5 ) & 0x003f) #define WS_GETSEC(t) (((t) << 1 ) & 0x003f) +#ifdef WOLFSSL_NUCLEUS + /* mktime() expects month from 0 to 11.

Don't make it conditional on want read as well.

Split ParseAndVerifyCert() into ParseCertChainVerify() and ParseCert() with a common ParseCertChain() function. 2. When the server is checking the user's certificate, don't do the verify step. Verify when the user's client sends a signature. The server needs to tell the client the cert is OK as a cert. Make the client do a PK sign. 3. If the certificate check fails, we still need to be able to send the failure message to the peer. Set the `ret` value back to `WS_SUCCESS`. All other auth actions are gated on the `authFailed`. 4.

In SendKexDhReply(), break down the key agreement actions for the various supported key types into their own functions. Remove the redundant variables. 2. In DoKexDhInit(), add flags for the various key agreement types, and set them as appropriate when checking the selected kexId. The flags are always present no matter the build options. 3. Simplify some of the flag checks for optional options. --- src/internal.c | 752 ++++++++++++++++++++++++++----------------------- 1 file changed, 406 insertions(+), 346 deletions(-) diff --git a/src/internal.c b/src/internal.c index f8c689e79..982b82459 100644 --- a/src/internal.c +++ b/src/internal.c @@ -10046,6 +10046,371 @@ int wolfSSH_RsaVerify(byte *sig, word32 sigSz, #endif /* WOLFSSH_NO_RSA */ +static int KeyAgreeDh_server(WOLFSSH* ssh, byte hashId, byte* f, word32* fSz) +#ifndef WOLFSSH_NO_DH +{ + int ret = WS_SUCCESS;

Add a parameter to the client key agree functions for the hashId. It's only really used for EcdhKyber1, but it keeps the functions parallel. 2. Add and update some top-of-function comments for the key agree functions. 3. Renamed the X25519 key agreement functions to Curve25519 to match the naming in the RFC. 4. Removed the temporary hashId local in the client EcdhKyber1 function. 5. Messed around with some variable declarations in a few of the functions. 6. Fix a couple breaks for small stack build. 7. Fix where GEX-SHA2 key exchange wasn't allowed to work. 8. Disable EcdhKyber1 is ECDH-NISTP256 is disabled. --- src/internal.c | 171 ++++++++++++++++++++++++++++++++------------- wolfssh/internal.h | 6 +- 2 files changed, 127 insertions(+), 50 deletions(-) diff --git a/src/internal.c b/src/internal.c index 982b82459..8dbc1d82c 100644 --- a/src/internal.c +++ b/src/internal.c @@ -4603,14 +4603,19 @@ static void FreePubKey(struct wolfSSH_sigKeyBlock *p) /* KeyAgreeDh_client + * hashId - wolfCrypt hash type ID used * f - peer public key * fSz - peer public key size */ -static int KeyAgreeDh_client(WOLFSSH* ssh, const byte* f, word32 fSz) +static int KeyAgreeDh_client(WOLFSSH* ssh, byte hashId, + const byte* f, word32 fSz) #ifndef WOLFSSH_NO_DH { int ret; + WLOG(WS_LOG_DEBUG, "Entering KeyAgreeDh_client()"); + WOLFSSH_UNUSED(hashId); + PRIVATE_KEY_UNLOCK(); ret = wc_DhAgree(&ssh->handshake->privKey.dh, ssh->k, &ssh->kSz, @@ -4624,11 +4629,14 @@ static int KeyAgreeDh_client(WOLFSSH* ssh, const byte* f, word32 fSz) } ForceZero(ssh->handshake->x, ssh->handshake->xSz); wc_FreeDhKey(&ssh->handshake->privKey.dh); + + WLOG(WS_LOG_DEBUG, "Leaving