Cisco ThousandEyes Virtual Appliance Authenticated Web Interface Command Injection Vulnerability
Cisco patched an authenticated command injection in ThousandEyes Virtual Appliance allowing arbitrary OS command execution with root privileges.
Improper validation of user-supplied input in the web-based management interface of Cisco ThousandEyes Virtual Appliance enables command injection. An authenticated remote attacker with valid administrative credentials can save configuration details containing malicious values to execute arbitrary operating system commands with root privileges. Cisco has released software updates that address the vulnerability.
Redtail Payload Analysis [Guest Diary], (Wed, Sep 9th)
SANS guest analyst detonated a RedTail Linux sample from a DShield honeypot, finding process masquerading as php-fpm, monitoring-kill behavior, and a TCP listener.
A DShield honeypot captured multi-architecture RedTail Linux executables (ARM, ARM64, i686, RISC-V, x86-64) deployed via shell scripts. Dynamic analysis of the UPX-packed, statically linked x86-64 sample (SHA-256 63be5f38...d35e) in an isolated Ubuntu 24.04 VM on Proxmox showed it renamed its process via prctl(PR_SET_NAME), killed a filesystem-monitoring process, and opened a TCP listening socket while surviving processes posed as php-fpm or PostgreSQL-like workers. Differential memory images pre- and post-execution were captured from the hypervisor for forensics.
