CVE-2023-4777Network attack vector

Credential capture via insufficient endpoint permission checks

Published Sep 8, 2023 · Updated Sep 25, 2024

Authorization flaws in Qualys Container Scanning Connector for Jenkins 1.6.2.6 and earlier allow remote authenticated users to capture credentials. Multiple HTTP endpoints accept global Item/Configure permission without verifying Item/Configure permission on a particular job, then expose credential IDs or initiate connections with a selected credential. A logged-in user with global Item/Configure permission can direct Jenkins to an attacker-controlled server and capture stored credentials.
