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` and `ipaddr` request parameters combined.

  • →Exploit targets HTTP POST requests to the exact URI /boafrm/formPingCmd (URI length is exactly 19 bytes) on Planet WGR-500 devices.
  • →Buffer overflow is triggered when any of the request body parameters `ipaddr`, `counts`, or `submit-url` contain a value of 100 or more characters (i.e., an oversized parameter value). Specifically for CVE-2025-54402, the `submit-url` and `ipaddr` parameters are combined.
  • →This buffer overflow is related to the `submit-url` and `ipaddr` request parameters combined. ↗
  • →Traffic is expected to be plaintext (non-TLS); deploy detection at the network perimeter and internally.
  • ·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; tuning or splitting may be needed to attribute alerts to a specific CVE.
  • ·The PCRE threshold of 100+ characters for the parameter value is the detection trigger; legitimate ping command parameters are far shorter, so false-positive risk is low, but the threshold could be adjusted if needed.
