CVE-2015-8770 roundcube: remote code execution
Last modified: 2017-03-14 11:29:48 EDT
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 "_skin" HTTP POST parameter in "/index.php" script when changing between different skins of the web application. A remote authenticated attacker can use path traversal sequences (e.g. "../../") to load a new skin from arbitrary location on the system, readable by the webserver.
