The wpShopGermany IT-RECHT KANZLEI WordPress plugin before 2.4 does not generate its API authentication token securely, deriving it from data the requester controls and creating it as a side effect of the check that is supposed to validate it, allowing unauthenticated attackers to predict the token and use the access it grants to write arbitrary files, leading to remote code execution.
AnalysisAI
Unauthenticated remote code execution in the wpShopGermany IT-RECHT KANZLEI WordPress plugin affects every release from 1.6 up to but not including 2.4. The plugin builds its API authentication token from data the requester supplies and creates that token as a side effect of the routine that is supposed to validate it, so an attacker can compute a valid token without any credentials and use the access it grants to write arbitrary files on the server, which in a PHP/WordPress context converts directly into code execution. …
