CVE-2025-66953
Published: 17 December 2025
Summary
CVE-2025-66953 is a high-severity CSRF (CWE-352) vulnerability in Nardamiteq Upc2 Firmware. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 16.4th 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 SC-23 (Session Authenticity) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2025-66953 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, affecting the narda miteq Uplink Power Control Unit (UPC2) version 1.17. The flaw exists in the Web-based management interface, specifically at the /system_setup.htm, /set_clock.htm, /receiver_setup.htm, /cal.htm?..., and /channel_setup.htm endpoints. It has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity due to network accessibility, low attack complexity, no required privileges, user interaction, and significant impacts on confidentiality, integrity, and availability.
A remote attacker can exploit this CSRF vulnerability by tricking an authenticated user into visiting a malicious webpage that submits forged requests to the affected endpoints. No privileges are needed from the attacker (PR:N), but the attack requires user interaction, such as clicking a link. Successful exploitation enables arbitrary code execution on the UPC2 device.

Mitigating Controls (NIST 800-53 r5) AI
SC-23 enforces session authenticity mechanisms such as anti-CSRF tokens or SameSite cookies, directly preventing forged requests to the vulnerable UPC2 web endpoints.
SI-10 requires validation of inputs to the affected endpoints (/system_setup.htm, /set_clock.htm, etc.), rejecting forged CSRF requests lacking valid tokens or origin checks.
SI-2 mandates identification, reporting, and correction of the specific CSRF flaw in UPC2 v1.17, including patching or implementing mitigations to prevent arbitrary code execution.
