|
|
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 in the /admicp/ directory to
|
|
make sure the user has admin rights. This is a broken authorization schema
|
|
because the header() function doesn't stop the execution flow.
|
|
This can be exploited by malicious users to execute admin functionality,
|
|
e.g. execution of arbitrary PHP code leveraging of plugins.php functionality.
