Dangling Database Cursor ('Cursor Injection')

If a database cursor is not closed properly, then it could become accessible to other users while retaining the same privileges that were originally assigned, leaving the cursor "dangling."


Description

For example, an improper dangling cursor could arise from unhandled exceptions. The impact of the issue depends on the cursor's role, but SQL injection attacks are commonly possible.

Background

A cursor is a feature in Oracle PL/SQL and other languages that provides a handle for executing and accessing the results of SQL queries.
