Vulnerability from github – Published: 2026-06-05 18:31 – Updated: 2026-06-05 18:31

Details

NetMan 204 contains a hard-coded backdoor account with the username and password 'eurek' that grants administrative access. A remote, unauthenticated attacker can authenticate through the cgi-bin/login.cgi endpoint (for example /cgi-bin/login.cgi?username=eurek&password=eurek, which due to lax parameter validation can be shortened to /cgi-bin/login.cgi?username=eurek%20eurek) to obtain administrator privileges, allowing them to alter device configuration, enable the telnet/SSH services, and reset local user credentials.

Severity

9.8 (Critical)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
