What is CVE-2025-24914?

Recent findings have highlighted a local privilege escalation vulnerability in Nessus that affects versions prior to 10.8.4. When Nessus is installed to a non-default location on a Windows system, the application fails to enforce secure permissions for its sub-directories. This oversight can potentially be exploited by users, leading to unauthorized access and increased privileges in the system if the directories remain unsecured. It is crucial for users installing Nessus to adhere to default installation procedures or to implement strict security measures for custom installation locations to mitigate this risk.
