CVE-2025-7091 — A vulnerability was found in Belkin F9K1122 1.00.33

High CVSS 9

A vulnerability was found in Belkin F9K1122 1.00.33. It has been classified as critical. Affected is the function formWlanMP of the file /goform/formWlanMP of the component webs. The manipulation of the argument ateFunc/ateGain/ateTxCount/ateChan/ateRate/ateMacID/e2pTxPower1/e2pTxPower2/e2pTxPower3/e2pTxPower4/e2pTxPower5/e2pTxPower6/e2pTxPower7/e2pTx2Power1/e2pTx2Power2/e2pTx2Power3/e2pTx2Power4/e2pTx2Power5/e2pTx2Power6/e2pTx2Power7/ateTxFreqOffset/ateMode/ateBW/ateAntenna/e2pTxFreqOffset/e2pTxPwDeltaB/e2pTxPwDeltaG/e2pTxPwDeltaMix/e2pTxPwDeltaN/readE2P leads to stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
