Exploitability
| CWE ID | Description |
|---|---|
| CWE-119 | The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |
| CWE-121 | A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). |

AI Powered Q&A
Can you explain this vulnerability to me?
[{'type': 'paragraph', 'content': 'CVE-2026-2885 is a critical stack-based buffer overflow vulnerability found in the D-Link DWR-M960 router, version 1.01.07. The flaw exists in the function sub_469104 within the file /boafrm/formIpv6Setup. It arises from improper handling of the "submit-url" argument, where an attacker can supply an excessively long input that is copied without bounds checking into a fixed-size buffer, causing a stack-based buffer overflow.'}, {'type': 'paragraph', 'content': 'This overflow can lead to memory corruption, potentially allowing an attacker to execute arbitrary code with the privileges of the web server (typically root) or cause denial of service by crashing the device. The vulnerability can be exploited remotely without local access or physical interaction.'}] [1, 2, 3]
How can this vulnerability impact me? :
[{'type': 'paragraph', 'content': 'Exploitation of this vulnerability can compromise the confidentiality, integrity, and availability of the affected device.'}, {'type': 'list_item', 'content': "An attacker can cause denial of service by crashing the router's web server or causing the device to reboot unexpectedly."}, {'type': 'list_item', 'content': "More critically, an attacker could achieve arbitrary code execution, allowing them to hijack the device's execution flow with root privileges."}, {'type': 'paragraph', 'content': 'Because the attack can be performed remotely without authentication, it poses a high risk to network security and device stability.'}] [1, 2, 3]

How can this vulnerability be detected on my network or system? Can you suggest some commands?
[{'type': 'paragraph', 'content': 'This vulnerability can be detected by monitoring for unusual POST requests to the endpoint /boafrm/formIpv6Setup on the D-Link DWR-M960 router, specifically those containing the parameters save_apply and an excessively long submit-url value.'}, {'type': 'paragraph', 'content': 'A proof-of-concept involves sending a POST request with the save_apply parameter set and a crafted, overly long submit-url parameter that triggers the buffer overflow.'}, {'type': 'paragraph', 'content': "To detect exploitation attempts or test for the vulnerability, you can use network monitoring tools or curl commands to send crafted POST requests and observe the device's response or crashes."}, {'type': 'list_item', 'content': 'Example curl command to test the vulnerability: curl -X POST http://<router-ip>/boafrm/formIpv6Setup -d "save_apply=1&submit-url=$(python3 -c \'print("A"*1000)\')"'}, {'type': 'paragraph', 'content': "Monitoring logs for crashes or unexpected reboots of the router's web server (boa) can also indicate exploitation attempts."}] [2]
What immediate steps should I take to mitigate this vulnerability?
[{'type': 'paragraph', 'content': 'No known mitigations or countermeasures have been identified for this vulnerability.'}, {'type': 'paragraph', 'content': 'The recommended immediate step is to replace the affected D-Link DWR-M960 router running firmware version 1.01.07 with an alternative device that is not vulnerable.'}, {'type': 'paragraph', 'content': "Until replacement, restrict remote access to the router's management interface to trusted networks only, and monitor for suspicious activity targeting the /boafrm/formIpv6Setup endpoint."}] [1]
