CVE-2026-5984: Buffer Overflow in D-Link DIR-605L
CVE-2026-5984 is a high-severity buffer overflow vulnerability in the D-Link DIR-605L router firmware version 2. 13B01. The flaw exists in the formSetLog function of the POST Request Handler component, where improper handling of the curTime argument can lead to a buffer overflow. This vulnerability can be exploited remotely without user interaction and requires low privileges. The affected product is no longer supported by the vendor, and no official patch or remediation is available. Although an exploit is publicly available, there are no confirmed reports of exploitation in the wild.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the formSetLog function of the D-Link DIR-605L firmware 2.13B01. Specifically, manipulation of the curTime argument in the POST request handler leads to memory corruption. The vulnerability is remotely exploitable with low attack complexity and no user interaction required. The CVSS 4.0 base score is 8.7, indicating high severity due to high impact on confidentiality, integrity, and availability. The product affected is no longer maintained by D-Link, and no official fix or mitigation has been published.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code remotely on the affected device, potentially leading to full compromise of the router. This could impact the confidentiality, integrity, and availability of the device and the network it serves. Since the device is no longer supported, the risk remains unmitigated by vendor patches.
Mitigation Recommendations
No official patch or remediation is available from the vendor as the affected product is no longer supported. Users should consider discontinuing use of the vulnerable device or isolating it from critical networks to reduce risk. Monitoring for unusual network activity and replacing the device with a supported model are recommended steps.
