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-2025-11328 is a critical stack-based buffer overflow vulnerability in the Tenda AC18 router firmware version 15.03.05.19(6318). It occurs in the /goform/SetDDNSCfg endpoint when processing the 'ddnsEn' parameter. Improper bounds checking allows an attacker to overflow the stack, potentially leading to arbitrary code execution or denial of service. The vulnerability can be exploited remotely without local access, and a public exploit is available. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing remote attackers to execute arbitrary code on the affected Tenda AC18 router or cause a denial of service, which compromises the device's confidentiality, integrity, and availability. Since the exploit is publicly available and easy to execute, it poses a significant security risk to the device and any network relying on it. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring network traffic for requests to the /goform/SetDDNSCfg endpoint with the ddnsEn parameter. Since the exploit involves sending specially crafted requests to this URL, inspecting HTTP requests targeting this endpoint for unusual or malformed ddnsEn values may indicate exploitation attempts. Specific commands are not provided in the resources, but using tools like curl or network intrusion detection systems (NIDS) to filter for requests containing /goform/SetDDNSCfg and ddnsEn parameter could help detect attempts. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
No known countermeasures or mitigations have been identified for this vulnerability. The suggested immediate step is to replace the affected Tenda AC18 router firmware version 15.03.05.19(6318) with an alternative product or firmware version that is not vulnerable. Additionally, restricting remote access to the device and monitoring for exploit attempts may help reduce risk until a fix is available. [2]
