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-2025-15431 is a critical buffer overflow vulnerability in the UTT 进取 512W device, version 1.7.7-171114. It occurs in the strcpy function within the /goform/formFtpServerDirConfig file, where the 'filename' argument is copied into a buffer without checking if the input size fits the buffer. This improper handling leads to a buffer overflow condition, allowing an attacker to potentially compromise the system remotely. The vulnerability is easy to exploit, and a proof-of-concept exploit is publicly available. [1, 3]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing remote attackers to execute a buffer overflow attack, which can compromise the confidentiality, integrity, and availability of the affected system. Potential impacts include denial of service (DoS) and other malicious actions that could disrupt or take control of the device. Since the exploit is publicly available and easy to perform, the risk is critical, and no known mitigations or vendor responses exist. [1, 3]
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/formFtpServerDirConfig on UTT 进取 512W devices running version 1.7.7-171114. Detection involves looking for suspicious or unusually long 'filename' parameters in requests to this endpoint that could trigger the buffer overflow. Since the exploit is publicly available, network intrusion detection systems (NIDS) can be configured with signatures to detect such exploit attempts. Specific commands are not provided in the resources, but monitoring HTTP traffic for POST requests to /goform/formFtpServerDirConfig with abnormal payload sizes or patterns is recommended. [1, 3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected UTT 进取 512W device with an alternative product, as no vendor patches or countermeasures are currently available. Additionally, restricting or blocking remote access to the /goform/formFtpServerDirConfig endpoint, implementing network-level protections such as firewalls or intrusion prevention systems to detect and block exploit attempts, and monitoring network traffic for suspicious activity targeting this vulnerability are advised. [1]
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows remote exploitation leading to buffer overflow, which can compromise confidentiality, integrity, and availability of the affected system. Such compromises can result in violations of data protection and security requirements mandated by standards like GDPR and HIPAA. However, no specific compliance impacts or regulatory considerations are detailed in the provided resources. [1, 3]
