TITLE

Novell ZENWorks Remote Management Agent DN Name Remote Code Execution Vulnerability

DESCRIPTION

When processing the Console DN field of incoming requests, the process can be made to overflow a stack buffer by 2 bytes. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell ZENWorks. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ZenRem32.exe process which listens by default on TCP and UDP ports 1761. When processing incoming connections with specific version fields the process fails to initialize a string buffer intended to hold the name of the client. After making allocations based on the size of the uninitialized string, ZenRem32 proceeds to convert the buffer between wide-char and multi-byte data types. As the pointer is directed at uninitialized memory, this can be abused to corrupt the heap. An attacker can leverage this to execute remote code under the context of the SYSTEM user. When handling the filename in a Read Request (0x01) packet type the process blindly copies user supplied data into a fixed-length buffer on the stack. Successful exploits will compromise the affected application. Failed exploit attempts will result in a denial-of-service condition. Novell ZENworks 7 Desktop Management 7 SP1 is vulnerable. ---------------------------------------------------------------------- Secure your corporate defenses and reduce complexity in handling vulnerability threats with the new Secunia Vulnerability Intelligence Manager (VIM).

This can be exploited to corrupt heap memory by sending a specially crafted packet to TCP or UDP port 1761. This can be exploited to cause a stack-based buffer overflow by sending a specially crafted packet to TCP or UDP port 1761. This can be exploited to cause a stack-based buffer overflow by sending a specially crafted packet to UDP port 69. SOLUTION: Apply Interim Release 4 Hot Patch 5.
