CVE-2011-2889: templates/system/error.php in Joomla!

Security readout for executives and security teams

This is an information disclosure issue in Joomla before 1.5.23. Certain error handling behavior in templates/system/error.php could reveal the server installation path. That does not directly grant access, but it can help attackers map the environment for later attacks. Exposure is most likely on public Joomla installations running versions before 1.5.23, especially where verbose error output is reachable. The source bundle does not identify affected extensions, hosting stacks, or exact configurations. Treat this as a low-priority legacy exposure unless affected Joomla systems are internet-facing or already fragile. It should be remediated during normal maintenance, but path disclosure alone is not evidence of compromise. Mitigation focus: Upgrade Joomla installations older than 1.5.23 to the vendor-fixed release or successor guidance.; Disable public display of detailed errors where operationally feasible.; Review Joomla vendor advisory and release notes before changing legacy deployments..
