| CWE ID | Description |
|---|---|
| CWE-77 | The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. |
| CWE-74 | The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. |

Can you explain this vulnerability to me?
CVE-2026-2118 is a command injection vulnerability found in the UTT HiPER 810 router, specifically in firmware version 1.7.4-141218. The flaw exists in the sub_4407D4 function within the rehttpd component, where the Isp_Name parameter is not properly sanitized before being used in a system call. This improper input validation allows an authenticated attacker to execute arbitrary operating system commands with root privileges by sending specially crafted requests to the /goform/formReleaseConnect endpoint.
The vulnerability enables privilege escalation through command injection due to insufficient neutralization of special characters in user input. The attack can be launched remotely and requires authentication.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized execution of arbitrary commands with root privileges on the affected device. This compromises the confidentiality, integrity, and availability of the system.
- An attacker can remotely execute commands, potentially taking full control of the router.
- Confidential information stored or transmitted by the device can be exposed or altered.
- The device’s normal operation can be disrupted, leading to denial of service.
- Because the exploit requires authentication but can be performed remotely, it poses a significant risk in environments where the device is accessible.
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': 'The vulnerability involves command injection via the Isp_Name parameter in requests to the /goform/formReleaseConnect endpoint of the UTT HiPER 810 router. Detection can focus on monitoring for unusual or crafted HTTP requests targeting this endpoint, especially those containing suspicious payloads in the Isp_Name argument.'}, {'type': 'paragraph', 'content': "Since exploitation requires authentication and involves command injection, network detection could include inspecting logs for unexpected commands or anomalies in the router's web service access logs."}, {'type': 'paragraph', 'content': 'Specific commands to detect exploitation attempts are not provided in the available resources.'}] [1, 3]
