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?
This vulnerability is a stack-based buffer overflow in the Tenda AC18 router firmware version 15.03.05.19(6318). It occurs due to improper handling of the 'Username' parameter in the HTTP request to the endpoint /goform/fast_setting_pppoe_set. An attacker can send a specially crafted request that causes the buffer allocated on the stack to overflow, potentially leading to device compromise. The exploit can be carried out remotely without authentication. [1, 2]
How can this vulnerability impact me? :
Exploitation of this vulnerability can compromise the confidentiality, integrity, and availability of the affected Tenda AC18 router. Since the attack can be performed remotely without authentication, an attacker could gain control over the device, disrupt network services, or use the device as a foothold for further attacks. [2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring HTTP requests to the endpoint /goform/fast_setting_pppoe_set for suspicious or unusually long Username parameter values that could trigger a stack-based buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such anomalous requests. Specific commands are not 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 AC18 device with an alternative product, as no known mitigations or countermeasures have been identified. Additionally, restricting remote access to the device and monitoring for exploit attempts may reduce risk until replacement is possible. [2]
