Splunk 4.2/4.2.1/4.2.2/4.2.3/4.2.4 cross-site request forgery

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.

A vulnerability classified as problematic has been found in Splunk 4.2/4.2.1/4.2.2/4.2.3/4.2.4 (Log Management Software). Affected is an unknown code. The manipulation with an unknown input leads to a cross-site request forgery vulnerability. CWE is classifying the issue as CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

mappy.py in Splunk Web in Splunk 4.2.x before 4.2.5 does not properly restrict use of the mappy command to access Python classes, which allows remote authenticated administrators to execute arbitrary code by leveraging the sys module in a request to the search application, as demonstrated by a cross-site request forgery (CSRF) attack, aka SPL-45172.

The weakness was presented 01/03/2012 by Emmanuel Bouillon with NATO C3 Agency (Website). The advisory is shared for download at splunk.com. This vulnerability is traded as CVE-2011-4642 since 11/30/2011. The exploitability is told to be difficult. It is possible to launch the attack remotely. A authentication is needed for exploitation. Successful exploitation requires user interaction by the victim. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Gary O'Leary-Steele in Ruby and been published before and not just after the advisory. The exploit is shared for download at securityfocus.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 19 days. During that time the estimated underground price was around $0-$5k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 12546 (Splunk Prior to 4.2.5 Multiple Vulnerabilities (SP-CAAAGMM)).

Upgrading to version 4.2.1 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at Exploit-DB (18245). See 59871, 59870 and 59869 for similar entries.
