Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
www-apps/tikiwiki < 1.8.5-r2 >= 1.8.5-r2 All supported architectures

TikiWiki and eGroupWare both include PHP XML-RPC code vulnerable to arbitrary command execution.

2.  Impact Information


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.

3.  Resolution Information


There is no known workaround at this time.


All TikiWiki users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/tikiwiki-1.8.5-r2"

All eGroupWare users should upgrade to the latest version:

Code Listing 3.2: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/egroupware-"
