Samba up to 3.5.0 Default Configuration path traversal

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as problematic, has been found in Samba (File Transfer Software). Affected by this issue is an unknown code of the component Default Configuration. The manipulation 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. CVE summarizes:

The default configuration of smbd in Samba before 3.3.11, 3.4.x before 3.4.6, and 3.5.x before 3.5.0rc3, when a writable share exists, allows remote authenticated users to leverage a directory traversal vulnerability, and access arbitrary files, by using the symlink command in smbclient to create a symlink containing .. (dot dot) sequences, related to the combination of the unix extensions and wide links options.

The weakness was disclosed 03/10/2010 by Ronald Volgers as Bug 7104 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.samba.org. This vulnerability is handled as CVE-2010-0926. The attack may be launched remotely. A simple authentication is needed for exploitation. Technical details are unknown but a public exploit is available. The MITRE ATT&CK project declares the attack technique as T1006.

The exploit is available at exploit-db.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 68484 (Oracle Linux 5 : samba (ELSA-2012-0313)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165212 (SUSE Security Update for Multiple Packages (SUSE-SR:2010:014)).

Upgrading to version 3.5.0 eliminates this vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 8247.

The vulnerability is also documented in the databases at X-Force (56111), Exploit-DB (33599), Tenable (68484), SecurityFocus (BID 37992†) and Secunia (SA39317†). The entries VDB-52020, VDB-51880, VDB-51780 and VDB-50634 are pretty similar. VulDB is the best source for vulnerability data and more expert information about this specific topic.
