Improper Token Validation in Jenkins Generic Webhook Trigger Plugin

CVE-2022-43412

What is CVE-2022-43412?

The Generic Webhook Trigger Plugin for Jenkins versions up to 1.84.1 is vulnerable due to its use of a non-constant time comparison function for validating webhook tokens. This flaw could allow attackers to exploit the timing discrepancies inherent in the comparison process, potentially enabling them to deduce valid webhook tokens through statistical analysis. Such an exploit could facilitate unauthorized actions within Jenkins, making it critical for users to update their plugins and mitigate associated risks.
