Threat & Defense Details

Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

AC-9 Previous Logon Notification

addresses: CWE-287

Detects unauthorized successful logons resulting from improper authentication implementations.

AT-1 Policy and Procedures

addresses: CWE-287

Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.

AT-2 Literacy Training and Awareness

addresses: CWE-287

Security awareness training instructs users on secure authentication practices and avoiding credential compromise.

AT-3 Role-based Training

addresses: CWE-287

Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.

AU-10 Non-repudiation

addresses: CWE-287

Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.

AU-14 Session Audit

addresses: CWE-287

Session content review can reveal authentication bypasses or failures in session establishment.

AU-6 Audit Record Review, Analysis, and Reporting

addresses: CWE-287

Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.

CA-2 Control Assessments

addresses: CWE-287

Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.

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.

attack.mitre.org →

Why these techniques?

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

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

An authentication bypass in the /cgi-bin/jvsweb.cgi endpoint of Revotech I6032W-FHW v1.0.0014 - 20210517 allows attackers to access sensitive information and escalate privileges via a crafted HTTP request.

Deeper analysisAI

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.
