AI-suggested
Given the critical nature of CVE-2025-10392 and the lack of an official patch, European organizations should implement immediate compensating controls. These include isolating affected devices from the internet and untrusted networks, restricting management interfaces to trusted IP addresses only, and deploying network-level protections such as Web Application Firewalls (WAFs) or Intrusion Prevention Systems (IPS) configured to detect and block malformed HTTP Host headers. Network segmentation should be enforced to limit the potential spread of an attacker who compromises a device. Monitoring network traffic for unusual patterns or spikes in HTTP requests with suspicious Host headers can provide early detection. Organizations should also engage with the vendor for updates and apply patches as soon as they become available. In parallel, conducting an inventory of all Mercury KM08-708H devices and upgrading firmware to unaffected versions or replacing vulnerable hardware should be prioritized. Finally, incident response plans should be updated to address potential exploitation scenarios related to this vulnerability.
Description
A vulnerability was detected in Mercury KM08-708H GiGA WiFi Wave2 1.1.14. This affects an unknown function of the component HTTP Header Handler. The manipulation of the argument Host results in stack-based buffer overflow. The attack can be executed remotely. The exploit is now public and may be used.
