Name of the Vulnerable Software and Affected Versions
MISP versions prior to 2.5.48
Description
A flaw in the two-factor authentication (TOTP) verification process allows a valid one-time code to be accepted multiple times within its time-based validity window, typically 30 seconds. This occurs because the system fails to record if a specific TOTP period has already been consumed. An attacker who intercepts a legitimate code during a user login can replay it to establish an unauthorized second session as that user, potentially compromising administrative functions and threat-intelligence data.
Recommendations
Update to version 2.5.48 or later.
