This vulnerability is present in ZENworks Configuration Management (ZCM) which is part of the ZENworks Suite. A blast from the past? This is a similar vulnerability to ZDI-10-078 / OSVDB-63412, but it abuses a different parameter of the same servlet. However this time Novell: - Did not bother issuing a security advisory to their customers. - Did not credit me even though I did responsible disclosure. - Refused to provide a CVE number for months. - Did not update their ZENworks Suite Trial software with the fix (you can download it now from their site, install and test the PoC / Metasploit module). - Does not list the fix in the ZCM 11.3.2 update information (https://www.novell.com/support/kb/doc.php?id=7015776). >> Technical details: Vulnerability: Remote code execution via file upload and directory traversal CVE-2015-0779 Constraints: none; no authentication or any other information needed Affected versions: ZENworks Configuration Management 11.3.1 and below POST /zenworks/UploadServlet?uid=../../../opt/novell/zenworks/share/tomcat/webapps/&filename=payload.war <WAR file payload in the body> The WAR file will be automatically deployed to the server (on certain Windows and Linux installations the path can be "../webapps/"). A Metasploit module that exploits this vulnerability has been released. >> Fix: Upgrade to version ZENworks Configuration Management 11.3.2.
