Risk Analysis

This critical vulnerability allows an unauthenticated attacker to escalate privileges due to incorrect privilege assignment. With a CVSS score of 9.8, this flaw is extremely severe and could lead to full system compromise. The lack of an EPSS score means the likelihood of exploitation is not yet quantified, but the high CVSS score indicates urgency.

No public exploit is currently known for this vulnerability. The attack vector is network-based with low attack complexity, making it remotely exploitable.

Recommended Action

To mitigate this, ensure proper privilege separation and access controls are enforced. Upgrade miniorange otp verification to a version beyond 5.4.9 as soon as a fix is available.
