Vulnerability Title
Reusable Account Activation and Recovery Tokens Allow Repeated Account Takeover in vulnerability-lookup
来源: CVE Program / CVE List V5
Vulnerability Description
Vulnerability-Lookup contains an
authentication weakness in its account activation and password-recovery
mechanism. Activation and recovery links were generated using stateless
signed tokens containing only the user's login. Although the token
signature and age were validated, the application did not track whether a
token had already been successfully used. As a result, a captured
activation or password-recovery link remained valid for the entire
configured TOKEN_VALIDITY_PERIOD, even after the associated password had been changed.
An attacker who obtains a valid
activation or recovery token could therefore replay it multiple times
during its validity period to set a new password and repeatedly take
control of the affected account. In addition, tokens were not bound to a
specific purpose, allowing the same token mechanism to be used across
activation and recovery workflows. The patch introduces purpose-bound
tokens and a random nonce whose SHA-256 digest is stored with the user
account. The nonce is invalidated after a successful password change,
making tokens single-use, while issuing a new token invalidates any
previously issued token. The password-setting operation now explicitly consumes the token before committing the account change.
Successful exploitation requires
the attacker to obtain a currently valid activation or recovery link,
but does not require knowledge of the victim's existing password or an
authenticated session.
