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-787 | The product writes data past the end, or before the beginning, of the intended buffer. |
| 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
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for unusual or malformed requests targeting the function AP_get_wired_clientlist_setClientsName, specifically those manipulating the clientsname_%d parameter with excessively long strings. Since the exploit is publicly available, network intrusion detection systems (NIDS) can be configured to look for such exploit patterns. 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 discontinuing the use of affected Linksys models (RE6500, RE6250, RE6300, RE6350, RE7000, RE9000) with vulnerable firmware versions, as no patches or vendor mitigations are currently available. Consider replacing these devices with alternative products. Additionally, restrict remote access to these devices and monitor network traffic for exploit attempts. [2]
Can you explain this vulnerability to me?
This vulnerability is a stack-based buffer overflow in certain Linksys router models (RE6500, RE6250, RE6300, RE6350, RE7000, and RE9000) in specific firmware versions. It occurs in the function AP_get_wired_clientlist_setClientsName within the mod_form.so file when the argument clientsname_0 is manipulated. The vulnerability can be exploited remotely, and a public exploit is available.
How can this vulnerability impact me? :
Exploiting this vulnerability can lead to a stack-based buffer overflow, which may allow an attacker to execute arbitrary code remotely with limited privileges. This can compromise the affected device's confidentiality, integrity, and availability, potentially leading to unauthorized access, data theft, or disruption of network services.
