What is CVE-2023-30801?

The qBittorrent client versions up to 4.5.5 have a significant security flaw due to the usage of default credentials when the web user interface is enabled. The software does not enforce a mandatory change to these default credentials, allowing remote attackers to exploit the vulnerability. By leveraging default credentials, an attacker can authenticate to the web interface and execute arbitrary operating system commands through the 'external program' feature. This vulnerability has been targeted in attacks as early as March 2023, underscoring the urgency for users to secure their installations against unauthorized access.
