CVE-2026-18753: CWE-321 Use of hard-coded cryptographic key in GeoVision Inc. GV-AS1620 (AS-Manager)
GeoVision Inc.'s GV-AS1620 (AS-Manager) firmware version 2.07 contains a hard-coded static RSA private key used by the Lighttpd web server for TLS termination. This vulnerability allows attackers to compromise HTTPS confidentiality and integrity by decrypting traffic and spoofing the server. The issue is classified as critical with a CVSS score of 9.1. No official patch or remediation guidance is currently available from the vendor.
AI Analysis
Technical Summary
CVE-2026-18753 is a critical vulnerability in GeoVision Inc.'s GV-AS1620 (AS-Manager) firmware version 2.07 where a static RSA private key is embedded in the product firmware. This key is used by the Lighttpd web server for TLS termination. Exposure of this hard-coded private key enables attackers to decrypt HTTPS communications and impersonate the server, compromising confidentiality and integrity of data in transit. The vulnerability is identified as CWE-321 (Use of hard-coded cryptographic key). No vendor advisory or patch information is currently provided.
Potential Impact
The exposure of a hard-coded RSA private key allows attackers to decrypt encrypted HTTPS traffic and perform server spoofing attacks. This compromises the confidentiality and integrity of communications between clients and the affected device. The vulnerability does not impact availability. The CVSS 3.1 base score is 9.1, indicating critical severity with network attack vector, low attack complexity, no privileges required, no user interaction, and high impact on confidentiality and integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider isolating the affected device from untrusted networks and monitoring for suspicious activity related to TLS communications. Replacement or reconfiguration of the device to avoid use of the vulnerable firmware version may be necessary.
