Official description

Genexus Protection Server 9.7.2.10 contains an unquoted service path vulnerability in the protsrvservice Windows service configuration. Attackers can exploit the unquoted binary path to execute arbitrary code with elevated LocalSystem privileges by placing malicious executables in specific file system locations.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

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.
