DescriptionCVE.org

A security flaw has been discovered in Edimax BR-6675nD 1.12. Impacted is the function mp of the file /goform/mp of the component POST Request Handler. Performing a manipulation of the argument command results in command injection. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Command injection in Edimax BR-6675nD firmware 1.12 enables remote attackers with administrative credentials to execute arbitrary OS commands via the command argument in POST requests to the /goform/mp endpoint. Although a public exploit exists (referenced via a Notion-hosted POC), exploitation is constrained by the requirement for high-privilege authentication (CVSS PR:H), keeping the CVSS 4.0 score at 2.0 and EPSS at 0.23%. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Obtain or brute-force admin credentials
Delivery
Authenticate to /goform/mp web endpoint
Exploit
Inject OS command in POST command parameter
Execution
Firmware passes unsanitized input to shell interpreter
Impact
Execute arbitrary commands on router OS

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold valid high-privileged (administrative-level) credentials for the Edimax BR-6675nD web management interface - confirmed by CVSS PR:H. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Multiple signals converge on a low-to-moderate real-world risk rating. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained or brute-forced the administrative password for a network-accessible Edimax BR-6675nD management interface submits a crafted POST request to `/goform/mp` with a shell metacharacter-delimited OS command injected into the `command` parameter. The unpatched `mp` handler passes the unsanitized value directly to the system command interpreter, executing the attacker's payload with the web process's privilege level on the router. …
Remediation No vendor-released patch has been identified at time of analysis - the vendor was contacted prior to disclosure and did not respond, leaving no upstream fix available. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
