A vulnerability, which was classified as critical, was found in D-Link DI-7300G+ and DI-8200G 17.12.20A1/19.12.25A1. This affects an unknown part of the file msp_info.htm. The manipulation of the argument flag/cmd/iface leads to os command injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.

  • →Target HTTP GET requests to /msp_info.htm where the 'flag' parameter is present and the 'cmd' or 'iface' parameter contains OS command injection metacharacters (semicolon, newline, backtick, pipe, dollar sign) in URL-encoded or raw form.
  • →The flag parameter value must begin with 'cmd' or 'qos' to match the attack pattern; use this as an additional filter to reduce false positives.
  • →Attack is delivered over plaintext HTTP (not TLS); perimeter and internal network monitoring points are both relevant deployment locations.
  • →The exploit is remotely initiated and targets networking equipment (D-Link DI-7300G+ and DI-8200G); map to MITRE ATT&CK T1190 (Exploit Public-Facing Application) under tactic TA0001 (Initial Access).
  • ·The Snort/Suricata rule (sid:2065059) covers four CVEs simultaneously (CVE-2025-11335, CVE-2025-6899, CVE-2024-44414, CVE-2024-44402); a match does not exclusively confirm CVE-2025-6899 — triage is required to identify the specific vulnerability being exploited.
  • ·The affected file and injection point ('flag/cmd/iface' parameters in msp_info.htm) are shared across multiple D-Link CVEs; ensure firmware version context (17.12.20A1 for DI-7300G+, 19.12.25A1 for DI-8200G) is used to scope affected assets accurately.
