Weak SSH Password in IDC SFX2100 Enables Remote Unauthorized Access

Executive Summary

This vulnerability affects the International Datacasting Corporation (IDC) SFX2100 Satellite Receiver. It involves a trivial password set for the 'user' (usr) account, which allows a remote unauthenticated attacker to gain unauthorized SSH access to the system.

Although the attacker is initially dropped into a restricted shell, they can easily spawn a complete pseudo-terminal (pty) to obtain a fully interactive shell, thereby gaining greater control over the system.

Impact Analysis

This vulnerability can have a severe impact as it allows an attacker to remotely access the system without authentication.

Once access is gained, the attacker can escalate from a restricted shell to a fully interactive shell, potentially allowing them to execute arbitrary commands, manipulate system settings, or disrupt normal operations.

Given the high CVSS score of 9.2, this vulnerability poses a critical security risk.
