Prevent admin level from accessing the application specific data belonging to that user when impersonating an account. This permission can be set at the application level by creating a system property specific to the application. These system properties use the **<scope>.impersonateCheck** naming format \(for example **sn\_hr\_core.impersonateCheck**\). Create a system property with a value of **true** to prevent users from accessing the application-specific data belonging to another user when impersonating an account. **Note:** Not all applications are designed to work in this configuration or have a System Properties \[sys\_properties\] record for this purpose. The following scopes are configured to work with this property. - sn\_opp\_market - sn\_jny - sn\_imt\_vaccine - sn\_imt\_health\_test - sn\_hr\_core - sn\_egd\_goals - sn\_egd\_core - sn\_egd\_act - sn\_em - sn\_talent\_aia - sn\_ecn For each application with the **<scope>.impersonateCheck** property in the System Properties \[sys\_properties\] table, ensure the property value is set to **true**. **Note:** These properties can only be modified by the scoped administrator for the specific application. Use this script to identify properties that require updates or creation on the instance: ``` var properties = [ 'sn_opp_market.impersonateCheck', 'sn_jny.impersonateCheck', 'sn_imt_vaccine.impersonateCheck', 'sn_imt_health_test.impersonateCheck', 'sn_hr_core.impersonateCheck', 'sn_egd_goals.impersonateCheck', 'sn_egd_core.impersonateCheck', 'sn_egd_act.impersonateCheck', 'sn_em.impersonateCheck', 'sn_talent_aia.impersonateCheck', 'sn_ecn.impersonateCheck' ]; var pm = new GlidePluginManager(); for (var i = 0; i < properties.length; i++) { var property = properties[i]; var application = property.split('.')[0]; var propertyValue = gs.getProperty(property, 'false'); if (pm.isActive(application) && propertyValue.toLowerCase() != 'true') { gs.print(property); } } ``` ## More information

Security risk - Severity score: 3.8 - CVSS score: Low - A value of **false** for these properties allows an admin level user to impersonate another user and access application data with the impersonated user's access. This may be undesirable or allow for unauthorized data access in specific application contexts.
Functional impact Admin level users aren't be able to impersonate another user and view that user's data in a specific application context.
