PHOENIX CONTACT: Remote code execution in CHARX Series
An unauthenticated remote attacker can modify configurations to perform a remote code execution, gain root rights or perform an DoS due to improper input validation.
An unauthenticated remote attacker can modify configurations to perform a remote code execution, gain root rights or perform an DoS due to improper input validation.
An unauthenticated remote attacker can use this vulnerability to change the device configuration due to a file writeable for short time after system startup.
A local attacker with low privileges can use a command injection vulnerability to gain root privileges due to improper input validation using the OCPP Remote service.
A low privileged remote attacker can use a command injection vulnerability in the API which performs remote code execution as the user-app user due to improper input validation. The confidentiality is partly affected.
An unauthenticated remote attacker can write memory out of bounds due to improper input validation in the MQTT stack. The brute force attack is not always successful because of memory randomization.
An unauthenticated remote attacker can perform a command injection in the OCPP Service with limited privileges due to improper input validation.
An unauthenticated remote attacker can upload a arbitrary script file due to improper input validation. The upload destination is fixed and is write only.
