Overview

CVE-2014-4721 is a low-severity vulnerability affecting php php. It was published on July 6, 2014 and has a CVSS 2.0 base score of 2.6 (LOW).

This vulnerability has a CVSS 2.0 base score of 2.6, rated LOW. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The phpinfo implementation in ext/standard/info.c in PHP before 5.4.30 and 5.5.x before 5.5.14 does not ensure use of the string data type for the PHP_AUTH_PW, PHP_AUTH_TYPE, PHP_AUTH_USER, and PHP_SELF variables, which might allow context-dependent attackers to obtain sensitive information from process memory by using the integer data type with crafted values, related to a "type confusion" vulnerability, as demonstrated by reading a private SSL key in an Apache HTTP Server web-hosting environment with mod_ssl and a PHP 5.3.x mod_php.

Remediation

Check the references section for vendor advisories and patches from php. Update php to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
