This vulnerability stems from improper input validation within the SQL Server, which enables unauthorized attackers to potentially disclose sensitive information over a network. Such a breach could allow attackers to access confidential data, harming the integrity and confidentiality of organizational information and potentially leading to serious ramifications for affected businesses, including regulatory penalties and reputational damage.
