What it is

ForgeRock Access Management (AM) Core Server allows an attacker who sends a specially crafted HTTP request to one of three endpoints (/ccversion/Version, /ccversion/Masthead, or /ccversion/ButtonFrame) to execute code in the context of the current user (unless ForgeRock AM is running as root user, which the vendor does not recommend).

2. Apply the fix. Apply updates per vendor instructions.
3. If you can't patch today, take the affected service off the internet or restrict who can reach it, and check its logs for signs of compromise since 22 Jul 2021.
4. Get told next time. Email alerts when CISA adds a CVE for ForgeRock.
