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. |

Can you explain this vulnerability to me?
[{'type': 'paragraph', 'content': 'CVE-2026-3015 is a critical buffer overflow vulnerability found in UTT HiPER 810G firmware versions up to 1.7.7-171114. The flaw exists in the strcpy function within the file /goform/formPolicyRouteConf, where improper handling of the input argument "GroupName" allows an attacker to overflow the buffer.'}, {'type': 'paragraph', 'content': 'This happens because the input buffer is copied to an output buffer without verifying that the input size is smaller than the output buffer size, leading to a classic CWE-120 (buffer copy without checking size) vulnerability.'}, {'type': 'paragraph', 'content': 'The vulnerability can be exploited remotely without authentication, making it highly severe. A proof-of-concept exploit is publicly available, demonstrating the ease of exploitation.'}] [1, 3]
How can this vulnerability impact me? :
This vulnerability impacts the confidentiality, integrity, and availability of the affected device.
An attacker can exploit this flaw remotely to execute arbitrary code or cause denial of service (DoS) by overflowing the buffer through the GroupName parameter in the formPolicyRouteConf endpoint.
Because the exploit requires no authentication and is publicly available, the risk of compromise is high.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

How can this vulnerability be detected on my network or system? Can you suggest some commands?
[{'type': 'paragraph', 'content': 'This vulnerability can be detected by monitoring network traffic for suspicious requests targeting the endpoint /goform/formPolicyRouteConf, specifically those manipulating the GroupName parameter with unusually large or malformed input that could trigger a buffer overflow.'}, {'type': 'paragraph', 'content': 'Since the vulnerability involves a buffer overflow via the strcpy function on the GroupName argument, detection can involve inspecting HTTP requests sent to the affected device for abnormal payload sizes or patterns.'}, {'type': 'paragraph', 'content': 'Suggested commands to detect exploitation attempts might include using network packet capture tools such as tcpdump or Wireshark to filter HTTP POST requests to /goform/formPolicyRouteConf, for example:'}, {'type': 'list_item', 'content': "tcpdump -i <interface> -A 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)' | grep '/goform/formPolicyRouteConf'"}, {'type': 'list_item', 'content': 'Using curl or similar tools to test the endpoint with crafted payloads to see if the device responds abnormally or crashes.'}, {'type': 'paragraph', 'content': 'Additionally, reviewing device logs for crashes or abnormal behavior after receiving requests to this endpoint can help detect exploitation attempts.'}] [1, 3]
What immediate steps should I take to mitigate this vulnerability?
There are no known mitigations or countermeasures available for this vulnerability in the affected firmware versions.
The immediate recommended step is to replace the affected product or upgrade the firmware to a version that is not vulnerable, if available.
Until a patch or update is available, restricting remote access to the device, especially blocking access to the /goform/formPolicyRouteConf endpoint, can reduce the risk of exploitation.
Monitoring network traffic for exploitation attempts and isolating affected devices from untrusted networks are also advisable interim measures.
