Vulnerability Information

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated PHP packages that fix two security issues are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server.

A bug was discovered in the PEAR XML-RPC Server package included in PHP. If a PHP script is used which implements an XML-RPC Server using the PEAR XML-RPC package, then it is possible for a remote attacker to construct an XML-RPC request which can cause PHP to execute arbitrary PHP commands as the 'apache' user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-1921 to this issue.

When using the default SELinux 'targeted' policy on Red Hat Enterprise Linux 4, the impact of this issue is reduced since the scripts executed by PHP are constrained within the httpd_sys_script_t security context.

A race condition in temporary file handling was discovered in the shtool script installed by PHP. If a third-party PHP module which uses shtool was compiled as root, a local user may be able to modify arbitrary files. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-1751 to this issue.

Users of PHP should upgrade to these updated packages, which contain backported fixes for these issues.

Solution

Update the affected packages.

Public Exploits

Target Network Port(s): N/A
Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, Exploit-DB)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the RHEL 3 / 4 : php (RHSA-2005:564) vulnerability:

Metasploit: exploit/unix/webapp/php_xmlrpc_eval
[PHP XML-RPC Arbitrary Code Execution]
Exploit-DB: exploits/php/webapps/16882.rb
[EDB-16882: XML-RPC Library 1.3.0 - 'xmlrpc.php' Arbitrary Code Execution (Metasploit)]
Exploit-DB: exploits/php/webapps/43829.txt
[EDB-43829: PHPXMLRPC < 1.1 - Remote Code Execution]

Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.

WARNING: Beware of using unverified exploits from sources such as GitHub or Exploit-DB. These exploits and PoCs could contain malware. For more information, see how to use exploits safely.

How to Run

Here is how to run the RHEL 3 / 4 : php (RHSA-2005:564) 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 Red Hat Local Security Checks plugin family.
On the right side table select RHEL 3 / 4 : php (RHSA-2005:564) plugin ID 18648.
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 redhat-RHSA-2005-564.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a redhat-RHSA-2005-564.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - redhat-RHSA-2005-564.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 redhat-RHSA-2005-564.nasl -t <IP/HOST>

Go back to menu.
