Unauthenticated user enumeration via login timing discrepancy
Published Sep 14, 2022 · Updated Sep 17, 2024
User enumeration in mbCONNECT24, mymbCONNECT24, myREX24, and myREX24.virtual 2.11.2 and earlier allows remote attackers to identify valid accounts. The authentication web service processes submitted usernames with response-time differences that disclose whether each account exists. No authentication or user interaction is required; the disclosed account names support targeted password attacks, but no data modification or service interruption is reported.
