Buffer Overflow vulnerability in Kerlink Kerlink Wirnet iStation 868 KerOS v.4.3.3_20200803132042 allows a remote attacker to obtain sensitive information via the update URLs component.

Kerlink gateways running KerOS prior to version 5.10 expose their web interface exclusively over HTTP, without HTTPS support. This lack of transport layer security allows a man-in-the-middle attacker to intercept and modify traffic between the client and the device.

Due to a firewall misconfiguration, Kerlink devices running KerOS prior to 5.12 incorrectly accept specially crafted UDP packets. This allows an attacker to bypass the firewall and access UDP-based services that would otherwise be protected.

The service wmp-agent of KerOS prior 5.12 does not properly validate so-called ‘magic URLs’ allowing an unauthenticated remote attacker to execute arbitrary OS commands as root when the service is reachable over network. Typically, the service is protected via local firewall.
