StudyMD 0.3.2 – Persistent Cross-Site Scripting

The software allows you to store payloads within your flash card manager, as well as upload files (.md) once the malicious code is entered, the payload will be executed immediately. The attacker can send a malicious file with the payload, when this file is opened, the chain will be executed successfully giving access to the remote attacker to get remote execution on the computer.

Mitigation:

Input validation should be used to prevent malicious code from being executed. The application should also be configured to only accept certain file types and reject any other type of file.
