AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-70231 is a critical vulnerability in the D-Link DIR-513 router version 1.10. It occurs when processing POST requests related to verification codes at the endpoint /goform/formLogin. The vulnerability arises because the router fails to properly filter the FILECODE parameter in the /goform/getAuthCode endpoint, leading to a path traversal issue.
Additionally, there is a stack buffer overflow vulnerability related to the handling of the curTime parameter in the /goform/formLogin endpoint. Sending a specially crafted POST request with an excessively long curTime value can trigger this overflow via the sprintf function, potentially allowing arbitrary code execution or denial of service.
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized access and control over the affected router. The path traversal issue may allow attackers to access sensitive files or directories outside the intended scope.
The stack buffer overflow can be exploited to execute arbitrary code or cause a denial of service, potentially disrupting network connectivity or allowing attackers to take control of the device.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
