TikiWiki, eGroupWare: Arbitrary command execution through XML-RPC TikiWiki and eGroupWare both include PHP XML-RPC code vulnerable to arbitrary command execution. tikiwiki egroupware 2005-08-24 2005-08-24 102374 102377 remote 1.8.5-r2 1.8.5-r2 1.0.0.009 1.0.0.009

TikiWiki is a full featured Free Software Wiki, CMS and Groupware written in PHP. eGroupWare is a web-based collaboration software suite. Both TikiWiki and eGroupWare include a PHP library to handle XML-RPC requests.

The XML-RPC library shipped in TikiWiki and eGroupWare improperly handles XML-RPC requests and responses with malformed nested tags.

A remote attacker could exploit this vulnerability to inject arbitrary PHP script code into eval() statements by sending a specially crafted XML document to TikiWiki or eGroupWare.

There is no known workaround at this time.
