Summary
This detection rule targets the exploitation of the Baron Samedit vulnerability (CVE-2021-3156), which could allow an attacker to gain root privileges on Linux systems. The rule specifically focuses on identifying the use of the "sudoedit -s \\" command, which is indicative of attempts to leverage this vulnerability. By analyzing logs from Linux environments, the detection alerts when this particular command is executed, as it can signal potential malicious activity aiming to exploit a known weakness in the 'sudo' command. If exploited, this vulnerability can lead to complete system compromise, where an attacker can access sensitive data and potentially cause major breaches. This rule is currently classified as experimental and requires implementation via Splunk Universal Forwarders to collect relevant system logs. While the rule does indicate some known false positives, further investigation and validation need to be undertaken to determine the actual context of any alerts generated.
