Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Name of the Vulnerable Software and Affected Versions Jenkins Google Login Plugin versions 1.7 and earlier

Description The issue is related to the use of a non-constant time comparison function when checking whether the provided and expected token are equal. This potentially allows attackers to use statistical methods to obtain a valid token.

Recommendations For Jenkins Google Login Plugin versions 1.7 and earlier, consider updating to a version that uses a constant time comparison function to mitigate the risk of token exposure. As a temporary workaround, restrict access to the plugin's token verification mechanism until a patch is available.
