Jenkins Google Compute Engine Plugin has incorrect permission checks

CVE-2023-49652 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Jenkins Google Compute Engine Plugin 4.550.vb_327fca_3db_11 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.v5a_4dc98f6962 requires Overall/Administer permission for the affected HTTP endpoints.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
