AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2020-37204 is a denial of service vulnerability in RemShutdown version 2.9.0.0 and earlier. It occurs because the application does not properly validate the size of input in the registration key field, leading to a buffer overflow.
An attacker can exploit this by generating a specially crafted payload of 1000 characters and pasting it into the registration key input, which causes the application to crash.
How can this vulnerability impact me? :
This vulnerability can cause the RemShutdown application to crash, resulting in a denial of service condition.
Since the attack requires local access and user interaction, an attacker with local access can disrupt the availability of the application by triggering this crash.
The impact is limited to availability, with no direct impact on confidentiality or integrity.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
