Security readout for executives and security teams
Plain-English summary
CVE-2023-24343 is a high-severity memory corruption flaw reported in D-Link DIR-605L v2.13B01 routers. An authenticated attacker who can reach the router management interface may be able to crash or take control of the device. Treat exposed or still-used units as priority network-edge risk.
Executive priority
Prioritize this for any site still using DIR-605L v2.13B01, especially if router administration is exposed beyond trusted networks. The issue affects a network edge device and has high impact, but public sources here do not confirm active exploitation.
Technical view
The CVE describes a stack overflow and out-of-bounds write involving the curTime parameter at /goform/formSchedule on D-Link N300 Wi-Fi Router DIR-605L v2.13B01. CVSS 3.1 is 8.8: network reachable, low complexity, low privileges required, no user interaction, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to organizations or homes still running D-Link DIR-605L v2.13B01. Risk rises if the management interface is reachable from untrusted networks. The CVE record’s affected product metadata is incomplete, so confirm device model and firmware directly.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. A public GitHub reference is listed, indicating public technical disclosure, but that alone is not evidence of in-the-wild exploitation. Authentication is required according to the CVSS vector.
Researcher notes
The record ties the issue to curTime at /goform/formSchedule and maps it to CWE-121 and CWE-787. Affected metadata in the bundle is sparse despite the description naming DIR-605L v2.13B01. Validate against firmware and vendor lifecycle data before broad claims.
Mitigation direction
- Check D-Link guidance for fixed firmware, lifecycle status, or replacement advice.
- Remove internet exposure from router administration interfaces.
- Restrict management access to trusted admin networks only.
- Replace or retire affected devices if no supported update exists.
- Use strong unique admin credentials and disable unused accounts.
Validation and detection
- Inventory D-Link DIR-605L routers and confirm firmware version v2.13B01.
- Verify management interfaces are not reachable from the internet.
- Review router logs for unexpected authenticated configuration activity.
- Confirm D-Link bulletin status before planning remediation.
- Avoid overflow reproduction on production devices.
