|
|
|
|
info:
|
|
name: Netsweeper <=6.4.3 - Python Code Injection
|
|
author: dwisiswant0
|
|
severity: critical
|
|
description: |
|
|
Netsweeper through 6.4.3 allows unauthenticated remote code execution because webadmin/tools/unixlogin.php (with certain Referer headers) launches a command line with client-supplied parameters, and allows injection of shell metacharacters.
|
|
remediation: |
|
|
Upgrade to a patched version of Netsweeper (>=6.4.4) to mitigate this vulnerability.
