PHP PHP_RSHUTDOWN_FUNCTION Security Bypass

medium Nessus Plugin ID 73289

Language:

Synopsis

The remote web server uses a version of PHP that is potentially affected by a security bypass vulnerability.

Description

According to its banner, the version of PHP 5.x installed on the remote host is 5.x prior to 5.3.11 or 5.4.x prior to 5.4.1 and thus, is potentially affected by a security bypass vulnerability.

An error exists related to the function 'PHP_RSHUTDOWN_FUNCTION' in the libxml extension and the 'stream_close' method that could allow a remote attacker to bypass 'open_basedir' protections and obtain sensitive information.

Note that this plugin has not attempted to exploit this issue, but has instead relied only on PHP's self-reported version number.

Solution

Upgrade to PHP version 5.3.11 / 5.4.1 or later.
