Lifecycle Timeline
3Description
A flaw was found in Hibernate. A remote attacker with low privileges could exploit a second-order SQL injection vulnerability by providing specially crafted, unsanitized non-alphanumeric characters in the ID column when the InlineIdsOrClauseBuilder is used. This could lead to sensitive information disclosure, such as reading system files, and allow for data manipulation or deletion within the application's database, resulting in an application level denial of service.
Analysis
Hibernate's InlineIdsOrClauseBuilder is vulnerable to second-order SQL injection when processing non-alphanumeric characters in ID columns, allowing authenticated attackers to read sensitive data, modify database contents, or cause denial of service. The vulnerability requires low privileges and network access with no user interaction, making it exploitable by remote attackers with valid credentials. …
