Detailsinfo

A vulnerability, which was classified as critical, was found in Novell Zenworks Desktops (version unknown). This affects an unknown function of the file zenrem32.exe of the component Remote Management. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Multiple stack-based and heap-based buffer overflows in Remote Management authentication (zenrem32.exe) on Novell ZENworks 6.5 Desktop and Server Management, ZENworks for Desktops 4.x, ZENworks for Servers 3.x, and Remote Management allows remote attackers to execute arbitrary code via (1) unspecified vectors, (2) type 1 authentication requests, and (3) type 2 authentication requests.

The bug was discovered 05/18/2005. The weakness was disclosed 05/19/2005 by Alex Wheeler (Website). It is possible to read the advisory at archives.neohapsis.com. This vulnerability is uniquely identified as CVE-2005-1543 since 05/14/2005. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

The exploit is shared for download at saintcorporation.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $25k-$100k.
