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-2026-3699 is a critical buffer overflow vulnerability found in UTT HiPER 810G firmware versions up to 1.7.7-171114.
The flaw exists in the function strcpy within the file /goform/formRemoteControl, where input is copied to a buffer without verifying that the input size is smaller than the destination buffer, leading to a classic CWE-120 (buffer overflow) issue.
This vulnerability allows remote attackers to exploit the device without local access or physical interaction.
The attack complexity is low, making exploitation relatively easy, and a proof-of-concept exploit is publicly available.
How can this vulnerability impact me? :
This vulnerability can compromise the confidentiality, integrity, and availability of the affected system.
An attacker can remotely exploit the buffer overflow to execute denial of service attacks or potentially other malicious actions by overwriting memory.
Since the exploit is publicly available and the attack complexity is low, the risk of successful attacks is high.
No known mitigations or countermeasures have been identified, so the affected product should be replaced to avoid risk.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
I don't know
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring network traffic for requests sent to the endpoint /goform/formRemoteControl, as this is where the buffer overflow occurs.
Since the vulnerability involves exploitation of the strcpy function without bounds checking, detection can involve checking for unusually long or malformed HTTP requests targeting this endpoint.
Specific commands are not provided in the available resources, but network administrators can use tools like tcpdump or Wireshark to capture and analyze HTTP requests to /goform/formRemoteControl for suspicious payloads.
What immediate steps should I take to mitigate this vulnerability?
No known mitigations or countermeasures have been identified for this vulnerability.
It is suggested to replace the affected product with an alternative to avoid risk.