KeyAgreeDh_client(), ret = %d", ret); return ret; } #else /* WOLFSSH_NO_DH */ { WOLFSSH_UNUSED(ssh); + WOLFSSH_UNUSED(hashId); WOLFSSH_UNUSED(f); WOLFSSH_UNUSED(fSz); return WS_INVALID_ALGO_ID; @@ -4637,10 +4645,12 @@ static int KeyAgreeDh_client(WOLFSSH* ssh, const byte* f, word32 fSz) /* KeyAgreeEcdh_client + * hashId - wolfCrypt hash type ID used * f - peer public key * fSz - peer public key size */ -static int KeyAgreeEcdh_client(WOLFSSH* ssh, const byte* f, word32 fSz) +static int KeyAgreeEcdh_client(WOLFSSH* ssh, byte hashId, + const byte* f, word32 fSz) #ifndef WOLFSSH_NO_ECDH { int ret = WS_SUCCESS; @@ -4648,6 +4658,10 @@ static int KeyAgreeEcdh_client(WOLFSSH* ssh, const byte* f, word32 fSz) #ifndef WOLFSSH_SMALL_STACK ecc_key key_s; #endif + + WLOG(WS_LOG_DEBUG, "Entering KeyAgreeEcdh_client()"); + WOLFSSH_UNUSED(hashId); + #ifdef WOLFSSH_SMALL_STACK key_ptr = (ecc_key*)WMALLOC(sizeof(ecc_key), ssh->ctx->heap, DYNTYPE_PRIVKEY); @@ -4682,11 +4696,14 @@ static int KeyAgreeEcdh_client(WOLFSSH* ssh, const byte* f, word32 fSz) } #endif wc_ecc_free(&ssh->handshake->privKey.ecc); + + WLOG(WS_LOG_DEBUG, "Leaving KeyAgreeEcdh_client(), ret = %d", ret); return ret; } #else /* WOLFSSH_NO_ECDH */ { WOLFSSH_UNUSED(ssh); + WOLFSSH_UNUSED(hashId); WOLFSSH_UNUSED(f); WOLFSSH_UNUSED(fSz); return WS_INVALID_ALGO_ID; @@ -4694,16 +4711,21 @@ static int KeyAgreeEcdh_client(WOLFSSH* ssh, const byte* f, word32 fSz) #endif /* WOLFSSH_NO_ECDH */ -/* KeyAgreeX25519_client +/* KeyAgreeCurve25519_client + * hashId - wolfCrypt hash type ID used * f - peer public key * fSz - peer public key size */ -static int KeyAgreeX25519_client(WOLFSSH* ssh, const byte* f, word32 fSz) +static int KeyAgreeCurve25519_client(WOLFSSH* ssh, byte hashId, + const byte* f, word32 fSz) #ifndef WOLFSSH_NO_CURVE25519_SHA256 { int ret; curve25519_key pub; + WLOG(WS_LOG_DEBUG, "Entering KeyAgreeCurve25519_client()"); + WOLFSSH_UNUSED(hashId); + ret = wc_curve25519_init(&pub); if (ret == 0) { ret = wc_curve25519_check_public(f, fSz, @@ -4731,11 +4753,13 @@ static int KeyAgreeX25519_client(WOLFSSH* ssh, const byte* f, word32 fSz) wc_curve25519_free(&pub); wc_curve25519_free(&ssh->handshake->privKey.curve25519); + WLOG(WS_LOG_DEBUG, "Leaving KeyAgreeCurve25519_client(), ret = %d", ret); return ret; } #else /* WOLFSSH_NO_CURVE25519_SHA256 */ { WOLFSSH_UNUSED(ssh); + WOLFSSH_UNUSED(hashId); WOLFSSH_UNUSED(f); WOLFSSH_UNUSED(fSz); return WS_INVALID_ALGO_ID; @@ -4744,17 +4768,20 @@ static int KeyAgreeX25519_client(WOLFSSH* ssh, const byte* f, word32 fSz) /* KeyAgreeEcdhKyber1_client + * hashId - wolfCrypt hash type ID used * f - peer public key * fSz - peer public key size */ -static int KeyAgreeEcdhKyber1_client(WOLFSSH* ssh, const byte* f, word32 fSz) +static int KeyAgreeEcdhKyber1_client(WOLFSSH* ssh, byte hashId, + const byte* f, word32 fSz) #ifndef WOLFSSH_NO_ECDH_NISTP256_KYBER_LEVEL1_SHA256 { int ret = WS_SUCCESS; - byte hashId = WC_HASH_TYPE_SHA256; byte sharedSecretHashSz = 0; byte *sharedSecretHash = NULL; ecc_key *key_ptr = NULL; + OQS_KEM *kem; + #ifndef WOLFSSH_SMALL_STACK ecc_key key_s; #endif @@ -4767,10 +4794,13 @@ static int KeyAgreeEcdhKyber1_client(WOLFSSH* ssh, const byte* f, word32 fSz) #else /* !

