Pedro Ribeiro has discovered multiple vulnerabilities in eGroupWare, which can be exploited by malicious users to manipulate certain data.
Input passed via multiple parameters to multiple scripts is not properly sanitised before being used in a call to the "unserialize()" function. This can be exploited to create or overwrite arbitrary files.
List of affected scripts and parameters:
Note: This can further be exploited to execute arbitrary PHP code via a specially crafted serialized object.
Successful exploitation requires knowledge of the full path of the file that is being written and the application to be running on a UNIX/Linux OS.
The vulnerabilities are confirmed in version 1.8.005.20131007. Prior versions may also be affected.
Solution: Update to version 1.8.006.20140217.
