CVE-2026-2925 identifies a stack-based buffer overflow vulnerability in the D-Link DWR-M960 router firmware version 1.01.07. The vulnerability resides in the Bridge VLAN Configuration Endpoint component, specifically in the function sub_42B5A0 located in the /boafrm/formBridgeVlan file. An attacker can exploit this flaw by manipulating the submit-url argument sent to this endpoint, causing a stack-based buffer overflow. This type of overflow can overwrite the stack memory, potentially allowing arbitrary code execution or crashing the device, leading to denial of service. The vulnerability is remotely exploitable without requiring authentication or user interaction, making it particularly dangerous. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (VC:H/VI:H/VA:H). Although no known exploits are currently active in the wild, the public availability of exploit code increases the likelihood of exploitation attempts. The lack of available patches at the time of publication necessitates immediate mitigation efforts. This vulnerability affects a specific firmware version, so organizations should verify their device versions and apply updates or mitigations accordingly.

The impact of CVE-2026-2925 is significant for organizations relying on the D-Link DWR-M960 router, especially those running firmware version 1.01.07. Exploitation can lead to complete compromise of the affected device, allowing attackers to execute arbitrary code with the privileges of the router’s software. This can result in unauthorized access to internal networks, interception or manipulation of network traffic, and disruption of network services through denial of service. The vulnerability threatens confidentiality, integrity, and availability simultaneously, making it a critical risk in environments where these routers serve as gateways or critical network infrastructure. Given the remote and unauthenticated nature of the exploit, attackers can target vulnerable devices over the internet or local networks without user interaction, increasing the attack surface. The public availability of exploit code further elevates the risk of widespread attacks, potentially impacting business continuity and data security. Organizations in sectors with high reliance on network infrastructure, such as telecommunications, government, and enterprises with remote sites, face elevated risks.

To mitigate CVE-2026-2925, organizations should first verify if they are using the D-Link DWR-M960 router with firmware version 1.01.07. If so, they should immediately check for any official firmware updates or patches released by D-Link addressing this vulnerability and apply them promptly. In the absence of an official patch, network administrators should restrict access to the router’s management interfaces by implementing network segmentation and firewall rules that limit access to trusted IP addresses only. Disabling remote management features, especially those accessible over the internet, can reduce exposure. Monitoring network traffic for unusual requests targeting the /boafrm/formBridgeVlan endpoint or suspicious submit-url parameters can help detect exploitation attempts. Employing intrusion detection/prevention systems (IDS/IPS) with signatures for this vulnerability or custom rules can provide additional defense. Regularly auditing device firmware versions and configurations, combined with maintaining an inventory of network devices, will facilitate rapid response to similar vulnerabilities. Finally, organizations should consider deploying network-level protections such as web application firewalls (WAFs) that can block malformed HTTP requests targeting this vulnerability.
