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-2025-7602 is a critical stack-based buffer overflow vulnerability in the D-Link DI-8100 router firmware version 16.07.26A1. It occurs due to improper handling of input in the /arp_sys.asp endpoint of the HTTP Request Handler component, which leads to a stack overflow. This flaw can be exploited remotely by sending specially crafted HTTP requests without requiring authentication, potentially causing a Denial of Service (DoS) condition. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing remote attackers to cause a Denial of Service (DoS) on affected D-Link DI-8100 routers, disrupting network availability. It compromises the confidentiality, integrity, and availability of the device. Exploitation is relatively easy and can be performed remotely, potentially leading to network outages or further attacks leveraging the compromised device. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by scanning for devices exposing the /arp_sys.asp endpoint, which is vulnerable to stack-based buffer overflow. One method is to use Google hacking techniques such as searching for 'inurl:arp_sys.asp' to identify potentially vulnerable devices. Additionally, network scanning tools like curl or wget can be used to send HTTP requests to the /arp_sys.asp endpoint and observe responses for anomalies or crashes. For example, a command like 'curl http://<target-ip>/arp_sys.asp' can be used to check if the endpoint is accessible. Monitoring for unusual HTTP requests targeting /arp_sys.asp or signs of Denial of Service (DoS) conditions on D-Link DI-8100 devices may also indicate exploitation attempts. [2, 1]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected D-Link DI-8100 device running firmware version 16.07.26A1 with an alternative product, as no known countermeasures or patches are reported. Limiting network exposure of the device by restricting access to the /arp_sys.asp endpoint through firewall rules or network segmentation can reduce risk. Monitoring network traffic for suspicious requests targeting this endpoint and disabling remote access to the device where possible are also recommended to mitigate exploitation risk. [2]
