SAP security note 1509794, "Directory Traversal in transactions CL6E and CL6F". Below are the symptom and the SAP recommended solution.
Description
Symptom
Transactions CL6E and CL6F contain a vulnerability that allows a malicious user to potentially read arbitrary files on the remote server, potentially disclosing confidential information.
Solution
- Ensure that the corrections contained in Note 1512352 are implemented in your system.
- Follow the correction instructions provided in this note as per the advance correction guidelines.
- Refer to Note 1497003 for additional information. Program changes from this note are also required as a prerequisite.
- Logical file names have been created to validate physical file names:
DIN_CLASSfor transaction CL6E (logical path nameDIN_CLASS_PATH), andDIN_CHARACTERISTICfor transaction CL6F (logical path nameDIN_CHARACTERISTIC_PATH).
Reason and prerequisites
Transactions CL6E and CL6F fail to correctly validate the path used to reference a file read from the remote server. This vulnerability allows an attacker to point the program to an arbitrary file on the system, disclosing its contents.
