Apache Portable Runtime up to 1.4.3 input validation

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 was found in Apache Portable Runtime up to 1.4.3. It has been classified as problematic. This affects some unknown functionality. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

tables/apr_hash.c in the Apache Portable Runtime (APR) library through 1.4.5 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.

The weakness was presented 02/10/2012 by Moritz Muehlenhoff (Website). The advisory is shared at svn.apache.org. This vulnerability is uniquely identified as CVE-2012-0840 since 01/19/2012. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 57955 (Mandriva Linux Security Advisory : apr (MDVSA-2012:019)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (73096), Exploit-DB (36669), Tenable (57955), SecurityFocus (BID 51917†) and Secunia (SA47862†). See VDB-4557, VDB-5200, VDB-60221 and VDB-59888 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
