Detailsinfo

A vulnerability was found in F5 BIG-IP up to 11.x (Firewall Software). It has been rated as problematic. Affected by this issue is some unknown functionality of the component Configuration Utility. 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:

Directory traversal vulnerability in the configuration utility in F5 BIG-IP before 12.0.0 and Enterprise Manager 3.0.0 through 3.1.1 allows remote authenticated users to access arbitrary files in the web root via unspecified vectors.

The weakness was published 09/09/2015 as SOL17253 as confirmed knowledge base article (Website). The advisory is shared for download at support.f5.com. This vulnerability is handled as CVE-2015-4040 since 05/19/2015. The attack may be launched remotely. A simple authentication is required for exploitation. Technical details are unknown but a public exploit is available. The MITRE ATT&CK project declares the attack technique as T1006.

A public exploit has been developed by Karn Ganeshen and been published 2 months after the advisory. 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 85891 (F5 Networks BIG-IP : BIG-IP Configuration utility vulnerability (SOL17253)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family F5 Networks Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 370203 (F5 BIG-IP ASM Configuration Utility Directory Traversal Vulnerability (K17253)).

Upgrading to version 12.0.0 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The best possible mitigation is suggested to be patching the affected component. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (38448), Tenable (85891), SecurityTracker (ID 1033532†) and Vulnerability Center (SBV-52814†). Once again VulDB remains the best source for vulnerability data.
