CVE-2023-49652: Medium severity jenkins vulnerability
Incorrect permission checks in Jenkins Google Compute Engine Plugin 4.550.vb327fca3db11 and earlier allow attackers with global Item/Configure permission (while lacking Item/Configure permission on any particular job) to enumerate system-scoped credentials IDs of credentials stored in Jenkins and to connect to Google Cloud Platform using attacker-specified credentials IDs obtained through another method, to obtain information about existing projects. This fix has been backported to 4.3.17.1.
Other sources
Jenkins Google Compute Engine Plugin 4.550.vb327fca3db11 and earlier does not correctly perform permission checks in multiple HTTP endpoints. This allows attackers with global Item/Configure permission (while lacking Item/Configure permission on any particular job) to do the following:
- Enumerate system-scoped credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.
- Connect to Google Cloud Platform using attacker-specified credentials IDs obtained through another method, to obtain information about existing projects.
Google Compute Engine Plugin 4.551.v5a4dc98f6962 requires Overall/Administer permission for the affected HTTP endpoints.
