CVE-2023-26440

Arbitrary SQL execution via unsanitized registerGroup parameters

Published Aug 2, 2023 · Updated Aug 2, 2024

SQL injection in the OX App Suite office cacheservice 8.10 allows remote attackers on a restricted network to execute arbitrary SQL queries. The registerGroup API accepts insufficiently sanitized SQL syntax in cache-group parameters and later executes it when creating new cache groups. The unauthenticated API is reachable only from a local or restricted network, and successful exploitation can read or modify database data.
