Description

Symptom

The card application component contains a vulnerability through which a malicious user can potentially write arbitrary files on the remote server, possibly corrupting data or altering system behavior.

Solution

Import the relevant Support Package for your release.

For more information and instructions, see Note 1497003. Before you can implement this note, you must have implemented the corrections from Note 1497003.

  • Logical file CARD_CONSISTENCY_CHECK maps to BCA_CARD_TEST_FILE.
  • Logical file CARD_TRANSFER_FILE maps to BCA_CARD_TEST_FILE.
  • Logical file CCPP_CONSISTENCY_CHECK maps to BCA_CARD_ORDER_TEST_FILE.
  • Logical file path BCA_AM_CONSISTENT_PATH is used for BCA_CARD_TEST_FILE and BCA_CARD_ORDER_TEST_FILE.

Reason and prerequisites

The card application component fails to correctly validate the path to which a user-submitted file is written. As a result, a malicious user can potentially overwrite data in the remote system.
