Low risk44th percentile - higher than 44% of all known CVEs
Summary
A buffer overflow vulnerability in the local_app_set_router_wan function of Vilo 5 Mesh WiFi System versions up to 5.16.1.33 allows remote, unauthenticated attackers to execute arbitrary code by sending pppoe_username and pppoe_password fields longer than 128 bytes.
Risk Assessment
An attacker can remotely take control of the mesh WiFi device, leading to network integrity compromise, traffic interception, or further attacks on other devices in the network.
Recommendation
Immediately update the firmware of the Vilo 5 Mesh WiFi System to a version newer than 5.16.1.33 that includes a fix for this vulnerability.
Other vulnerabilities in Vilo 5 Mesh WiFi System
See all- CVE-2024-40089Critical
A command injection vulnerability in Vilo 5 Mesh WiFi System version 5.16.1.33 and earlier allows remote, authenticated attackers to execute arbitrary code by injecting shell commands into the device name.
- CVE-2024-40087Critical
Vilo 5 Mesh WiFi System version 5.16.1.33 and earlier suffers from insecure permissions. Lack of authentication in the custom TCP service on port 5432 allows remote, unauthenticated attackers to gain administrative access to the router.
- CVE-2024-40086Critical
A buffer overflow vulnerability in the local_app_set_router_wifi_SSID_PWD function of Vilo 5 Mesh WiFi System version 5.16.1.33 and earlier allows remote, unauthenticated attackers to execute arbitrary code by sending a password longer than 64 bytes.
- CVE-2024-40083Critical
A buffer overflow vulnerability in the local_app_set_router_token function of Vilo 5 Mesh WiFi System version 5.16.1.33 and earlier. A remote, unauthenticated attacker can execute arbitrary code by reading the token and timezone JSON fields via sscanf into a fixed-length buffer.
- CVE-2024-40091Medium
Vilo 5 Mesh WiFi System version 5.16.1.33 and earlier lacks authentication in the Boa webserver, allowing remote, unauthenticated attackers to retrieve logs containing sensitive system information.
- CVE-2024-40090Medium
A vulnerability in Vilo 5 Mesh WiFi System version 5.16.1.33 and earlier allows remote information disclosure. An unauthenticated attacker can send a GET request to the index page, leaking memory addresses of uClibc and the stack.
Original NVD description (English source)
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.
