A vulnerability in XStream versions prior to 1.4.17 may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types is affected. The vulnerability is patched in version 1.4.17. ## Affected - `xstream < 1.4.17` - `debian_linux = 9.0` - `debian_linux = 10.0` - `debian_linux = 11.0` - `fedora = 33` - `fedora = 34` - `fedora = 35` - `snapmanager` - `banking_cash_management = 14.2` - `banking_cash_management = 14.3` - `banking_cash_management = 14.5` - `banking_corporate_lending_process_management = 14.2.0` - `banking_corporate_lending_process_management = 14.3.0` - `banking_corporate_lending_process_management = 14.5.0` - `banking_credit_facilities_process_management = 14.2.0` - `banking_credit_facilities_process_management = 14.3.0` - `banking_credit_facilities_process_management = 14.5.0` - `banking_supply_chain_finance = 14.2.0` - `banking_trade_finance_process_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_brm_-_elastic_charging_engine = 11.3` - `communications_brm_-_elastic_charging_engine = 12.0` - `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` - `communications_unified_inventory_management = 7.4.2` - `enterprise_manager_ops_center = 12.4.0.0` - `retail_customer_insights = 15.0.2` - `retail_customer_insights = 16.0.2` - `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` - `retail_xstore_point_of_service = 20.0.1` - `webcenter_portal = 12.2.1.3.0` - `webcenter_portal = 12.2.1.4.0` - `webcenter_sites = 12.2.1.3.0` - `webcenter_sites = 12.2.1.4.0` ## Remediation Upgrade past the affected range: - `xstream 1.4.17`
