|
|
This module exploits a PHP code injection vulnerability in SPIP. The vulnerability exists
|
|
in the connect parameter, allowing an unauthenticated user to execute arbitrary commands
|
|
with web user privileges. Branches 2.0, 2.1, and 3 are affected. Vulnerable versions are
|
|
< 2.0.21, < 2.1.16, and < 3.0.3. This module is compatible with both Unix/Linux and Windows
|
|
platforms, and has been successfully tested on SPIP 2.0.11 and SPIP 2.0.20 on Apache running
|
|
on Ubuntu, Fedora, and Windows Server.
