Missing Authorization Check in RFC Enabled Function /BDL/_READ_LOG


Impact on Business

A remote authenticated attacker can read log messages and specific fields, such as usernames, from the application server. This has a low impact on the confidentiality of the system and its business applications.


Vulnerability Details

The remote-enabled function module /BDL/_READ_LOG allows authenticated users to read log messages and sensitive fields from the application server without performing sufficient authorization checks. An attacker could exploit this to gather information such as SUSER names and other system log data.
