Description:
A vulnerability has been reported in TWiki, which potentially can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to an error in the handling of file uploads where a filename has multiple file extensions. This can be exploited to upload malicious script files inside the pub directory (e.g. a PHP script).
Successful exploitation may allow execution of script code depending on the HTTP server configuration (it requires e.g. an Apache server with the "mod_mime" module installed).
The vulnerability has been reported in the following releases:
* TWikiRelease04x00x03
