CVE-2021-42064Network attack vector

Database exposure via unescaped oversized IN clause

Published Dec 14, 2021 · Updated Aug 4, 2024

SQL injection in SAP Commerce 1905, 2005, 2011, and 2105 allows attackers to expose an Oracle backend database. FlexibleSearch fails to escape values when it reconstructs a parameterized IN clause containing more than 1,000 entries. Exploitation requires an Oracle-backed deployment and a platform or extension query that passes partly untrusted input through that oversized clause.
