Updated under an hour ago ()

It affects Red Hat Satellite 6.16 for RHEL 8 and 4 other products. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

A flaw was found in Foreman. A remote attacker could exploit a command injection vulnerability in Foreman's WebSocket proxy implementation. This vulnerability arises from the system's use of unsanitized hostname values from compute resource providers when constructing shell commands. By operating a malicious compute resource server, an attacker could achieve remote code execution on the Foreman server when a user accesses VM VNC console functionality. This could lead to the compromise of sensitive credentials and the entire managed infrastructure.
