LogicalDoc before 8.3.3 allows SQL Injection. LogicalDoc populates the list of available documents by querying the database. This list could be filtered by modifying some of the parameters. Some of them are not properly sanitized which could allow an authenticated attacker to perform arbitrary queries to the database.
LogicalDoc before 8.3.3 could allow an attacker to upload arbitrary files, leading to command execution or retrieval of data from the database. LogicalDoc provides a functionality to add documents. Those documents could then be used for multiple tasks, such as version control, shared among users, applying tags, etc. This functionality could be abused by an unauthenticated attacker to upload an arbitrary file in a restricted folder. This would lead to the executions of malicious commands with root privileges.
