Headline
CVE-2022-39311: Compromised agents able to execute remote code on GoCD Server
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 are vulnerable to remote code execution on the server from a malicious or compromised agent. The Spring RemoteInvocation endpoint exposed agent communication and allowed deserialization of arbitrary java objects, as well as subsequent remote code execution. Exploitation requires agent-level authentication, thus an attacker would need to either compromise an existing agent, its network communication or register a new agent to practically exploit this vulnerability. This issue is fixed in GoCD version 21.1.0. There are currently no known workarounds.
Impact
GoCD versions prior to 21.1.0 are vulnerable to remote code execution on the server from a malicious or compromised agent. The Spring RemoteInvocation endpoint exposed for agent communication allowed deserialization of arbitrary java objects, and subsequent remote code execution. Exploitation requires agent-level authentication, thus an attacker would need to either compromise an existing agent, its network communication or register a new agent to practically exploit this vulnerability.
Patches
Fixed in GoCD 21.1.0.
