Detailed vulnerability description
The vulnerability allows a remote attacker to bypass share protection and access protected shared resources.
The vulnerability exists due to improper access control in the POST /de2api/share/proxyInfo endpoint when handling share password or ticket validation requests. A remote attacker can send a request with a protected share UUID and invalid or empty password or ticket values to bypass share protection and access protected shared resources.
The issue occurs because the X-DE-LINK-TOKEN is generated and returned before password or ticket validation is completed.
