description

HarnessRouter Docker images before 0.38.5 can allow organization members to configure provider endpoints that cause the service to request internal network resources. Exploitation requires a shared deployment in which untrusted organization members may save custom provider connections.

mitigation

Upgrade the HarnessRouter Docker image to version 0.38.5 or later. Until upgraded, prevent untrusted organizations from creating connections and restrict container egress to private, loopback, link-local, and cloud metadata addresses.

fixed in 0.38.5

outcome

Mechanism verified: the exploit fired on the vulnerable build and stayed silent on the patched one, but the server it ran against was ours, so no check ships for it.
