Summary
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).
Description
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
