Description

Symptom

A malicious user can exploit BW-BCT-ISR-PIP (test report /RTF/TEST_KTRF) and use specially crafted inputs to modify database commands, resulting in the retrieval of additional information persisted by the system.

Solution

Implement the correction as described in the correction instructions.

After applying the correction, the test report /RTF/TEST_KTRF will exit immediately without any further processing. If you want to use this functionality further, copy the report and modify it according to your needs.

Reason and prerequisites
