Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
A vulnerability has been discovered in PhpWiki, which can be exploited by malicious people to compromise a vulnerable system.

The "UpLoad" wiki page (index.php/UpLoad) fails to properly validate the extension of an uploaded file. The blacklist of disallowed file extensions does not include for example ".php3" and ".phtml". This can be exploited to upload files with such extensions and execute arbitrary PHP code on the server.

Successful exploitation requires being logged in and that the webserver is configured to execute PHP scripts with such extensions. In the default configuration of PhpWiki, no registration or validation is necessary to log in.

NOTE: The vulnerability is currently being actively exploited.

The vulnerability is confirmed in version 1.3.12p3. Other versions may also be affected.
