A Cross Protocol Injection vulnerability exists in Schneider Electric's PowerLogic (PM5560 prior to FW version 2.5.4) product. The vulnerability makes the product susceptible to cross site scripting attack on its web browser. User inputs can be manipulated to cause execution of java script code.
Security readout for executives and security teams
Schneider Electric PowerLogic PM5560 meters running firmware before 2.5.4 have a web-browser input handling flaw. A user could be tricked into interacting with manipulated content that runs JavaScript in the device web context, potentially exposing limited information or altering limited data. Exposure is limited to environments operating Schneider Electric PowerLogic PM5560 devices below firmware 2.5.4, especially where the device web interface is reachable by users or management workstations. Treat as a moderate OT remediation item. It is not described as actively exploited, but affected meters are operational assets, and web-interface flaws can create avoidable risk in industrial environments. Mitigation focus: Upgrade affected PM5560 devices to firmware 2.5.4 or later where applicable.; Review Schneider Electric advisory SEVD-2018-228-01 for vendor-specific guidance.; Limit access to device web management to trusted operational networks..
