Summary

CVE-2020-10181 is a critical-severity CSRF (CWE-352) vulnerability in Sumavision Enhanced Multimedia Router Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 4% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability is a cross-site request forgery flaw (CWE-352) in the goform/formEMR30 endpoint of Sumavision Enhanced Multimedia Router (EMR) 3.0.4.27. The component accepts unauthenticated requests that create new users with administrator privileges, as shown by a setString=new_user<*1*>administrator<*1*>123456 parameter.

An unauthenticated remote attacker can exploit the issue over the network without user interaction to add an administrator account and obtain full control of the device configuration and services. The CVSS 3.1 score of 9.8 reflects the absence of required credentials and the complete confidentiality, integrity, and availability impact.

The supplied references consist of public proof-of-concept material, including PacketStorm entries and a GitHub repository with demonstration code, but contain no vendor advisory or patch information.

addresses: CWE-352

Awareness training educates users on avoiding untrusted links and actions that can be exploited via CSRF.

addresses: CWE-352

Requiring user re-entry of credentials for sensitive actions prevents automated forgery of requests without active user participation.

addresses: CWE-352

Security testing regimens explicitly include checks for missing or ineffective anti-CSRF protections in web applications.

addresses: CWE-352

Detects anomalous request patterns consistent with cross-site request forgery.
