Security readout for executives and security teams
Plain-English summary
This is a critical memory corruption flaw reported in a D-Link DIR-605L/N300 router firmware build. A vulnerable router could be crashed or potentially taken over if exposed to untrusted network traffic. The public record does not name a fixed firmware version.
Executive priority
Prioritize any internet-exposed DIR-605L devices for immediate isolation or replacement. The technical impact is severe, and the absence of a confirmed fix in the provided sources raises operational risk for legacy deployments.
Technical view
CVE-2023-24348 describes a stack overflow through the curTime parameter at /goform/formSetACLFilter in D-Link DIR-605L v2.13B01. The CVSS 3.1 score is 9.8, reflecting network reachability, no required authentication, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely where D-Link DIR-605L/N300 routers running v2.13B01 remain in service, especially if management or web interfaces are reachable from untrusted networks. The CVE metadata lists affected vendor/product as n/a, so asset confirmation is required.
Exploitation context
The source bundle includes a public GitHub reference and CVE details, but CISA KEV status is false and no cited source here confirms active exploitation. Treat public technical disclosure as increasing risk, without claiming known exploitation.
Researcher notes
The core evidence is limited to the CVE description, CVSS vector, CWE-121/CWE-787, a D-Link bulletin landing page, and a public GitHub disclosure reference. Affected metadata is incomplete, so do not generalize beyond DIR-605L v2.13B01 without additional vendor confirmation.
Mitigation direction
- Inventory for DIR-605L/N300 routers and firmware v2.13B01.
- Check D-Link security guidance for fixed firmware, support, or end-of-life status.
- Remove affected router management interfaces from internet exposure.
- Restrict administration to trusted networks or VPN-only access.
- Replace unsupported affected devices if no vendor fix is available.
Validation and detection
- Confirm model and firmware from device administration records or asset inventory.
- Review external exposure scans for reachable router web management services.
- Check whether /goform/formSetACLFilter exists without sending overflow payloads.
- Verify compensating controls block untrusted access to management interfaces.
- Track D-Link bulletin updates before marking remediation complete.
