CVE 설명
MISP contains a race condition in the email-based one-time password (OTP) login flow. When two HTTP requests carrying the same valid OTP are submitted concurrently, both can successfully authenticate and establish a session. The root cause is that the OTP value is read from the shared store, validated, and then deleted in separate non-atomic steps, allowing a second in-flight request to read the same value before the first request's deletion takes effect.
Preconditions:
- The target MISP instance has email OTP login enabled.
- The attacker possesses a valid, unexpired OTP (e.g., via email interception or social engineering).
- The attacker can issue two HTTP POST requests in close temporal proximity.
Impact:
- The one-time-use guarantee of the OTP is violated; a single code can yield two authenticated sessions.
- This weakens the authentication control and may facilitate unauthorized access if the OTP is shared or intercepted.
Affected versions: <2.5.48

관련 약점
| 약점 이름 | 출처 | |
|---|---|---|
| Concurrent Execution using Shared Resource with Improper Synchronization The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. |
||
| Time-of-check Time-of-use (TOCTOU) Race Condition The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. |
