Root access gives an attacker or administrator complete control of a Unix-like system, allowing changes to data, software, accounts, and security settings.

Background for this topic.
Root access is unrestricted administrative control of a Unix or Linux system. The root account, or an equivalent privilege obtained through mechanisms such as sudo, can read or change nearly any file, alter system configuration, install software, and control running processes. Related uses of “root” may describe equivalent administrator privileges in containers, cloud workloads, network appliances, or mobile devices.
Because root privileges can bypass ordinary access controls, stolen administrative credentials or a vulnerability that enables privilege escalation can let an attacker modify security settings, access protected data, establish persistence, or disrupt the host. Organizations generally reduce exposure by disabling direct root login where practical, using named administrator accounts with least privilege, protecting privileged authentication with strong controls, and recording and reviewing elevation events. Vulnerability management should prioritize flaws that can grant local or remote root-level execution; during an incident, investigators must assess whether root access was obtained and treat the host’s integrity as potentially compromised.
A maximum-severity security vulnerability impacting LiteSpeed User-End cPanel Plugin has come under active exploitation in the wild
Botnet Operators Execute First Known Exploit of Nearly Decade-Old FlawOperators behind a botnet picked up on a nearly decade-old flaw in Asus routers allowing an unauthenticated attacker to achieve remote code execution as a root user. VulnCheck began observing exploitation of the Asus vulnerability on May 17.
