CVE-2020-2675Network attack vector

Unauthorized data access via login flaw

Published Jan 15, 2020 · Updated Sep 30, 2024

Authentication bypass in Oracle Hospitality OPERA 5 Property Services 5.5 allows remote authenticated users to access critical data via HTTP. Oracle identifies the Login component as the affected locus but has not disclosed the specific operation on untrusted input that causes the authorization failure. The attacker must hold low privileges and need not interact with another user; successful exploitation permits broad data read access and some update, insert, or delete actions.
