EFM — Vulnerabilities & Security Advisories 13

EFM is a web-based email filtering and security solution designed to protect organizations from spam, malware, and other email-based threats. Historically, EFM has been vulnerable to multiple remote code execution (RCE) and cross-site scripting (XSS) flaws, often stemming from improper input validation and insufficient access controls. Privilege escalation vulnerabilities have also been prevalent, allowing authenticated users to gain elevated system access. The product's seven recorded CVEs highlight ongoing security challenges, with several critical RCE issues discovered in recent years. These vulnerabilities typically stem from the complex web interface and integration points, making EFM a persistent target for attackers seeking initial access to enterprise networks.
