Impact

Makunet Maku‑boot from 4.3.0 to 5.0.0 has a missing authorization flaw that allows any authenticated user to call the mail and SMS configuration listing endpoints. This exposes unmasked SMTP passwords, cloud provider access keys, and lets the attacker send mail to arbitrary recipients via the /sys/mail/config/send endpoint, compromising sensitive data and enabling further abuse.

Affected Systems

The vulnerability affects the Makunet Maku‑boot application, specifically all released versions from 4.3.0 through 5.0.0.

Risk and Exploitability

The CVSS score of 7.1 indicates a moderate severity. The EPSS score is not available, so the current estimated exploitation rate is unknown, and the vulnerability is not listed in the CISA KEV catalog. The flaw can be exploited by anyone with legitimate authentication credentials; it does not require remote code execution or elevated privileges beyond those already granted. An attacker could read sensitive configuration data and use the mail sending endpoint for phishing or spamming.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Makunet Maku‑boot to the latest version that removes the missing authorization checks.
  • If an upgrade is infeasible, immediately apply custom authorization controls to the /sys/mail/config/* and /sys/sms/config/* endpoints to restrict them to users with explicit authority.
  • Disable or restrict the /sys/mail/config/send endpoint for non‑privileged users to prevent misuse.
