Because the system did not record whether a given TOTP period had already been consumed, the same code remained valid for its entire time window (typically 30 seconds). An attacker who captures a legitimate code during a user&#39;s login could replay it to authenticate a second session as that user.</p> <p>Preconditions:</p> <p>- The target user has TOTP-based two-factor authentication enabled.</p> <p>- The attacker is in a position to observe or intercept the TOTP code during a legitimate login (e.g., network-level interception, shoulder surfing, or a compromised client).</p> <p>- The replay must occur within the TOTP validity period.</p> <p>Security impact:</p> <p>- Unauthorized account access by replaying a captured one-time code.</p> <p>- Potential compromise of threat-intelligence data and administrative functions accessible to the targeted user.</p> <p>Affected versions: &lt;v2.5.48.</p> <p><strong>Affected:</strong> MISP</p> <p>MISP contains a vulnerability in its two-factor authentication (TOTP) verification process that permits a valid one-time code to be accepted more than once within its time-based validity window.</p> <p>The issue exists in the user login flow where a TOTP code is verified as a second authentication factor.
