CVE-2026-18753 (GCVE-0-2026-18753)

Vulnerability from cvelistv5 – Published: 2026-08-04 07:08 – Updated: 2026-08-04 13:36

Title

Hardcoded Cryptographic Key on GV-AS1620 Controller Firmware (GV-ASManager)

Summary

The product firmware contains an embedded, static RSA private key utilized by the Lighttpd web server for TLS termination. Exposure of this private key allows malicious actors to breach the confidentiality and integrity of HTTPS communications, enabling traffic decryption and server spoofing.

Severity

9.1 (Critical)
