Summary
An OS command injection vulnerability in the CLI of Juniper Networks Junos OS allows a local, low privileged attacker to take complete control of the device. A specific 'request csds' command doesn't sanitize user provided input so that it can be interpreted as a command. This allows unintended command execution with root privileges, which can lead to unauthorized system access or modification. This issue affects Junos OS: • 24.4 versions before 24.4R2-S4; • 25.2 versions before 25.2R2-S1; • 25.4 versions before 25.4R1-S3; This issue does not affect Junos OS releases before 24.4R1.
