Description
Jenkins Build Failure Analyzer Plugin 2.4.1 and earlier does not perform a permission check in a connection test HTTP endpoint.
This allows attackers with Overall/Read permission to connect to an attacker-specified hostname and port using attacker-specified username and password.
Additionally, this HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
Build Failure Analyzer Plugin 2.4.2 requires POST requests and Overall/Administer permission for the affected HTTP endpoint.

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
Click to expand
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: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.
