CVE-2022-39309 | GoCD server secret encryption/decryption key leaked to agents during material serialization

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 leak the symmetric key used to encrypt/decrypt any secure variables/secrets in GoCD configuration to authenticated agents. A malicious/compromised agent may then expose that key from memory, and potentially allow an attacker the ability to decrypt secrets intended for other agents/environments if they also are able to obtain access to encrypted configuration values from the GoCD server. This issue is fixed in GoCD version 21.1.0. There are currently no known workarounds.

4.9 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/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: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.
