Multiple cross site scripting (XSS) vulnerabilities have been discovered in content management system Joomla!.
The attacks require user login and allow users to impersonate administrator functions.
Three vulnerabilities affect core components of Joomla! version 1.70 and below and were found by the Burma-based YEHG hacking group.
The vulnerabilities were patched in Joomla! version 1.71.
One XSS vulnerability, which uses the searchword parameter, was previously reported to Joomla! but was not “completely” fixed, the hacking group said.
