Summary

CVE-2022-40005 is a high-severity OS Command Injection (CWE-78) vulnerability in Intelbras Wifiber 120Ac Inmesh Firmware. Its CVSS base score is 8.8 (High).

Operationally, ranked in the top 12.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

CVE-2022-40005 is an OS command injection vulnerability (CWE-78) affecting Intelbras WiFiber 120AC inMesh devices running firmware versions prior to 1-1-220826. The flaw resides in the web management interface and can be triggered through the /boaform/formPing6 and /boaform/formTracert endpoints used for IPv6 ping and traceroute operations.

Authenticated users with network access can supply crafted input to these endpoints, resulting in arbitrary command execution on the underlying system. With a CVSS score of 8.8, successful exploitation grants an attacker full control over confidentiality, integrity, and availability without requiring user interaction.

Public disclosures at the referenced URLs detail the issue but do not describe vendor-supplied patches or official mitigation steps. The associated EPSS score rose from lower values to a peak of 0.0570 in December 2025 before receding to the current 0.0335, indicating a period of increased exploitation interest after initial publication.
