CVE-2024-40085: n/a
A Buffer Overflow vulnerability in the local_app_set_router_wan function of Vilo 5 Mesh WiFi System <= 5.16.1.33 allows remote, unauthenticated attackers to execute arbitrary code via pppoe_username and pppoe_password fields being larger than 128 bytes in length.
AI Analysis
Technical Summary
CVE-2024-40085 is a buffer overflow vulnerability in the local_app_set_router_wan function of Vilo 5 Mesh WiFi System firmware versions <= 5.16.1.33. Remote attackers without authentication can exploit this by sending pppoe_username and pppoe_password fields exceeding 128 bytes, leading to arbitrary code execution. The vulnerability is categorized under CWE-120 (classic buffer overflow). No patch or vendor advisory is currently provided, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation allows remote, unauthenticated attackers to execute arbitrary code on affected devices, potentially leading to full compromise of the device, including control over confidentiality, integrity, and availability of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, restrict access to the device's WAN interface and monitor for unusual activity related to PPPoE configuration inputs.
