Lifecycle Timeline
3DescriptionCVE.org
A flaw has been found in D-Link DWR-M920 up to 1.1.50. The impacted element is the function sub_412DA0 of the file /boafrm/formIMEISetup. This manipulation of the argument IMEI_value causes os command injection. The attack can be initiated remotely. The exploit has been published and may be used.
AnalysisAI
OS command injection in D-Link DWR-M920 firmware up to version 1.1.50 allows authenticated remote attackers to execute arbitrary shell commands on the device via the IMEI_value parameter of the /boafrm/formIMEISetup endpoint. The vulnerable function sub_412DA0 fails to sanitize attacker-controlled input before passing it to an OS-level command, granting low-privilege network access sufficient to achieve code execution with the confidence of a partial proof-of-concept. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires authenticated access to the DWR-M920 web management interface - the CVSS vector PR:L confirms that low-privilege credentials (such as a standard user or operator account, not necessarily full admin) are sufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.3 Medium score reflects the required low-privilege authentication (PR:L) as the primary risk-reducing factor - without it, this would score considerably higher. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained or guessed low-privilege credentials to the DWR-M920 web interface sends a crafted HTTP POST request to /boafrm/formIMEISetup with a malicious IMEI_value field containing shell metacharacters (e.g., a semicolon followed by a reverse shell payload). The unsanitized input is passed to function sub_412DA0, which executes the injected command in the router's OS context. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the D-Link advisory portal (https://www.dlink.com/) should be monitored for firmware updates targeting versions above 1.1.50. … Detailed patch versions, workarounds, and compensating controls in full report. |
