CyberRota Analysis
AI-GeneratedThe mv, cp, and rm utilities in the ExtremeXOS shell environment are vulnerable due to improper path canonicalization, allowing attackers with low-privilege CLI access to exploit symbolic links to access and manipulate sensitive files outside their authorized boundaries. This vulnerability could lead to unauthorized root-level access and persistent modifications to the device's software stack. Organizations using ExtremeXOS should prioritize addressing this issue to mitigate potential security risks from both remote and local attackers.

Original NVD Description
The mv, cp, and rm file utilities exposed within the ExtremeXOS (EXOS) shell environment fail to safely canonicalize paths and follow symbolic links outside of the intended privilege boundary. An attacker with low-privilege CLI access can create a symbolic link that references a privileged filesystem location and then invoke the affected utilities to read, modify, or replace security-critical files outside of their authorized scope. Under certain conditions, this may enable escalation to root-level access and persistent modification of the device software stack. Exploitation is possible remotely by an attacker holding a low-privilege account, or locally via the serial console.
