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-2025-6292 is a critical stack-based buffer overflow vulnerability in the D-Link DIR-825 router firmware version 2.03. It occurs in the HTTP POST request handler function sub_4091AC due to improper use of the strcat function without proper bounds checking. This flaw allows an attacker to remotely send a specially crafted HTTP POST request that overflows a buffer on the stack, potentially leading to system compromise. [1, 2]
How can this vulnerability impact me? :
This vulnerability can be exploited remotely without authentication, making it highly accessible to attackers. Successful exploitation can compromise the confidentiality, integrity, and availability of the affected router, potentially allowing attackers to execute arbitrary code or disrupt network services. Since the affected device is no longer supported, no mitigations exist, increasing the risk of exploitation. [2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection of this vulnerability involves monitoring for specially crafted HTTP POST requests targeting the D-Link DIR-825 router firmware 2.03, specifically those that may trigger a stack-based buffer overflow in the HTTP POST request handler. Since the vulnerability is triggered by malformed HTTP POST requests, network traffic analysis tools like Wireshark or tcpdump can be used to capture and inspect POST requests to the device. Additionally, using curl or similar tools to send crafted POST requests to test for abnormal behavior may help detect exploitation attempts. However, no specific detection commands or signatures are provided in the available resources. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include discontinuing use of the affected D-Link DIR-825 router running firmware version 2.03, as the product is no longer supported and no known mitigations or patches exist. It is strongly recommended to replace the affected device with an alternative product that is actively maintained and secure. Network-level protections such as blocking incoming HTTP POST requests to the device or isolating the device from untrusted networks may reduce exposure but do not fully mitigate the vulnerability.
