A vulnerability was found in D-Link DIR-825M 1.1.8. Affected by this vulnerability is the function sub_456CF4 of the file /boafrm/formSysCmd of the component System Command Execution. Performing a manipulation of the argument sysCmd results in command injection. It is possible to initiate the attack remotely. The exploit has been made public and could be used.
AnalysisAI
Command injection in the D-Link DIR-825M router (firmware 1.1.8) allows network-adjacent authenticated attackers to execute arbitrary OS-level commands by manipulating the sysCmd argument submitted to the /boafrm/formSysCmd endpoint, processed by function sub_456CF4 without sanitization. A public proof-of-concept exploit exists and was published alongside the VulDB disclosure. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires low-privilege authentication to the DIR-825M web management interface (confirmed by PR:L in the CVSS 4.0 vector) - this is not an unauthenticated vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N) confirms network-reachable exploitation with no attack complexity and no user interaction, requiring only low-privilege authentication - a realistic bar for SOHO routers where default credentials remain common. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No specific patched firmware version was identified in the provided references - the D-Link advisory page was referenced generically without a CVE-specific bulletin. … Detailed patch versions, workarounds, and compensating controls in full report. |
