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 exists in the UTT 进取 520W 1.7.7-180627 device, specifically in the strcpy function of the /goform/formPictureUrl file. It occurs due to improper handling of the argument 'importpictureurl', which leads to a buffer overflow. This means that an attacker can send specially crafted input to overflow the buffer, potentially causing unexpected behavior or allowing execution of malicious code. The attack can be launched remotely.
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/formPictureUrl for unusually long or malformed values in the importpictureurl parameter, which may indicate an attempt to exploit the buffer overflow. Network intrusion detection systems (NIDS) can be configured to alert on such suspicious requests. Additionally, manual inspection or use of tools like curl or wget can be used to test the endpoint by sending crafted requests with oversized importpictureurl parameters to observe abnormal behavior or crashes. Example command to test the endpoint: curl -X POST http://<target-ip>/goform/formPictureUrl -d "importpictureurl=$(python3 -c 'print("A"*1000)')" [2, 3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the vulnerable device from untrusted networks, such as placing it behind a firewall or VPN, to prevent remote exploitation. Since no patches or vendor mitigations are available, consider disabling the affected service or endpoint if possible. Monitoring for exploit attempts and preparing to replace the affected product with a secure alternative is recommended. Applying network-level protections and limiting exposure are critical until a fix is available. [2]
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability impacts the confidentiality, integrity, and availability of the affected system, which could lead to non-compliance with standards and regulations such as GDPR and HIPAA that require protection of sensitive data and system integrity. However, no specific information about compliance impact or regulatory consequences is provided in the available resources. [2]
How can this vulnerability impact me? :
The vulnerability can allow a remote attacker to exploit the buffer overflow to execute arbitrary code or cause a denial of service on the affected device. This can lead to unauthorized access, disruption of service, or compromise of the device's integrity and availability.
