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-787 | The product writes data past the end, or before the beginning, of the intended buffer. |
| 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-2025-5622 is a critical stack-based buffer overflow vulnerability in the D-Link DIR-816 router (firmware version 1.10CNB05). It occurs in the wirelessApcli_5g function when an attacker manipulates the parameters apcli_mode_5g, apcli_enc_5g, or apcli_default_key_5g with crafted input that exceeds expected lengths. This causes a stack overflow, allowing the attacker to crash the device or potentially execute arbitrary code remotely without authentication. [1, 2]
How can this vulnerability impact me? :
This vulnerability can severely impact the confidentiality, integrity, and availability of the affected device. An attacker can remotely exploit it without authentication to crash the router or execute arbitrary code, potentially taking full control of the device. This can lead to network disruption, unauthorized access, and compromise of data passing through the router. [2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection can be performed by monitoring for unusual or malformed HTTP requests targeting the /goform/wirelessApcli_5g endpoint with parameters apcli_mode_5g, apcli_enc_5g, or apcli_default_key_5g containing unusually long or crafted input that may trigger the buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such suspicious requests. Specific commands are not provided in the resources, but using tools like tcpdump or Wireshark to capture HTTP traffic and grep or similar tools to filter requests to /goform/wirelessApcli_5g with suspicious parameter lengths 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-816 router running firmware version 1.10CNB05, as no known countermeasures or patches exist. It is recommended to replace the affected product with an alternative device. Additionally, restricting network access to the device, especially blocking remote access to the vulnerable endpoint, can reduce exposure until replacement is possible. [2]
