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?
This vulnerability exists in the UTT 进取 520W 1.7.7-180627 device, specifically in the strcpy function within the /goform/formConfigNoticeConfig file. By manipulating the 'timestart' argument, an attacker can cause a buffer overflow. This vulnerability can be exploited remotely, and the exploit has been publicly disclosed.
How can this vulnerability impact me? :
The buffer overflow vulnerability can allow an attacker to execute arbitrary code remotely, potentially leading to unauthorized access, data corruption, or denial of service on the affected device.
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/formConfigNoticeConfig, specifically looking for abnormal or oversized 'timestart' parameter values that could trigger the buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such suspicious requests. Additionally, you can use tools like curl or wget to manually test the endpoint by sending crafted requests with large 'timestart' parameters to observe if the device behaves unexpectedly or crashes. Example command: curl -X POST http://<device-ip>/goform/formConfigNoticeConfig -d "timestart=$(python3 -c 'print("A"*1000)')" [1, 3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the vulnerable device's management interface from untrusted networks, such as placing it behind a firewall or VPN. Since no vendor patch or fix is available, it is recommended to replace the affected UTT 进取 520W device with a non-vulnerable alternative. Monitoring for exploit attempts and applying network-level protections to block malicious traffic targeting /goform/formConfigNoticeConfig can also help reduce risk. [3]
