Summary

CVE-2025-67158 is a high-severity Improper Authentication (CWE-287) vulnerability in Revotech I6032W-Fhw Firmware. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 22.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement).

Deeper analysis

CVE-2025-67158, published on 2026-01-02, is an authentication bypass vulnerability (CWE-287) affecting the /cgi-bin/jvsweb.cgi endpoint in Revotech I6032W-FHW devices running versions v1.0.0014 through 20210517. Rated with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the flaw enables attackers to access sensitive information and escalate privileges by sending a crafted HTTP request.

Unauthenticated attackers with network access to the device can exploit this vulnerability remotely with low attack complexity and no user interaction required. Exploitation results in high-impact confidentiality loss, allowing unauthorized access to sensitive data and subsequent privilege escalation on the targeted system.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Auth bypass in public-facing CGI endpoint directly enables remote exploitation for initial access (T1190) and subsequent privilege escalation (T1068).

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

AC-14 explicitly identifies and restricts actions permitted without identification or authentication, preventing unauthorized access to sensitive CGI endpoints like /cgi-bin/jvsweb.cgi via crafted requests.

prevent

AC-3 enforces approved authorizations for logical access, ensuring authentication requirements block bypass vulnerabilities in device web endpoints.

prevent

AC-6 enforces least privilege to limit the scope of privilege escalation resulting from successful authentication bypass exploitation.
