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-2025-8131 is a critical stack-based buffer overflow vulnerability in the Tenda AC20 router version 16.03.08.05. It occurs in an unknown function within the file /goform/SetStaticRouteCfg, where improper validation of the argument list allows an attacker to supply oversized input, causing a stack overflow. This overflow can be exploited remotely to potentially compromise the device's confidentiality, integrity, and availability. [1, 2]
How can this vulnerability impact me? :
Exploitation of this vulnerability can allow a remote attacker to execute arbitrary code on the affected Tenda AC20 router. This can lead to full compromise of the device, affecting its confidentiality, integrity, and availability. As a result, attackers could control the router, disrupt network services, or intercept sensitive data passing through the device. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
No known mitigations or countermeasures have been identified for this vulnerability. It is suggested to replace the affected Tenda AC20 router running firmware version 16.03.08.05 with an alternative device to mitigate the risk. [1]
