No official patch or remediation guidance is currently available.
AI Analysis
Technical Summary
The GV-AS1620 (AS-Manager) product firmware version 2.07 includes an embedded static RSA private key utilized by the Lighttpd web server for TLS termination. The presence of this hard-coded cryptographic key (CWE-321) enables attackers to decrypt HTTPS traffic and impersonate the server, undermining the confidentiality and integrity of communications. This vulnerability is tracked as CVE-2026-18753 with a CVSS 3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). No vendor advisory or patch information is currently provided.
Potential Impact
Exposure of the static RSA private key allows attackers to decrypt encrypted HTTPS communications and perform server spoofing attacks. This compromises the confidentiality and integrity of data transmitted between clients and the GV-AS1620 device. Availability is not impacted. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider restricting network access to the affected device to trusted hosts only and monitor for suspicious activity related to TLS communications.
