Novell ZENworks Asset Management 7.5 web console information disclosure vulnerability

Vulnerability Note VU#332412

Original Release Date: 2012-10-15 | Last Revised: 2012-11-01


The web console for Novell ZENworks Asset Management 7.5 contains an information disclosure vulnerability. This vulnerability allows a remote attacker to read any file with SYSTEM privileges and retrieve configuration parameters from ZENworks Asset Management.


The Novell ZENworks Asset Management web console is provided as a Java web application named rtrlet. Two HandleMaintenanceCalls, GetFile_Password and GetConfigInfo_Password have hard-coded credentials. GetFile_Password allows access to any file on the filesystem and GetConfigInfo_Password allows access to ZENworks Asset Management configuration parameters along with the back-end system's credentials.

A full technical analysis of the vulnerability is available on Rapid7's blog post entitled "New 0day Exploit: Novell ZENworks CVE-2012-4933 Vulnerability" and Metasploit exploit modules are publicly available.


A remote unauthenticated attacker may read any file accessible with SYSTEM privileges and retrieve configuration parameters from ZENworks Asset Management.
