CVE-2025-2774 is a high-severity vulnerability in Webmin, the web-based system administration panel, affecting versions prior to 2.302. The flaw is caused by improper neutralization of CRLF sequences in CGI requests, allowing a remote authenticated attacker to submit specially crafted requests that alter request handling in a security-relevant way. Successful exploitation can lead to privilege escalation and arbitrary code execution, with execution occurring in the context of the root user on affected systems.
