# Oracle E-Business Suite HRMS: US Payroll Year End flaw allows data read and change

A flaw in the US Payroll Year End component of Oracle HRMS (E-Business Suite) lets a low-privileged user with network access alter or delete some HRMS data and read a subset of it. Exploitation requires a person other than the attacker to interact with the system, and the scope change means other products may be affected.

_Summary, check and fix written by a model from the sources; labelled as such._
