CSRF vulnerability in Jenkins Active Directory Plugin

CVE-2020-2303 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Jenkins Active Directory Plugin 2.19 and earlier does not require POST requests for multiple HTTP endpoints implementing connection and authentication tests, resulting in cross-site request forgery (CSRF) vulnerabilities.

This vulnerability allows attackers to perform connection tests, connecting to attacker-specified or previously configured Active Directory servers using attacker-specified credentials.

Active Directory Plugin 2.20 requires POST requests 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:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
