CVE-2026-5980: Buffer Overflow in D-Link DIR-605L
CVE-2026-5980 is a high-severity buffer overflow vulnerability in the D-Link DIR-605L router firmware version 2. 13B01. The flaw exists in the formSetMACFilter function within the POST Request Handler, where manipulation of the curTime argument can cause a buffer overflow. This vulnerability can be exploited remotely without user interaction and has a CVSS 4. 0 base score of 8. 7. The affected product is no longer supported by the vendor, and no official patch or remediation guidance is available. Although an exploit has been published, there are no confirmed reports of exploitation in the wild.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the formSetMACFilter function of the D-Link DIR-605L firmware version 2.13B01. The issue arises from improper handling of the curTime argument in a POST request, which can be manipulated remotely to overflow a buffer. The vulnerability has a high CVSS 4.0 score of 8.7, indicating significant impact potential. The affected device is no longer maintained by D-Link, and no official fix or patch has been released. Exploit code is publicly available, increasing the risk of potential attacks, although no active exploitation has been confirmed.
Potential Impact
Successful exploitation of this buffer overflow could allow remote attackers to cause a denial of service or potentially execute arbitrary code on the affected device. Given the high CVSS score and the nature of the vulnerability, the impact could be severe for affected routers. However, since the product is no longer supported and no patch is available, affected users remain exposed unless they upgrade hardware or implement alternative mitigations.
Mitigation Recommendations
No official patch or remediation is available from the vendor as the affected product is no longer supported. Users should consider replacing the affected D-Link DIR-605L devices with supported hardware to mitigate this vulnerability. Network-level protections such as firewall rules to restrict access to the device's management interface may reduce exposure. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance if available.
