Critical severity GitHub Reviewed Published May 24, 2022 to the GitHub Advisory Database • Updated Feb 15, 2023

Package

maven org.codehaus.mevenide:netbeans (Maven)

Affected versions

<= 3.1.4

Patched versions

None

Description

The "Apache NetBeans" autoupdate system does not validate SSL certificates and hostnames for https based downloads. This allows an attacker to intercept downloads of autoupdates and modify the download, potentially injecting malicious code. "Apache NetBeans" versions up to and including 11.2 are affected by this vulnerability. NetBeans releases before the Apache transition started may also be affected.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
