## Technical details

A command injection vulnerability (CWE-78) exists in multiple Lenovo Personal Cloud Storage models, including the T1, A1, X1, T2, and A1s series. The flaw allows a remote authenticated attacker on the same local network to execute arbitrary OS commands on the device. This is caused by improper neutralization of special elements used in an OS command. While the vulnerability requires authentication, the impact is high as it allows for full system compromise. Notably, Lenovo has declared these specific models as End of Life (EOL) and has stated they will no longer receive security firmware updates, meaning no official patch is expected.
