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-120 | The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-6137 is a critical buffer overflow vulnerability in the TOTOLINK T10 router firmware version 4.1.8cu.5207. It occurs in the function setWiFiScheduleCfg within the file /cgi-bin/cstecgi.cgi, where the 'desc' argument from an HTTP POST request is improperly handled. This improper handling causes a buffer overflow, allowing an attacker to potentially execute arbitrary code or cause a denial of service remotely without authentication. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by compromising the confidentiality, integrity, and availability of the affected TOTOLINK T10 device. An attacker can remotely exploit the buffer overflow to execute arbitrary code or cause the device to crash (denial of service), potentially taking control of the device or disrupting its normal operation. [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 POST requests to the endpoint /cgi-bin/cstecgi.cgi, specifically looking for requests to the setWiFiScheduleCfg function with unusually large or malformed 'desc' parameters that could trigger a buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such suspicious POST requests. Additionally, manual inspection or use of tools like curl or wget to send crafted POST requests to the vulnerable endpoint can help verify if the system is affected. Example command to test the endpoint: curl -X POST http://<target-ip>/cgi-bin/cstecgi.cgi -d "action=setWiFiScheduleCfg&desc=$(python3 -c 'print("A"*1000)')" [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include discontinuing use of the affected TOTOLINK T10 firmware version 4.1.8cu.5207, as no known countermeasures or patches are currently available. It is recommended to replace the affected device with an alternative product. Additionally, restricting network access to the device's management interface, implementing firewall rules to block unauthorized HTTP POST requests to /cgi-bin/cstecgi.cgi, and monitoring for exploit attempts can help reduce risk until replacement is possible.
