Detailsinfo

A vulnerability classified as critical has been found in PHP up to 5.3.10 (Programming Language Software). This affects the function header. 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 integrity. The summary by CVE is:

The sapi_header_op function in main/SAPI.c in PHP before 5.3.11 and 5.4.x before 5.4.0RC2 does not check for %0D sequences (aka carriage return characters), which allows remote attackers to bypass an HTTP response-splitting protection mechanism via a crafted URL, related to improper interaction between the PHP header function and certain browsers, as demonstrated by Internet Explorer and Google Chrome.

The weakness was disclosed 08/30/2012 (Website). It is possible to read the advisory at bugs.php.net. This vulnerability is uniquely identified as CVE-2011-1398 since 03/10/2011.
