The specific details of the vulnerability are not provided in the source, but the potential impact could be significant. An attacker could exploit this weakness to inject malicious SQL code into database queries, potentially allowing them to bypass security measures and gain unauthorized access to sensitive information stored within the Exim database, or even modify the data. This could lead to confidentiality breaches, data corruption, or even complete system compromise.
