CVE-2025-43948Public exploitNetwork attack vector

Server-side Python execution via entity-filter parameters

Published Apr 22, 2025 · Updated Apr 22, 2025

Python code injection in Codemers KLIMS 1.6.DEV allows remote attackers to execute Python code through crafted entity-filter parameters. The /klims/rest/api/entities/filter endpoint evaluates a supplied sorting value that embeds Python source, allowing the request body to drive server-side execution. The published request includes an Authorization header, but public evidence does not establish whether a valid token is required; successful exploitation reads server files or performs other actions with the service process's privileges.
