In XStream before version 1.4.16, there is a vulnerability which may allow a remote attacker who has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16. ## Affected - `oncommand_insight` - `activemq < 5.15.14` - `activemq = 5.16.0` - `activemq = 5.16.1` - `jmeter < 5.5` - `xstream < 1.4.16` - `debian_linux = 9.0` - `debian_linux = 10.0` - `debian_linux = 11.0` - `fedora = 33` - `fedora = 34` - `fedora = 35` - `banking_enterprise_default_management = 2.10.0` - `banking_enterprise_default_management = 2.12.0` - `banking_platform = 2.4.0` - `banking_platform = 2.7.1` - `banking_platform = 2.9.0` - `banking_platform = 2.12.0` - `banking_virtual_account_management = 14.2.0` - `banking_virtual_account_management = 14.3.0` - `banking_virtual_account_management = 14.5.0` - `business_activity_monitoring = 11.1.1.9.0` - `business_activity_monitoring = 12.2.1.3.0` - `business_activity_monitoring = 12.2.1.4.0` - `communications_billing_and_revenue_management_elastic_charging_engine = 12.0.0.3.0` - `communications_policy_management = 12.5.0` - `communications_unified_inventory_management = 7.3.2` - `communications_unified_inventory_management = 7.3.4` - `communications_unified_inventory_management = 7.3.5` - `communications_unified_inventory_management = 7.4.0` - `communications_unified_inventory_management = 7.4.1` - `peoplesoft_enterprise_peopletools = 8.58` - `peoplesoft_enterprise_peopletools = 8.59` - `retail_xstore_point_of_service = 16.0.6` - `retail_xstore_point_of_service = 17.0.4` - `retail_xstore_point_of_service = 18.0.3` - `retail_xstore_point_of_service = 19.0.2` - `webcenter_portal = 11.1.1.9.0` - `webcenter_portal = 12.2.1.3.0` - `webcenter_portal = 12.2.1.4.0` ## Remediation Upgrade past the affected range: - `activemq 5.15.14` - `jmeter 5.5` - `xstream 1.4.16`
