CVE-2022-39310 | Malicious agent may be able to impersonate another agent in GoCD

GoCD is a continuous delivery server. GoCD helps you automate and streamline the build-test-release cycle for continuous delivery of your product. GoCD versions prior to 21.1.0 can allow one authenticated agent to impersonate another agent, and thus receive work packages for other agents due to broken access control and incorrect validation of agent tokens within the GoCD server. Since work packages can contain sensitive information such as credentials intended only for a given job running against a specific agent environment, this can cause accidental information disclosure. Exploitation requires knowledge of agent identifiers and ability to authenticate as an existing agent with the GoCD server. This issue is fixed in GoCD version 21.1.0. There are currently no known workarounds.

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:H)
They need powerful rights—admin, root, or similar—before this pays off.
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:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
