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

ForgeRock · Access Management (AM)

CVSS 9.8 EPSS 100% 1 public exploit ransomware Fix deadline passed 17 November 2021

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).

Why we say that

  • Linked by CISA to known ransomware campaigns
  • EPSS puts exploitation in the next 30 days at 100%
  • 1 public exploit published
  • CISA's federal remediation deadline (2021-11-17) has passed
  • CVSS 9.8 critical
  • Listed in the CISA Known Exploited Vulnerabilities catalogue

Every line above comes from a named public source. Where the evidence is thin, we say so rather than inventing confidence — see methodology.
