Official description
A vulnerability exists in Quick Heal Total Security 23.0.0 in the quarantine management component where insufficient validation of restore paths and improper permission handling allow a low-privileged local user to restore quarantined files into protected system directories. This behavior can be abused by a local attacker to place files in high-privilege locations, potentially leading to privilege escalation.

The underlying weakness: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
