Vulnerable versions
-------------------------------------------------------------------------------
IAP-420 / 2.01e

Vulnerability overview
-------------------------------------------------------------------------------
1) Stored Cross-Site Scripting (CVE-2024-5410)
A Stored Cross-Site Scripting vulnerability was identified in the web interface
of the device. The SSID of the WiFi can be configured to contain arbitrary
JavaScript code. An attacker can exploit this vulnerability by luring a victim
to visit a malicious website. Furthermore, it is possible to hijack the session
of the attacked user.


2) Authenticated Command Injection (CVE-2024-5411)
The filename parameter of the config file upload is prone to a Command
Injection vulnerability. This vulnerability can only be exploited if a user is
authenticated to the web interface. This way, an attacker can invoke commands
and is able to get full control over the whole device.


Proof of Concept
-------------------------------------------------------------------------------
1) Stored Cross-Site Scripting (CVE-2024-5410)
Stored Cross-Site Scripting can be triggered by placing JavaScript code into
the SSID input field of the web interface as authenticated user. A single
request for injecting the script is shown below:
-------------------------------------------------------------------------------
POST /cgi-bin/wl_set.cgi HTTP/1.1
Host: 192.168.0.1
Accept-Language: de,en-US;q=0.7,en;q=0.3

-------------------------------------------------------------------------------

2) Authenticated Command Injection (CVE-2024-5411)
A command can be injected in the filename of the uploaded config. By sending a
request as shown below, the content of the current directory can be shown:
-------------------------------------------------------------------------------
POST /cgi-bin/admin_config.cgi?todo=upconf HTTP/1.1
Host: 10.69.10.2
User-Agent: Mozilla/5.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
