CVE-2024-39527

Summary

An Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the command-line interface (CLI) of Juniper Networks Junos OS on SRX Series devices allows a local, low-privileged user with access to the Junos CLI to view the contents of protected files on the file system.

Through the execution of crafted CLI commands, a user with limited permissions (e.g., a low privilege login class user) can access protected files that should not be accessible to the user. These files may contain sensitive information that can be used to cause further impact to the system.

This issue affects Junos OS on SRX Series: 

  • All versions before 21.4R3-S8, 
  • 22.2 before 22.2R3-S5, 
  • 22.3 before 22.3R3-S4, 
  • 22.4 before 22.4R3-S4, 
  • 23.2 before 23.2R2-S2, 
  • 23.4 before 23.4R2.
