Low-privilege file reads and log clearing via injection
Published May 7, 2025 · Updated Feb 26, 2026
Command injection in Cisco IOS XE Software with the web interface enabled allows remote authenticated users to read limited files or clear logs. The web interface fails to validate crafted input before passing it to an operating-system command, enabling limited file reads or clearing of syslog and licensing logs. A low-privileged account is sufficient; exposure requires HTTP or HTTPS management with active session modules, and impact is limited to file disclosure and log integrity.
