      "title": "Junos OS: Low-privileged user can cause script to run as root, leading to privilege escalation",
      "summary": "An Incorrect Permission Assignment for Critical Resource vulnerability in line card script processing of Juniper Networks Junos OS allows a local, low-privileged user to install scripts to be executed as root, leading to privilege escalation.\n\nA local user with access to the local file system can copy a script to the router in a way that will be executed as root, as the system boots. Execution of the script as root can lead to privilege escalation, potentially providing the adversary complete control of the system.\n\nThis issue only affects specific line cards, such as the MPC10, MPC11, LC4800, LC9600, MX304-LMIC16, SRX4700, and EX9200-15C.\n\nThis issue affects Junos OS:  *  from 23.2 before 23.2R2-S4, \n  *  from 23.4 before 23.4R2-S5, \n  *  from 24.2 before 24.2R2-S1, \n  *  from 24.4 before 24.4R1-S3, 24.4R2.\n\n\n\n\n\n\nThis issue does not affect versions prior to 23.1R2.",
