An issue was discovered in B&R Industrial Automation APROL before R4.2 V7.08. An attacker can get access to sensitive information outside the working directory via Directory Traversal attacks against AprolSqlServer, a different vulnerability than CVE-2019-16357.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
