  • Exploit traffic is plaintext HTTP only (tls_state plaintext); TLS-inspected traffic is not required but encrypted sessions will evade detection.
  • Detect GET requests to /getcfg.php that include the POST body parameters _POST_SERVICES=DEVICE.ACCOUNT and AUTHORIZED_GROUP=1 — the URL-encoded percent signs (|25|) and equals sign (|3d|) are key fast-pattern anchors.
  • The attack targets the DEVICE.ACCOUNT service group, indicating the adversary is attempting to extract account/credential information from the router.
  • Snort/Suricata SID 2056733 (ET rule) can be used directly for perimeter and internal deployment with low performance impact and high confidence.
  • HTTP response status 200 from the target device confirms successful information disclosure; alert on 200 responses to /getcfg.php requests containing the exploit payload.
  • ·Affected firmware is DIR-845L version <=v1.01KRb03 only; ensure detection scope is limited to this device/firmware range to reduce false positives.
