We advice you to follow the instructions, to resolve
directory traversal (read)
with a
high potential for exploitation
in component FI-LOC-SAF.
According to SAP Security Advisory team a workaround does not exist. It is advisable to implement the correction as monthly patch process .
Missing authority checks are still the most common security defect related to authorizations in custom code. Since SAP uses an explicit authorization model, an authority checks must be coded in order to be executed. If an explicit check is not coded, all users have access. This type of vulnerability not only exists in SAP standard it also exists in customer coding. Check your custom developments for vulnerabilities that pose a risk to your systems. SecurityBridge helps detect code vulnerabilities before they are implemented in production.
Risk specification
SAF-T Framework Transaction SAFTN_G allows an authenticated attacker to exploit insufficient validation of path information provided by users, leading to full server directory access. The attacker can read the whole filesystem structure but cannot overwrite, delete, or corrupt arbitrary files on the server.Solution
The F4 search help of field 'Field Name' in transaction 'SAFTN_G' is removed. The end-user is still able to enter the full path manually or a physical path needs to be assigned. Please check additional comments of the SAP Security Note for details.
