CVE-2025-56007 is a CRLF injection vulnerability in KeeneticOS prior to version 4.3, specifically targeting the "/auth" API endpoint. By exploiting this injection, an attacker can manipulate the HTTP response to add users with full permissions, effectively taking over the device. The attack requires user interaction (UI:R) but no privileges or authentication (PR:N). The vulnerability impacts availability (A:H) but not confidentiality or integrity. No patch or vendor advisory is currently provided, and no known exploits have been reported.

Successful exploitation allows an attacker to add users with full permissions on the affected device, resulting in complete device takeover. This can disrupt device availability and control but does not directly impact confidentiality or integrity according to the CVSS vector. The attack requires the victim to open a crafted page, indicating social engineering is necessary.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid opening untrusted links or pages that could trigger the exploit. Monitor KeeneticOS vendor communications for updates on patches or mitigations.
