CVE-2023-40343 · GHSA-5r33-mgjf-6656
- Affected
- Maven io.jenkins.plugins:tuleap-oauth < 1.1.21
- Fixed in
- 1.1.21· Vendor fix available
- Issue
- Jenkins Tuleap Authentication Plugin 1.1.20 and earlier does not use a constant-time comparison when checking whether two authentication tokens are equal. This could potentially allow attackers to use statistical methods to obtain a valid authentication token. Tuleap Authentication Plugin 1.1.21 uses a constant-time comparison when validating authentication tokens.
Recommended action: Upgrade to 1.1.21 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
