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 is a buffer overflow issue in the UGREEN DH2100+ device up to version 5.3.0.251125. It affects the function handler_file_backup_create in the /v1/file/backup/create component of the nas_svr module. By manipulating the argument 'path', an attacker can cause a buffer overflow. This attack can be performed remotely, and an exploit is publicly available.
How can this vulnerability impact me? :
The vulnerability can lead to a buffer overflow, which may allow an attacker to execute arbitrary code, cause denial of service, or compromise the confidentiality, integrity, and availability of the affected system. Since the attack can be executed remotely and an exploit is publicly available, it poses a significant security risk.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability impacts the confidentiality, integrity, and availability of the UGREEN DH2100+ NAS device, which could lead to unauthorized access or data breaches. Such impacts can negatively affect compliance with common standards and regulations like GDPR and HIPAA that require protection of sensitive data and system integrity. However, no specific compliance implications or regulatory references are detailed in the provided resources. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection can focus on monitoring requests to the endpoint /v1/file/backup/create on the UGREEN DH2100+ NAS device, especially those manipulating the 'path' argument. Since exploitation requires authentication and involves sending specially crafted payloads that cause buffer overflow, network IDS/IPS rules could be created to flag unusually large or malformed requests to this endpoint. However, no specific detection commands or signatures are provided in the available resources. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the vulnerable NAS device, especially limiting network exposure of the /v1/file/backup/create endpoint. Since no patches or vendor responses are available, consider disabling the nas_svr service if possible or replacing the affected product. Monitoring for exploitation attempts and applying network-level protections such as firewalls or intrusion prevention systems to block suspicious traffic targeting this endpoint is also recommended.
