Summary
CVE-2026-32292 is a critical-severity Improper Restriction of Excessive Authentication Attempts (CWE-307) vulnerability in Gl-Inet Comet Gl-Rm1 Firmware. Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 43th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-32292 is a vulnerability in the GL-iNet Comet (GL-RM1) KVM web interface that fails to limit login requests, allowing brute-force attacks to guess credentials. Published on 2026-03-17, it is associated with CWE-307 (Improper Restriction of Excessive Authentication Attempts) and carries 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), reflecting high confidentiality impact from network-accessible exploitation with low complexity and no privileges required.
Remote attackers who can reach the device's web interface over the network can exploit this by performing unlimited login attempts with credential guesses. Success grants unauthorized access to the KVM interface, enabling high-impact confidentiality breaches, such as control over connected systems in environments where the device manages network access.
Advisories recommend mitigation via firmware update to version 1.7.2, available at https://dl.gl-inet.com/release/kvm/release/RM1/1.7.2. Additional guidance appears in an Eclypsium blog post titled "Your KVM is the Weak Link: How $30 Devices Can Own Your Entire Network," a CISA CSAF advisory at https://raw.githubusercontent.com/cisagov/CSAF/develop/csaf_files/IT/white/2025/va-26-076-01.json, and the official CVE record at https://www.cve.org/CVERecord?id=CVE-2026-32292.

Mitigating Controls (NIST 800-53 r5) AI
AC-7 directly enforces limits on consecutive failed logons, structurally blocking brute-force exploitation of the weakness.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Authentication enforcement directly includes lockout, throttling, and MFA policies that prevent brute-force attempts.
Behavioral monitoring of authentication activity can detect excessive failed attempts after they occur.
Generating auth logs enables later detection or forensics but does not itself restrict attempts.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
CAPTCHA, account lock-out after repeated failures, and alerts on excessive attempts directly stop automated brute-force guessing of credentials.
