Joomla! JomSocial Vulnerability
Date: 13 February 2014
The purpose of this advisory is to bring attention to a vulnerability in the JomSocial component of the Joomla! Content Management System (CMS).
JomSocial versions 2.6.x., 2.8.x, 3.0.x and 3.1.x are vulnerable to remote code execution. JomSocial versions prior to 2.6.x have reached the end of life and consequently no security fixes are available. Successful exploitation of vulnerabilities in these products could lead to remote code execution attacks.
CCIRC recommends that organizations running versions 2.6.x., 2.8.x, 3.0.x and 3.1.x of the JomSocial component for Joomla! CMS should consider installing the security fix immediately, as any website running JomSocial is vulnerable to remote code execution attacks.
CCIRC strongly recommends that organizations using an earlier version than 2.6.x upgrade to the latest version and apply the security fix to ensure their website is not susceptible to these vulnerabilities.
If you think your website may have been affected, CCIRC recommends that you thoroughly examine your content management installation and the associated file structure for unwanted changes. Joomla! has published the following information to assist in recovery efforts. http://docs.joomla.org/Security_Checklist/You_have_been_hacked_or_defaced
CCIRC also recommends that organizations:
- Conduct an extensive review of system log files for signs of compromise.
- Consider running security software to assist in the detection and eradication of malicious software.
