Zero Day Initiative Advisory 09-046

Zero Day Initiative Advisory 09-046
Posted Jul 21, 2009
Authored by Tipping Point | Site zerodayinitiative.com

Zero Day Initiative Advisory 09-046 - This vulnerability allows remote attackers to execute arbitrary code on systems running vulnerable versions of Novell's Privileged User Manager. Authentication is not required to exploit this vulnerability. The specific flaw exists within the unifid.exe service which binds on port 29010 for a protocol providing RPC-like functionality encapsulated over SSL. This protocol allows a client to make a method call into a module. The 'spf' RPC call is implemented unsafely allowing remote attackers to load arbitrary modules over the network resulting in code execution under the context of the service.

-- About the Zero Day Initiative (ZDI):
Established by TippingPoint, The Zero Day Initiative (ZDI) represents
a best-of-breed model for rewarding security researchers for responsibly
disclosing discovered vulnerabilities.

Researchers interested in getting paid for their security research
through the ZDI can find more information and sign-up at:

The ZDI is unique in how the acquired vulnerability information is
used. TippingPoint does not re-sell the vulnerability details or any
exploit code. Instead, upon notifying the affected product vendor,
TippingPoint provides its customers with zero day protection through
its intrusion prevention technology. Explicit details regarding the
specifics of the vulnerability are not exposed to any parties until
an official vendor patch is publicly available. Furthermore, with the
altruistic aim of helping to secure a broader user base, TippingPoint
provides this vulnerability information confidentially to security
vendors (including competitors) who have a vulnerability protection or
mitigation product.
