ForgeRock Access Management (AM) Core Server Remote Code Execution Vulnerability

Exploited in attacks Used by ransomware Critical 9.8 Attack chance: >99.9%

What it is

ForgeRock AM server before 7.0 has a Java deserialization vulnerability in the jato.pageSession parameter on multiple pages. The exploitation does not require authentication, and remote code execution can be triggered by sending a single crafted /ccversion/* request to the server. The vulnerability exists due to the usage of Sun ONE Application Framework (JATO) found in versions of Java 8 or earlier

CISA: 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).

What to do

Apply updates per vendor instructions.
