Descriptions

Multiple CODESYS Products are prone to a out-of bounds read or write access. A low privileged remote attacker may craft a request with invalid offset, which can cause an out-of-bounds read or write access, resulting in denial-of-service condition or local memory overwrite, which can lead to a change of local files. User interaction is not required.

Diversos productos CODESYS son propensos a un acceso de lectura o escritura fuera de límites. Un atacante remoto poco privilegiado puede diseñar una petición con un desplazamiento no válido, lo que puede causar un acceso de lectura o escritura fuera de límites, resultando en una condición de denegación de servicio o a una sobreescritura de la memoria local, lo que puede conllevar a un cambio de los archivos locales. No es requerida una interacción del usuario
