CVE-2024-40084: n/a
A Buffer Overflow in the Boa webserver of Vilo 5 Mesh WiFi System <= 5.16.1.33 allows remote, unauthenticated attackers to execute arbitrary code via exceptionally long HTTP methods or paths.
AI Analysis
Technical Summary
This vulnerability is a buffer overflow (CWE-120) in the Boa webserver used by Vilo 5 Mesh WiFi System firmware versions <= 5.16.1.33. It can be triggered remotely without authentication by sending HTTP requests with excessively long methods or paths, leading to arbitrary code execution. The CVSS 3.1 base score is 9.6, reflecting critical severity with network attack vector, low attack complexity, no privileges required, no user interaction, and complete impact on confidentiality, integrity, and availability. There are no known exploits in the wild and no vendor-provided patch or mitigation at this time.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code on the affected device without authentication, potentially leading to full system compromise. This impacts confidentiality, integrity, and availability of the device and network it serves.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict network access to the affected device's management interfaces and monitor for unusual HTTP requests with abnormally long methods or paths.
