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?
CVE-2025-6615 is a critical stack-based buffer overflow vulnerability in the D-Link DIR-619L router firmware version 2.06B01. It occurs in the function formAutoDetecWAN_wizard4 when the argument curTime is manipulated with crafted input that is excessively long, causing a stack overflow. This overflow can allow a remote attacker to execute arbitrary code or crash the device. [1, 2]
How can this vulnerability impact me? :
This vulnerability can compromise the confidentiality, integrity, and availability of the affected router. An attacker can remotely exploit it to execute arbitrary code, potentially taking control of the device or causing it to crash, leading to denial of service or unauthorized access to network traffic. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for attempts to access the /goform/formAutoDetecWAN_wizard4 endpoint with unusually long or malformed curTime parameters, which may indicate exploitation attempts. Network intrusion detection systems (NIDS) can be configured to alert on HTTP requests targeting this specific URI with suspicious payloads. Specific commands depend on your environment, but for example, using curl to test the endpoint with a long curTime parameter can help verify if the device is vulnerable: curl -v --data "curTime=$(python3 -c 'print("A"*500)')" http://<router-ip>/goform/formAutoDetecWAN_wizard4. Additionally, reviewing router logs for crashes or unusual behavior after such requests can help detect exploitation attempts. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include discontinuing use of the affected D-Link DIR-619L router running firmware version 2.06B01, as no known countermeasures or patches are available. It is recommended to replace the affected product with a supported alternative. Additionally, restricting remote access to the router's management interface and implementing network-level protections such as firewall rules to block access to the /goform/formAutoDetecWAN_wizard4 endpoint can reduce exposure.
