PHP 5.3.x < 5.3.28 Multiple OpenSSL Vulnerabilities
high Nessus Plugin ID 71426
Language:
Synopsis
The remote web server uses a version of PHP that is potentially affected by multiple vulnerabilities.Description
According to its banner, the version of PHP installed on the remote host is 5.3.x prior to 5.3.28. It is, therefore, potentially affected by the following vulnerabilities :- A flaw exists in the PHP OpenSSL extension's hostname identity check when handling certificates that contain hostnames with NULL bytes. An attacker could potentially exploit this flaw to conduct man-in-the-middle attacks to spoof SSL servers. Note that to exploit this issue, an attacker would need to obtain a carefully-crafted certificate signed by an authority that the client trusts. (CVE-2013-4073, CVE-2013-4248)
- A memory corruption flaw exists in the way the openssl_x509_parse() function of the PHP OpenSSL extension parsed X.509 certificates. A remote attacker could use this flaw to provide a malicious, self-signed certificate or a certificate signed by a trusted authority to a PHP application using the aforementioned function. This could cause the application to crash or possibly allow the attacker to execute arbitrary code with the privileges of the user running the PHP interpreter. (CVE-2013-6420)
Note that this plugin does not attempt to exploit these vulnerabilities, but instead relies only on PHP's self-reported version number.
Solution
Upgrade to PHP version 5.3.28 or later.See Also
