Detailsinfo

A vulnerability was found in PHP up to 4.4.6 (Programming Language Software). It has been declared as problematic. Affected by this vulnerability is the function mcrypt_create_iv of the component Encryption Key. The manipulation of the argument seed with an unknown input leads to a missing encryption vulnerability. The CWE definition for the vulnerability is CWE-311. The product does not encrypt sensitive or critical information before storage or transmission. As an impact it is known to affect confidentiality. The summary by CVE is:

The mcrypt_create_iv function in ext/mcrypt/mcrypt.c in PHP before 4.4.7, 5.2.1, and possibly 5.0.x and other PHP 5 versions, calls php_rand_r with an uninitialized seed variable and therefore always generates the same initialization vector (IV), which might allow context-dependent attackers to decrypt certain data more easily because of the guessable encryption keys.

The bug was discovered 05/10/2007. The weakness was presented 05/10/2007 (Website). The advisory is shared at fortheloot.com. This vulnerability is known as CVE-2007-2727 since 05/16/2007. The exploitation appears to be difficult. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1600 for this issue.
