CVE-2021-43084Network attack vector

Database manipulation via tableName SQL injection

Published Mar 24, 2022 · Updated Aug 4, 2024

SQL injection in Dreamer CMS 4.0.0 allows remote attackers to alter database queries through the tableName parameter. Public records identify tableName as the untrusted input but do not disclose the receiving endpoint, code locus, or exact operation that incorporates it into an SQL statement. Network access without authentication is sufficient; successful injection permits database reads, writes, or service interruption, while the exact query context remains undisclosed.
