Multiple vulnerabilities in eGroupWare may lead to execution of arbitrary PHP code, the ability to upload malicious files and cross-site scripting attacks.
eGroupWare is a suite of web-based group applications including calendar, address book, messenger and email.
A vulnerability has been reported in FCKEditor due to the way that file uploads are handled in the file editor/filemanager/upload/php/upload.php when a filename has multiple file extensions (CVE-2008-2041). Another vulnerability exists in the _bad_protocol_once() function in the file phpgwapi/inc/class.kses.inc.php, which allows remote attackers to bypass HTML filtering (CVE-2008-1502).
The first vulnerability can be exploited to upload malicious files and execute arbitrary PHP code provided that a directory is writable by the webserver. The second vulnerability can be exploited by remote attackers via a specially crafted URL in order to conduct cross-site scripting attacks.
There is no known workaround at this time.
All eGroupWare users should upgrade to the latest version:
