Detailsinfo

A vulnerability was found in Symantec Messaging Gateway up to 9.5.3-3. It has been rated as problematic. This issue affects the function brightmail/export. The manipulation of the argument logFile with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality. The summary by CVE is:

Multiple directory traversal vulnerabilities in the management console in Symantec Messaging Gateway (SMG) 9.5.x allow remote authenticated users to read arbitrary files via a .. (dot dot) in the (1) logFile parameter in a logs action to brightmail/export or (2) localBackupFileSelection parameter in an APPLIANCE restoreSource action to brightmail/admin/restore/download.do.

The bug was discovered 04/17/2012. The weakness was released 11/30/2012 by Ben Williams with NGS Secure Research as 120 as confirmed posting (Full-Disclosure). It is possible to read the advisory at seclists.org. The public release was coordinated with Symantec. The identification of this vulnerability is CVE-2012-4347 since 08/16/2012. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known. The attack technique deployed by this issue is T1006 according to MITRE ATT&CK.

A public exploit has been developed by Ben Williams and been published immediately after the advisory. The exploit is available at exploit-db.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 132 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 62010 (Symantec Messaging Gateway 9.5.x Multiple Vulnerabilities (SYM12-013)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CGI abuses. The commercial vulnerability scanner Qualys is able to test this issue with plugin 12594 (Symantec Messaging Gateway Multiple Vulnerabilities (SYM12-013)).
