Synopsis

phpGroupWare and eGroupWare include an XML-RPC implementation which allows remote attackers to execute arbitrary PHP script commands.

2. Impact Information

Background

phpGroupWare and eGroupWare are web based collaboration software suites.

Description

The XML-RPC implementations of phpGroupWare and eGroupWare fail to sanitize input sent to the XML-RPC server using the "POST" method.

Impact

A remote attacker could exploit the XML-RPC vulnerability to execute arbitrary PHP script code by sending specially crafted XML data to the XML-RPC servers of phpGroupWare or eGroupWare.

3. Resolution Information

Workaround

There are no known workarounds at this time.

Resolution
