Official description
In SAP Business One application when a service is created, the executable path contains spaces and isn’t enclosed within quotes, leading to a vulnerability known as Unquoted Service Path which allows a user to gain SYSTEM privileges. If the service is exploited by adversaries, it can be used to gain privileged permissions on a system or network leading to high impact on Confidentiality, Integrity, and Availability.

The underlying weakness: Unquoted Search Path or Element
The product uses a search path that contains an unquoted element, in which the element contains whitespace or other separators. This can cause the product to access resources in a parent path.
How developers prevent this class of flaw
- Properly quote the full search path before executing a program on the system.
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
