TYPO3 6.2/6.2.0/6.2.1/6.2.2 Extbase Framework information disclosure

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 classified as problematic has been found in TYPO3 6.2/6.2.0/6.2.1/6.2.2 (Content Management System). This affects an unknown code block of the component Extbase Framework. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. The summary by CVE is:

The query caching functionality in the Extbase Framework component in TYPO3 6.2.0 before 6.2.3 does not properly validate group permissions, which allows remote authenticated users to read arbitrary queries via unspecified vectors.

The weakness was disclosed 05/22/2014 by Jan Kiesewetter as TYPO3-CORE-SA-2014-001 as confirmed advisory (Website). It is possible to read the advisory at typo3.org. This vulnerability is uniquely identified as CVE-2014-3946 since 06/03/2014. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1592 according to MITRE ATT&CK. The advisory points out:

Failing to respect user groups of logged in users when caching queries, Extbase is susceptible to information disclosure. The query caching (introduced in Extbase 6.2) used to cache queries that query results for a specific user group were presented to a different group.

Upgrading to version 6.2.3 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (93463), SecurityFocus (BID 67624†), Secunia (SA58901†) and Vulnerability Center (SBV-45082†). The entries VDB-13346, VDB-13345, VDB-13344 and VDB-13343 are pretty similar. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