Initialize all the fds to -1. 2. Add flags for peerConnected and stdoutEmpty. 3. Remove the idle counter. 4. When the socket would block on write, set a flag to check the socket for writing later to call the worker which will send pending data. 5. When reading the pipes, a 0 returns means the pipe is closed. Deal with that. 6. If the ssh write fails, interrupt the subordinate process. 7. When waiting for the peer to close its channel and shutdown, sleep for 100ms, rather than 1us. It takes a little while to tear down. 8. Shutdown the peer socket. Spin on receiving the peer socket until it closes or has an error. 9.

For the ASCII and Wide versions of types and functions, make sure the wolfSSHd is being consistent using them. 2. In SFTP, use WSOCKETCLOSE to close the socket. Use the correct type for the socket. 3. Add parens around part of a ternary operator check to clear up some ambiguous order of operations. 4. Add a variable initializer for a COORD structure. 5. Add parameter checks to the Base16_Decode function. 6. Fix a double-freed handle. 7. Clean up a bunch of build warnings. --- apps/wolfsshd/wolfsshd.c | 63 +++++++++++++++++++++------------------- src/wolfsftp.c | 6 ++-- tests/api.c | 5 ++-- tests/sftp.c | 2 ++ wolfssh/test.h | 5 +++- 5 files changed, 45 insertions(+), 36 deletions(-) diff --git a/apps/wolfsshd/wolfsshd.c b/apps/wolfsshd/wolfsshd.c index c2656a914..2b6906212 100644 --- a/apps/wolfsshd/wolfsshd.c +++ b/apps/wolfsshd/wolfsshd.c @@ -151,6 +151,7 @@ static void SyslogCb(enum wolfSSH_LogLevel level, const char *const msgStr) #ifdef _WIN32 static void ServiceDebugCb(enum wolfSSH_LogLevel level, const char* const msgStr) +#ifdef UNICODE { WCHAR* wc; size_t szWord = WSTRLEN(msgStr) + 3; /* + 3 for null terminator and new @@ -170,7 +171,13 @@ static void ServiceDebugCb(enum wolfSSH_LogLevel level, const char* const msgStr } WOLFSSH_UNUSED(level); } +#else +{ + OutputDebugString(msgStr); + WOLFSSH_UNUSED(level); +} #endif +#endif /* _WIN32 */ static void ShowUsage(void) { @@ -674,7 +681,6 @@ static int SFTP_Subsystem(WOLFSSHD_CONNECTION* conn, WOLFSSH* ssh, } if (ret == WS_SUCCESS) { - r[rSz] = '\0'; wolfSSH_Log(WS_LOG_INFO, "[SSHD] Using directory %s for SFTP connection", r); if (wolfSSH_SFTP_SetDefaultPath(ssh, r) != WS_SUCCESS) { @@ -832,7 +838,6 @@ static int SHELL_Subsystem(WOLFSSHD_CONNECTION* conn, WOLFSSH* ssh, /* @TODO check for conpty support LoadLibrary()and GetProcAddress(). */ - if (forcedCmd != NULL && WSTRCMP(forcedCmd, "internal-sftp") == 0) { wolfSSH_Log(WS_LOG_ERROR, "[SSHD] Only SFTP connections allowed for user " @@ -912,6 +917,7 @@ static int SHELL_Subsystem(WOLFSSHD_CONNECTION* conn, WOLFSSH* ssh, if (ret == WS_SUCCESS) { SECURITY_ATTRIBUTES saAttr; + ZeroMemory(&saAttr, sizeof(saAttr)); saAttr.nLength = sizeof(SECURITY_ATTRIBUTES); saAttr.bInheritHandle = TRUE; saAttr.lpSecurityDescriptor = NULL; @@ -926,28 +932,30 @@ static int SHELL_Subsystem(WOLFSSHD_CONNECTION* conn, WOLFSSH* ssh, } if (ret == WS_SUCCESS) { - STARTUPINFO si; + STARTUPINFOW si; PCWSTR conCmd = L"wolfsshd.exe -r "; PWSTR conCmdPtr; - int conCmdSz; + size_t conCmdSz; SetHandleInformation(ptyIn, HANDLE_FLAG_INHERIT, 0); SetHandleInformation(ptyOut, HANDLE_FLAG_INHERIT, 0); wolfSSH_SetTerminalResizeCtx(ssh, (void*)&ptyIn); - conCmdSz = (int)(wcslen(conCmd) + cmdSz + 2); /* +1 for terminator */ - conCmdPtr = (PWSTR)WMALLOC(sizeof(wchar_t) * conCmdSz, NULL, DYNTYPE_SSHD); + conCmdSz = wcslen(conCmd) + cmdSz + 3; + /* +1 for terminator, +2 for quotes */ + conCmdPtr = (PWSTR)WMALLOC(sizeof(wchar_t) * conCmdSz, + NULL, DYNTYPE_SSHD); if (conCmdPtr == NULL) { ret = WS_MEMORY_E; } else { - memset(conCmdPtr, 0, conCmdSz * sizeof(wchar_t)); - _snwprintf(conCmdPtr, conCmdSz * sizeof(wchar_t), L"wolfsshd.exe -r \"%s\"", cmd); + _snwprintf_s(conCmdPtr, conCmdSz, conCmdSz, + L"wolfsshd.exe -r \"%s\"", cmd); } - ZeroMemory(&si, sizeof(STARTUPINFO)); - si.cb = sizeof(STARTUPINFO); + ZeroMemory(&si, sizeof(si)); + si.cb = sizeof(si); si.hStdInput = cnslIn; si.hStdOutput = cnslOut; @@ -967,7 +975,6 @@ static int SHELL_Subsystem(WOLFSSHD_CONNECTION* conn, WOLFSSH* ssh, CloseHandle(cnslOut); WFREE(conCmdPtr, NULL, DYNTYPE_SSHD); - CloseHandle(processInfo.hThread); } if (ret == WS_SUCCESS) { @@ -2374,21 +2381,21 @@ static int StartSSHD(int argc, char** argv) wolfSSH_Log(WS_LOG_ERROR, "[SSHD] Issue updating service status"); } } - - /* Create a stop event to watch on */ - serviceStop = CreateEvent(NULL, TRUE, FALSE, NULL); - if (serviceStop == NULL) { - serviceStatus.dwControlsAccepted = 0; - serviceStatus.dwCurrentState = SERVICE_STOPPED; - serviceStatus.dwWin32ExitCode = GetLastError(); - serviceStatus.dwCheckPoint = 1; - - if (SetServiceStatus(serviceStatusHandle, &serviceStatus) == FALSE) { - wolfSSH_Log(WS_LOG_ERROR, "[SSHD] Issue updating service status"); + if (ret == WS_SUCCESS) { + /* Create a stop event to watch on */ + serviceStop = CreateEvent(NULL, TRUE, FALSE, NULL); + if (serviceStop == NULL) { + serviceStatus.dwControlsAccepted = 0; + serviceStatus.dwCurrentState = SERVICE_STOPPED; + serviceStatus.dwWin32ExitCode = GetLastError(); + serviceStatus.dwCheckPoint = 1; + + if (SetServiceStatus(serviceStatusHandle, &serviceStatus) == FALSE) { + wolfSSH_Log(WS_LOG_ERROR, "[SSHD] Issue updating service status"); + } + return; } - return; } - if (cmdArgs != NULL) { LocalFree(cmdArgs); } @@ -2550,8 +2557,8 @@ static int SetupConsole(char* inCmd) HANDLE sOut; HANDLE sIn; HPCON pCon = 0; - COORD cord; - STARTUPINFOEX ext; + COORD cord = { 80,24 }; /* Default to 80x24.
