CVE-2025-30237: Authentication Bypass via Broken Access Control in Web Server in Multiple TP-Link Aginet Devices

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.33% (FIRST EPSS).
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The affected TP-Link Aginet devices contain a flaw in the web management interface where authentication checks are not consistently enforced on certain endpoints. An attacker can send specially crafted requests to bypass authentication and directly invoke privileged functionality without valid credentials. This issue arises from improper enforcement of access control mechanisms on sensitive operations. Successful exploitation may allow an unauthenticated attacker to execute privileged operations and gain full control of the device.
