Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SC-23 Session Authenticity good match

prevent

SC-23 requires mechanisms such as anti-CSRF tokens to protect session authenticity, directly preventing forged requests from bypassing authorization in the Admin UI.

SI-10 Information Input Validation good match

prevent

SI-10 enforces validation of inputs including request origins or tokens, addressing CWE-20 improper input validation that enables this CSRF vulnerability.

SI-2 Flaw Remediation good match

prevent

SI-2 mandates timely flaw remediation including patching the specific CSRF vulnerability in EZCast Pro II version 1.17478.146 as per the advisory.

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.

attack.mitre.org →

T1204.001 Malicious Link Execution

An adversary may rely upon a user clicking a malicious link in order to gain execution.

attack.mitre.org →

Why these techniques?

CSRF in network-accessible Admin UI directly enables remote exploitation of public-facing web application (T1190); UI:R requirement indicates delivery via malicious link requiring user execution (T1204.001).

NVD Description

Cross-Site Request Forgery in Admin UI of EZCast Pro II version 1.17478.146 allows attackers to bypass authorization checks and gain full access to the admin UI

Deeper analysisAI

CVE-2026-24345 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Admin UI of EZCast Pro II version 1.17478.146. Published on 2026-01-27, this issue (mapped to CWE-20: Improper Input Validation and CWE-352: Cross-Site Request Forgery) allows attackers to bypass authorization checks, granting full access to the admin UI. It carries 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), reflecting high severity due to its potential for significant impact.

Attackers can exploit this vulnerability remotely over the network with low complexity and no required privileges, though it demands user interaction, such as an authenticated administrator visiting a malicious webpage or clicking a forged request. Successful exploitation enables full unauthorized access to the admin UI, resulting in high confidentiality, integrity, and availability impacts.

Mitigation guidance is available in the advisory from NTC Swiss at https://hub.ntc.swiss/ntcf-2025-32832, which security practitioners should consult for patching and workaround recommendations.
