CVE-2026-8260: Buffer Overflow in D-Link DCS-935L
A vulnerability was found in D-Link DCS-935L up to 1.10.01. The impacted element is the function SetDeviceSettings of the file /web/cgi-bin/hnap/hnap_service of the component HNAP Service. The manipulation of the argument AdminPassword results in buffer overflow. The attack can be executed remotely. The exploit has been made public and could be used.
AI Analysis
Technical Summary
The vulnerability CVE-2026-8260 affects D-Link DCS-935L devices running firmware up to version 1.10.01. It is caused by improper handling of the AdminPassword argument in the SetDeviceSettings function within the /web/cgi-bin/hnap/hnap_service component, leading to a buffer overflow condition. This flaw allows remote attackers to potentially execute arbitrary code or cause denial of service. The CVSS 4.0 base score is 8.7, indicating high severity, with attack vector network, low attack complexity, no privileges required, and no user interaction needed. The vulnerability has been publicly disclosed, but no vendor patch or official fix has been documented.
Potential Impact
Successful exploitation of this vulnerability could allow remote attackers to execute arbitrary code or disrupt the device's operation by triggering a buffer overflow via the AdminPassword parameter. This could compromise device integrity and availability. The vulnerability is exploitable remotely without authentication or user interaction, increasing its risk. However, no known exploits in the wild have been confirmed so far.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch has been documented, users should monitor D-Link communications for updates. Until a patch is available, consider limiting network exposure of the affected device, such as restricting access to the HNAP service from untrusted networks.
