Multiple stack-based buffer overflow vulnerabilities exist in the formPingCmd functionality of Planet WGR-500 v1.3411b190912. A specially crafted series of HTTP requests can lead to stack-based buffer overflow. An attacker can send a series of HTTP requests to trigger these vulnerabilities.This buffer overflow is related to the `submit-url` request parameter.

→Exploit targets HTTP POST requests to the exact URI /boafrm/formPingCmd (URI length is exactly 19 bytes) on Planet WGR-500 devices.
→The overflow is triggered via the `submit-url` request body parameter (also `ipaddr` and `counts` for related CVEs) when the parameter value exceeds 100 characters before an `&` or end-of-body.
→CVE-2025-54401 specifically relates to the `submit-url` request parameter in formPingCmd. ↗
→Traffic is expected in plaintext (no TLS); deploy detection at the network perimeter and internally.
→MITRE mapping: Initial Access (TA0001) via Exploit Public-Facing Application (T1190).

·The Snort/ET rule (sid:2065219) covers four related CVEs (CVE-2025-54399, CVE-2025-54400, CVE-2025-54401, CVE-2025-54402) with a single signature; a positive alert does not isolate which specific parameter/CVE was exploited without further body inspection.
·Affected product is Planet WGR-500 v1.3411b190912 only; the rule targets $HOME_NET (destination), so ensure networking equipment is included in the HOME_NET variable for accurate coverage.
