A privileged attacker in GeoNetwork before 3.12.0 and 4.x before 4.0.4 can use the directory harvester before-script to execute arbitrary OS commands remotely on the hosting infrastructure. A User Administrator or Administrator account is required to perform this. This occurs in the runBeforeScript method in harvesters/src/main/java/org/fao/geonet/kernel/harvest/harvester/localfilesystem/LocalFilesystemHarvester.java. The earliest affected version is 3.4.0.
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
