SNS Vulnerability

TYPO3 Cache Flooding Denial of Service and SQL Injection Vulnerabilities

Description

Two vulnerabilities have been reported in TYPO3, which can be exploited by malicious people to cause a DoS (Denial of Service) and to conduct SQL injection attacks.
1) An unspecified error when processing an invalid "cHash" parameter (cache hash) can be exploited to flood caching tables of the application.
Successful exploitation of this vulnerability requires that $TYPO3_CONF_VARS['FE']['disableNoCacheParameter'] is set to '1'.
This vulnerability is reported in versions 4.2.0 through 4.5.5.
2) Certain unspecified input passed to the application is not properly sanitised before being used in prepared queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation of this vulnerability requires that two or more parameters are bound to a prepared query and at least two of them are controlled by the attacker.
Note: The vendor reports that the TYPO3 Core is not affected by this vulnerability and that there is currently no known vector with regards to extensions from the TYPO3 Extension Repository (TER).
This vulnerability is reported in versions 4.5.0 through 4.5.5.
