A vulnerability has been identified in SICAM PQ Analyzer (All versions < V3.18). A service is started by an unquoted registry entry. As there are spaces in this path, attackers with write privilege to those directories might be able to plant executables that will run in place of the legitimate process. Attackers might achieve persistence on the system ("backdoors") or cause a denial of service.

Make sure these executables do not exist, cannot be created or cannot be executed (e.g. by Group Policy Software Restriction): - C:\Program.* - C:\Program Files.* - C:\Program Files (x86)\Siemens.* - C:\Program Files (x86)\Siemens Energy\SICAM\PQ.* Please note that blocking of e.g. "C:\Program.exe" is not sufficient, as the attacker might be able to plant "C:\Program.com", "C:\Program.msi" or an executable with any other extension there.
