|
|
This module exploits an arbitrary command execution vulnerability in
|
|
Traq 2.0 to 2.3. It's in the admincp/common.php script.
|
|
|
|
This function is called in each script located into /admicp/ directory to
|
|
make sure the user has admin rights, but this is a broken authorization
|
|
schema due to the header() function doesn't stop the execution flow. This
|
|
can be exploited by malicious users to execute admin functionality resulting
|
|
for e.g. in execution of arbitrary PHP code leveraging of plugins.php
|
|
functionality.
