Summary

CVE-2025-41646 is a critical-severity Incorrect Type Conversion or Cast (CWE-704) vulnerability in Kunbus Revpi Status. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — 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-2025-41646 is an authentication bypass vulnerability in a KUNBUS software package, stemming from incorrect type conversion as classified under CWE-704. The flaw carries a CVSS 3.1 base score of 9.8 and permits remote attackers to circumvent authentication controls, resulting in full compromise of the affected device.

An unauthenticated remote attacker can exploit the issue over the network with low attack complexity and no user interaction required. Successful exploitation grants complete control of the device, including the ability to read, modify, or disrupt its data and functionality.

Vendor advisories published by KUNBUS provide further details on the affected package and recommended actions; they are available at the referenced PSIRT JSON and product security pages. The associated EPSS score has remained at 0.3384 since disclosure with no material increase observed.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds incorrect type conversions or casts.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented development standards and tools can mandate safe typing, casting rules, and compiler checks that stop the weakness from being introduced.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles can require type-safe design and casting practices that structurally avoid incorrect conversions.
