T1552.001 Credentials In Files Credential Access
Adversaries may search local file systems and remote file shares for files containing insecurely stored credentials.
T1078.001 Default Accounts Stealth
Adversaries may obtain and abuse credentials of a default account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.
T1059.008 Network Device CLI Execution
Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.
Why these techniques?

Vulnerability exposes hard-coded Telnet credentials in publicly accessible HTTP file (/squashfs-root/web_cste/cgi-bin/product.ini) without authentication, enabling unsecured credential collection from files (T1552.001), valid default account access to Telnet service (T1078.001), and network device CLI execution via Telnet (T1059.008).
