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-2025-7551 is a critical stack-based buffer overflow vulnerability in the Tenda FH1201 router firmware version 1.2.0.14(408). It exists in the function fromPptpUserAdd within the /goform/PPTPDClient file. The vulnerability arises from improper handling of the modino/username argument, where crafted input can overflow a buffer on the stack. This overflow can compromise the device's confidentiality, integrity, and availability. The vulnerability can be exploited remotely without authentication, and a proof-of-concept exploit is publicly available. [1, 2, 3]
How can this vulnerability impact me? :
This vulnerability can allow a remote attacker to execute arbitrary code or cause a denial of service on the affected Tenda FH1201 router. Because it can be exploited without authentication, an attacker can compromise the device's confidentiality, integrity, and availability, potentially disrupting network operations or gaining unauthorized control over the device. [1, 2, 3]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
There are no specific detection commands or network scanning techniques provided in the available resources. However, since the vulnerability is triggered via the /goform/PPTPDClient endpoint with crafted input to the modino/username parameters, monitoring HTTP requests to this endpoint for unusual or malformed parameters could help detect exploitation attempts. No official detection tools or commands are documented. [1, 2, 3]
What immediate steps should I take to mitigate this vulnerability?
No official patches or mitigations are currently available for this vulnerability. The recommended immediate step is to consider replacing the affected Tenda FH1201 device or firmware version 1.2.0.14(408) to avoid risk. Additionally, restricting remote access to the vulnerable endpoint and monitoring for exploit attempts may help reduce exposure. [1]
