CVE-2023-4849Network attack vector

Authenticated SQL injection via trash deletion fids

Published Sep 9, 2023 · Updated Sep 26, 2024

SQL injection in IBOS OA 4.5.5 allows remote authenticated users to alter database queries through the file-trash fids parameter. The file dashboard's trash deletion handler processes the attacker-controlled fids value without effective SQL neutralization. A valid low-privilege session is required, while public material does not identify the reachable statements or database records.
