Jenkins Gogs Plugin uses non-constant time webhook token comparison

Low severity GitHub Reviewed Published Oct 25, 2023 to the GitHub Advisory Database • Updated Nov 11, 2023

Package

maven org.jenkins-ci.plugins:gogs-webhook (Maven)

Affected versions

<= 1.0.15

Patched versions

None

Description

Jenkins Gogs Plugin 1.0.15 and earlier does not use a constant-time comparison when checking whether the provided and expected webhook token are equal.

This could potentially allow attackers to use statistical methods to obtain a valid webhook token.

As of publication of this advisory, there is no fix.

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.
