Lifecycle Timeline
3DescriptionCVE.org
A vulnerability was found in Edimax BR-6675nD 1.12. The affected element is the function formWlanMP of the file /goform/formWlanMP of the component POST Request Handler. The manipulation of the argument ateFunc/ateGain/ateRate/ateChan/ateTxCount/e2pTx2Power1/e2pTx2Power2/e2pTx2Power3/e2pTx2Power4/e2pTx2Power5/e2pTx2Power6/e2pTx2Power7/e2pTxPower1/e2pTxPower2/e2pTxPower3/e2pTxPower4/e2pTxPower5/e2pTxPower6/e2pTxPower7/ateTxFreqOffset/ateMode/ateMacID/ateBW/ateAntenna/e2pTxFreqOffset/e2pTxPwDeltaB/e2pTxPwDeltaG/e2pTxPwDeltaMix/readE2P/e2pTxPwDeltaN results in command injection. The attack can be launched remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Command injection in Edimax BR-6675nD 1.12 router firmware allows authenticated remote attackers to execute arbitrary OS commands by manipulating over two dozen POST parameters in the formWlanMP wireless calibration handler. The vulnerable endpoint exposes ATE (Automated Test Equipment) and EEPROM power calibration parameters - none requiring special configuration to be present - that pass user input unsanitized to a system-level command interpreter. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold at minimum a low-privileged authenticated session on the Edimax BR-6675nD 1.12 web management interface, confirmed by CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 numeric score of 2.1 is misleadingly low given the attack vector profile: AV:N/AC:L/AT:N/PR:L/UI:N indicates network-reachable exploitation requiring no interaction, no special attack conditions, and only low-level credentials. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained low-privileged credentials to the Edimax BR-6675nD web interface - whether through default credentials, credential stuffing, or a prior compromise - sends a crafted HTTP POST request to /goform/formWlanMP with shell metacharacters injected into a parameter such as ateFunc or e2pTxPower1. The firmware passes the unsanitized value directly into a system command, executing attacker-controlled OS commands in the firmware process context. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the vendor did not respond to responsible disclosure, and no fix version is confirmed from any source. … Detailed patch versions, workarounds, and compensating controls in full report. |
