TITLE: phpMyAdmin HTTP Response Splitting Vulnerability
SECUNIA ADVISORY ID: SA17578
VERIFY ADVISORY: http://secunia.com/advisories/17578/
CRITICAL: Less critical
IMPACT: Exposure of system information, Cross Site Scripting
WHERE: >From remote
SOFTWARE: phpMyAdmin 2.x

http://secunia.com/product/1719/

DESCRIPTION: Toni Koivunen has reported a vulnerability in phpMyAdmin, which can be exploited by malicious people to conduct HTTP response splitting attacks. Some input passed to "libraries/header_http.inc.php" isn't properly sanitised before being returned to the user. This can be exploited to include arbitrary HTTP headers in a response sent to the user. Successful exploitation requires that "register_globals" is enabled. It is also possible to disclose the full path to certain scripts by accessing them directly. The vulnerability has been reported in versions prior to 2.6.4-pl4 and in version 2.7.0-beta1.

SOLUTION: Update to version 2.6.4-pl4.
