Exploitation Probability (EPSS)

Low risk
0.32%

23th percentile - higher than 23% of all known CVEs

Summary

PLANKA 2.2.0 through 2.2.1 fails to limit incorrect TOTP codes submitted to POST /api/access-tokens/verify-totp, allowing brute force of two-factor codes. Attackers who know a user's password can reuse the ten-minute pending token to guess codes and obtain a full access token.

Risk Assessment

The risk includes account takeover even with two-factor authentication enabled, potentially leading to unauthorized data access.

Recommendation

Update PLANKA to a version that limits TOTP attempts (e.g., rate limiting and lockout). Additionally, implement log monitoring and alerts for unusual login attempts.
