SQL injection vulnerability in the Upgrade/Downgrade component (DBMS_UPGRADE_INTERNAL) for Oracle Database 10.1.0.5 allows remote authenticated users to execute arbitrary SQL commands via unknown vectors, aka DB07. NOTE: as of 20070424, Oracle has not disputed reliable claims that DB07 is actually for multiple issues.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
