CVE-2024-46937Public exploitNetwork attack vector

Unauthenticated token data disclosure via serial enumeration

Published Sep 16, 2024 · Updated Oct 24, 2024

Authorization bypass in MFASOFT Secure Authentication Server 1.8.x through 1.9.x before 1.9.040924 allows remote attackers to read user token data. The /api-selfportal/get-info-token-properties endpoint accepts a caller-controlled serial value and returns matching token properties without an authorization check. Unauthenticated network access is sufficient, but discovering valid records requires enumeration of predictable identifiers such as GA00001.
