Vulnerability from csaf_helmholzgmbhcokg - Published: 2025-06-24 10:00 - Updated: 2025-06-24 10:00
Summary
Vulnerabilities in myREX24/myREX24.virtual
Severity
Critical
Notes
Summary: The mb24api endpoint reachable when connected via VPN is missing authentication for sensitive functions. This can lead to information disclosure of user- and device names and to DoS.
Impact: Some limited sensitive data can be accessed and a DoS can be performed targeting a specific user/device.
Remediation: Update to latest version: 2.18.0
General Recommendation: Always use the latest available firmware version on all devices.
CVE-2025-3090

An unauthenticated remote attacker can obtain limited sensitive information and/or DoS the device due to missing authentication for critical function.
