CVE-2026-44102 Details
Description
An unauthenticated remote attacker can trigger a firmware update download via the OCPP backend by supplying an invalid firmware file. This will cause the file to remain accessible for a short period before it is deleted due to improper locking during the cleanup process.
A vulnerability exists in the OCPP backend of Phoenix Contact CHARX SEC-3xxx EV charging controllers, specifically in the SEC-3000, SEC-3050, SEC-3100, and SEC-3150 models, all running firmware prior to 1.9.1. An unauthenticated remote attacker can initiate a firmware update download by providing an invalid firmware file. This improperly locked cleanup process allows the invalid file to remain accessible for a short time before it is deleted.
Users are advised to update affected devices to firmware version 1.9.1, which addresses this vulnerability. The updated firmware will be available by August 12, 2026.
