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-2025-14879 is a critical stack-based buffer overflow vulnerability in the Tenda WH450 router version 1.0.0.18. It exists in the HTTP Request Handler component, specifically in the /goform/onSSIDChange endpoint. The vulnerability arises from improper handling of the ssid_index argument, which when manipulated with crafted input causes a stack-based buffer overflow. This flaw can be exploited remotely without authentication by sending specially crafted HTTP requests, potentially allowing attackers to execute arbitrary code or cause denial of service on the device. [1, 3]
How can this vulnerability impact me? :
This vulnerability can severely impact you by allowing remote attackers to execute arbitrary code or cause denial of service on the affected Tenda WH450 router. This compromises the confidentiality, integrity, and availability of the device, potentially disrupting network operations or enabling further attacks through the compromised router. Since exploitation requires no authentication and is easy to perform, it poses a high risk to users of the affected device. [1, 3]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection can be performed by monitoring HTTP requests to the /goform/onSSIDChange endpoint on Tenda WH450 routers, specifically looking for unusually long or malformed ssid_index parameters that could trigger the stack-based buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such suspicious HTTP requests. Since the exploit is publicly available, signature-based detection using IDS/IPS tools referencing the known exploit pattern is possible. Specific commands are not provided in the resources. [1, 3]
What immediate steps should I take to mitigate this vulnerability?
There are no known countermeasures or mitigations currently available for this vulnerability. The recommended immediate step is to replace the affected Tenda WH450 router running firmware version 1.0.0.18 with an alternative device to eliminate the risk. Additionally, restricting remote HTTP access to the device and monitoring for exploit attempts may help reduce exposure until replacement. [1]
