43
FAUCET Score

CVE-2025-27590 is a critical vulnerability affecting oxidized-web (aka Oxidized Web) versions prior to 0.15.0, where an unauthenticated attacker can gain full control over the Linux user account running the application via the RANCID migration page. This vulnerability has a CVSS score of 9.8 (CRITICAL) due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability, allowing for complete system compromise. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, immediate patching is strongly recommended given the severe potential consequences.
