Technical ContextAI · show details
This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. pyLoad is a free and open-source Download Manager. The folder /.pyload/scripts has scripts which are run when certain actions are completed, for e.g. a download is finished. By downloading a executable file to a folder in /scripts and performing the respective action, remote code execution can be achieved in versions prior to 0.5.0b3.dev87. A file can be downloaded to such a folder by changing the download folder to a folder in /scripts path and using the /flashgot API to download the file. This vulnerability allows an attacker with access to change the settings on a pyload server to execute arbitrary code and completely compromise the system. Version 0.5.0b3.dev87 fixes this issue. Affected products include: Pyload. Version information: prior to 0.5.0.

What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
OS command injection occurs when an application passes unsanitized user input directly into system shell commands.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
