Linux Under Attack! CISA Raises Alarm Over Active Exploitation of Privilege Elevation Flaw

2 min read
Linux users warned by CISA about active exploit of a privilege elevation flaw called "Baron Samedit", highlighting the importance of system cybersecurity and immediate patching.


The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning concerning the active exploitation of a critical Linux privilege elevation flaw. This recent development underlines the need for individuals and businesses to remain vigilant and continually protect their systems.

This privilege elevation flaw, tagged as CVE-2021-3156, exists in a program known as sudo, which stands for ‘superuser do.’ This program, built into most UNIX and UNIX-based systems like Linux, gives certain users the ability to execute commands with administrative privileges. However, a bug within the sudo program is currently being exploited by malicious actors to gain unauthorized system control.

The flaw, also named “Baron Samedit” by the team who discovered it, enables an unauthorized user to gain root-level access to a system, thereby increasing the level of a potential threat significantly.

The association with BleepingComputer comes from the computer site being one of the first to report on this vulnerability. As such, users would-be wise to heed the alerts given by platforms like BleepingComputer and urgently apply patches released by their respective Linux distributors to safeguard their systems.


While Linux is often touted as a more secure alternative to other operating systems, the active exploitation of the sudo flaw serves as a reminder that no system is immune to threats. Urgency and adherence to security protocols are vital. Remember, stay safe, stay updated, and keep an eye on our blog for the latest cybersecurity updates.
