Details
A number of the functions in PilotManager pass parameters directly through to the database layer, which then does not do any escaping on the parameters. For example setPilotStatus: https://github.com/DIRACGrid/DIRAC/blob/1738e7c6d2f31d26f1364255d9d2e87b4896c922/src/DIRAC/WorkloadManagementSystem/Service/PilotManagerHandler.py#L343-L349
https://github.com/DIRACGrid/DIRAC/blob/1738e7c6d2f31d26f1364255d9d2e87b4896c922/src/DIRAC/WorkloadManagementSystem/DB/PilotAgentsDB.py#L117
This won't accept multiple statements separated by a semicolon, but a carefully crafted set of parameters containing SQL escapes would likely be able to change or return other database entries.
Further to this, the PilotManager access control is only set to "authenticated"; this allows these functions to be called by any user. This allows any user to manage (e.g. delete, read output of) any pilot pilot job: https://github.com/DIRACGrid/DIRAC/blob/1738e7c6d2f31d26f1364255d9d2e87b4896c922/src/DIRAC/WorkloadManagementSystem/ConfigTemplate.cfg#L111-L118
This is fixed by changing the SQL statements to use proper parameter substitution and providing a suitable set of access rules for the exported pilot management functions.
