High-Tech Bridge Security Research Lab discovered a path traversal vulnerability in a popular webmail client Roundcube. Vulnerability can be exploited to gain access to sensitive information and under certain circumstances to execute arbitrary code and totally compromise the vulnerable server.
The vulnerability exists due to insufficient sanitization of
