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-2025-6616 is a critical stack-based buffer overflow vulnerability in the D-Link DIR-619L router firmware version 2.06B01. It occurs in the function formSetWAN_Wizard51, specifically involving the parameter curTime. An attacker can remotely supply an excessively long curTime value, which is not properly validated, causing a stack overflow. This overflow can crash the device and potentially allow the attacker to execute arbitrary code remotely. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by compromising the confidentiality, integrity, and availability of the affected device. Since the exploit can be triggered remotely without authentication, attackers can crash the router or execute arbitrary code, potentially taking control of the device. This can lead to network disruption, unauthorized access, and further exploitation within your network environment. [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 unusual or suspicious HTTP requests targeting the /goform/formSetWAN_Wizard51 endpoint with an abnormally long curTime parameter, which may indicate an attempted stack-based buffer overflow exploit. Network intrusion detection systems (NIDS) can be configured to alert on such patterns. Specific commands are not provided in the resources, but inspecting HTTP traffic for requests to /goform/formSetWAN_Wizard51 with excessively long curTime values is recommended. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected D-Link DIR-619L device running firmware version 2.06B01 with an alternative product, as no known mitigations or patches exist. Additionally, restricting remote access to the device and monitoring for exploit attempts can help reduce risk until replacement is possible. [2]
