Doc Text:	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.

Description OSIDB Bzimport 2026-01-05 13:16:50 UTC

I found a second order SQL Injection that I think is interesting enough to report.
On line 27 of Hibernate's InlineIdsOrClauseBuilder, the value we put into the Id column will be reused unsanitized. We do have to activate it as described here: https://in.relation.to/2017/02/01/non-temporary-table-bulk-id-strategies/#inlineidsorclausebulkidstrategy. If the user is able to set their own ids and those ids allow non-alphanumeric characters (My POC needs these: {, }, :, \", \', =) and they are using InlineIdsOrClauseBuilder then the Application is vulnerable to attack. I have provided hibernate-poc-2.zip with a vulnerable hibernate application along with 2 python scripts as POCs. In my POCs I am able to delete all items in the table with a simple id (see hibernate-poc-attack1.py in the zip), and with a slightly more complicated Id I am able to read the first 100 characters of from the

/etc/passwd


file (see hibernate-poc-attack2.py in the zip).

As documented in Hibernate’s official blog regarding the InlineIdsOrClauseBulkIdStrategy https://in.relation.to/2017/02/01/non-temporary-table-bulk-id-strategies/#inlineidsorclausebulkidstrategy http://subwaycity.org
 - enabling this strategy causes identifier values to be inlined directly into generated SQL. If user-controlled identifiers containing non-alphanumeric characters are persisted and later reused, this may result in a second-order SQL injection condition.
