Novell ZENworks Handheld Management ZfHIPCND.exe Buffer Overflow
TSL ID: FSC20110125-06
1. Affected Software
Novell ZENworks Handheld Management 7.0
Reference: http://www.novell.com/products/zenworks/handhelds
2. Vulnerability Summary
A buffer overflow vulnerability exists in Novell ZENworks Handheld Management
that could be exploited by remote unauthenticated attackers to execute
arbitrary code with SYSTEM privileges on a vulnerable server.
3. Vulnerability Analysis
The vulnerability is due to a boundary error in the IP Conduit Service,
ZfHIPCND.exe. If a crafted packet is sent to the service on port 2400/TCP, it
allocates a fixed size heap buffer and copies the client device information
into it without validating the string size. This could be exploited by
attackers to overflow the buffer and possibly execute arbitrary code with the
privileges of the ZfHIPCND.exe service, by default SYSTEM.
