What is CVE-2015-20129?

CrushFTP versions prior to 7.3.0 are susceptible to a cross-site request forgery vulnerability due to the lack of CSRF protection enabled by default. This vulnerability potentially allows attackers to trick an authenticated administrator into visiting a malicious webpage. Once this occurs, the attacker can submit unauthorized POST requests that may, for example, create new users with root access or modify critical server configurations without the administrator's consent.

Affected Version(s)

CrushFTP 0 < 7.3.0
