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-2025-7527 is a critical stack-based buffer overflow vulnerability in the Tenda FH1202 router firmware version 1.2.0.14(408). It occurs due to improper handling of the PPPOEPassword parameter in the fromAdvSetWan function accessed via the /goform/AdvSetWan endpoint. An attacker can send a specially crafted request to overflow the stack buffer, potentially leading to arbitrary code execution or denial of service. [1, 2]
How can this vulnerability impact me? :
This vulnerability can be exploited remotely without authentication, allowing attackers to execute arbitrary code or cause denial of service on the affected router. This compromises the router's confidentiality, integrity, and availability, potentially disrupting network operations and exposing sensitive data. [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 suspicious HTTP requests targeting the /goform/AdvSetWan endpoint with crafted PPPOEPassword parameters that may trigger a stack-based buffer overflow. Since the exploit involves sending specially crafted requests remotely without authentication, you can use network analysis tools like Wireshark or tcpdump to capture and inspect HTTP POST requests to /goform/AdvSetWan. Additionally, you may attempt to test the vulnerability by sending crafted requests to the endpoint using tools like curl or custom scripts to see if the device behaves abnormally or crashes. 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 replacing the affected Tenda FH1202 router or updating its firmware if a patch becomes available. Currently, no known mitigations or countermeasures exist for this vulnerability. It is recommended to isolate the vulnerable device from untrusted networks to reduce exposure and monitor for exploit attempts. Applying network-level protections such as firewall rules to block access to the /goform/AdvSetWan endpoint may help reduce risk until a fix is implemented. [2]
