Exploited by Malware: True

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that PHP, when used as a stand alone CGI processor for the Apache Web Server, did not properly parse and filter query strings. This could allow a remote attacker to execute arbitrary code running with the privilege of the web server. Configurations using mod_php5 and FastCGI were not vulnerable.

This update addresses the issue when the PHP CGI interpreter is configured using mod_cgi and mod_actions as described in /usr/share/doc/php5-cgi/README.Debian.gz; however, if an alternate configuration is used to enable PHP CGI processing, it should be reviewed to ensure that command line arguments cannot be passed to the PHP interpreter. Please see CVE-2012-2311 for more details and potential mitigation approaches.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected php5-cgi package.

How to Run

Here is how to run the Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : php5 vulnerability (USN-1437-1) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Ubuntu Local Security Checks plugin family.
On the right side table select Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : php5 vulnerability (USN-1437-1) plugin ID 59016.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl ubuntu_USN-1437-1.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a ubuntu_USN-1437-1.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - ubuntu_USN-1437-1.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state ubuntu_USN-1437-1.nasl -t <IP/HOST>

Go back to menu.
