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 TOTOLINK T10 router firmware version 4.1.8cu.5083_B20200521. It occurs in the sprintf function within the /cgi-bin/cstecgi.cgi file when processing the loginAuthUrl parameter. An attacker can send a specially crafted HTTP login request that causes excessive input to be copied into a fixed-size stack buffer without proper bounds checking, leading to memory corruption. This can be exploited remotely without authentication. [1, 2]
How can this vulnerability impact me? :
The vulnerability can lead to memory corruption resulting in denial of service or potentially remote code execution on the affected device. It impacts the confidentiality, integrity, and availability of the TOTOLINK T10 router. Since it can be exploited remotely without authentication, attackers can compromise the device, disrupt its operation, or take control of it. [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 HTTP requests to the TOTOLINK T10 router's web management interface, specifically looking for requests to /cgi-bin/cstecgi.cgi with the parameter loginAuthUrl containing unusually long or crafted input that could trigger a buffer overflow. Since the vulnerability is triggered by the 'action=login' parameter with manipulated 'loginAuthUrl', inspecting HTTP traffic for such patterns may help detect exploitation attempts. 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 TOTOLINK T10 router firmware version 4.1.8cu.5083_B20200521 with a secure version or a different product, as no known countermeasures or patches are currently available. Avoid exposing the device's web management interface to untrusted networks and restrict remote access to reduce the risk of exploitation. [2]
