Broken Access Control can occur under the /api/v1/registration/validateEmail endpoint, the /api/v1/vdeskintegration/user/adduser endpoint, and the /api/v1/registration/changePasswordUser endpoint. The web application is affected by flaws in authorization logic, through which a malicious user (with no privileges) is able to perform privilege escalation to the administrator role, and steal the accounts of any users on the system.

An issue was discovered in LIVEBOX Collaboration vDesk through v018. A Bypass of Two-Factor Authentication can occur under the /api/v1/vdeskintegration/challenge endpoint. Because only the client-side verifies whether a check was successful, an attacker can modify the response, and fool the application into concluding that the TOTP was correct.

An issue was discovered in LIVEBOX Collaboration vDesk through v018. A Bypass of Two-Factor Authentication for SAML Users can occur under the /login/backup_code endpoint and the /api/v1/vdeskintegration/challenge endpoint.

An issue was discovered in LIVEBOX Collaboration vDesk through v018. Broken Access Control exists under the /api/v1/vdeskintegration/saml/user/createorupdate endpoint, the /settings/guest-settings endpoint, the /settings/samlusers-settings endpoint, and the /settings/users-settings endpoint.

An issue was discovered in LIVEBOX Collaboration vDesk through v031. An Observable Response Discrepancy can occur under the /api/v1/vdeskintegration/user/isenableuser endpoint, the /api/v1/sharedsearch?search={NAME]+{SURNAME] endpoint, and the /login endpoint. The web application provides different responses to incoming requests in a way that reveals internal state information to an unauthorized actor outside of the intended control sphere.

An issue was discovered in LIVEBOX Collaboration vDesk through v018. An Insecure Direct Object Reference can occur under the 5.6.5-3/doc/{ID-FILE]/c/{N]/{C]/websocket endpoint. A malicious unauthenticated user can access cached files in the OnlyOffice backend of other users by guessing the file ID of a target file.

An issue was discovered in LIVEBOX Collaboration vDesk through v018. Broken Access Control exists under the /api/v1/vdesk_{DOMAIN]/export endpoint. A malicious user, authenticated to the product without any specific privilege, can use the API for exporting information about all users of the system (an operation intended to only be available to the system administrator).

An issue was discovered in LIVEBOX Collaboration vDesk through v018. A Bypass of Two-Factor Authentication can occur under the /login/backup_code endpoint and the /api/v1/vdeskintegration/createbackupcodes endpoint, because the application allows a user to generate or regenerate the backup codes before checking the TOTP.

An issue was discovered in LIVEBOX Collaboration vDesk through v018. A Cryptographic Issue can occur under the /api/v1/vencrypt/decrypt/file endpoint. A malicious user, logged into a victim's account, is able to decipher a file without knowing the key set by the user.

An issue was discovered in LIVEBOX Collaboration vDesk through v018. Stored Cross-site Scripting (XSS) can occur under the /api/v1/getbodyfile endpoint via the uri parameter. The web application (through its vShare functionality section) doesn't properly check parameters, sent in HTTP requests as input, before saving them on the server. In addition, crafted JavaScript content can then be reflected back to the end user and executed by the web browser.

An issue was discovered in LIVEBOX Collaboration vDesk through v031. A URL Redirection to an Untrusted Site (Open Redirect) can occur under the /api/v1/notification/createnotification endpoint, allowing an authenticated user to send an arbitrary push notification to any other user of the system. This push notification can include an (invisible) clickable link.

An issue was discovered in LIVEBOX Collaboration vDesk through v031. A basic XSS vulnerability exists under the /api/v1/vdeskintegration/todo/createorupdate endpoint via the title parameter and /dashboard/reminders. A remote user (authenticated to the product) can store arbitrary HTML code in the reminder section title in order to corrupt the web page (for example, by creating phishing sections to exfiltrate victims' credentials).
