Technical details

A SQL injection vulnerability exists in the SearchUserTopUps and SearchAllTopUps functions within model/topup.go. The application fails to escape SQL wildcard characters (such as % and _) in the 'keyword' parameter before concatenating them into a GORM 'LIKE' query. An authenticated remote attacker can provide a complex pattern of wildcards, forcing the database engine to perform expensive combinatorial backtracking. This results in high CPU consumption and exhaustion of database connections, leading to a Denial of Service (DoS). The vulnerability affects the /api/user/topup/self endpoint. No official patch has been released by the vendor as of the disclosure date.
