Summary
Pingvin Share X versions 1.5.0 through 1.18.0 contain a vulnerability that allows an attacker to bypass password verification when managing TOTP settings. The root cause is a missing `await` keyword on calls to asynchronous methods `verifyPassword` and `authenticateUser`. In JavaScript, an unawaited Promise is always truthy, so the logic intended to throw a ForbiddenException when a password is incorrect never executes. The vulnerability is fixed in version 1.18.1.
Risk Assessment
Risk of unauthorized changes to TOTP settings, potentially leading to account takeover or bypass of two-factor authentication.
Recommendation
Update Pingvin Share X to version 1.18.1 or later. If a user is locked out, an administrator must manually reset the user's TOTP status in the database.
Original NVD description (English source)
Pingvin Share X is a secure and easy self-hosted file sharing platform. A vulnerability in versions 1.5.0 through 1.18.0 allow an attacker to bypass password verification when managing Time-based One-Time Password (TOTP) settings. The root cause is a missing `await` keyword on calls to the asynchronous `verifyPassword` method in `authTotp.service.ts` and the `authenticateUser` method in `auth.service.ts`. In JavaScript, an unawaited `Promise` is always truthy. So the logic intended to throw a `ForbiddenException` when a password is incorrect. It never executes because the expression evaluates the existence of the `Promise` object rather than its resolved boolean result. The vulnerability is fixed in version 1.18.1 by ensuring all asynchronous authentication calls are properly awaited. There are no official workarounds. If a user is locked out, an administrator must manually reset the user's TOTP status in the database.
