ZDI-11-118: Novell ZENworks Asset Management Path Traversal File Overwrite Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-11-118 April 11, 2011 -- CVE ID: CVE-2010-4229 -- CVSS: 10, (AV:N/AC:L/Au:N/C:C/I:C/A:C) -- Affected Vendors: Novell -- Affected Products: Novell Zenworks -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell ZENworks Asset Management. Authentication is not required to exploit this vulnerability. The specific flaw exists within a servlet provided within the Novell Zenworks distribution for uploading files. When processing the path name for the file, the servlet will allow a user to inject path traversal entities into the filename. Then, when the servlet downloads the provided file, the destination will store it to the user-provided location. This can lead to code execution under the context of the service. -- Vendor Response: Novell has issued an update to correct this vulnerability.
