Cross-account contact information disclosure
Published Jun 6, 2023 · Updated Jan 7, 2025
Information exposure in mbCONNECT24 2.13.3 and earlier allows remote authenticated users to read limited contact data from other accounts. CERT@VDE has not published the affected portal function or the authorization check that fails across mbCONNECT24, mymbCONNECT24, myREX24, and myREX24.virtual. Exploitation requires a remote low-privileged account, and the reported consequence is limited to disclosure of some contact information.
