The discovery of the regreSSHion vulnerability in OpenSSH on July 1st, 2024, highlighted the panic and chaos among security teams and vendors, emphasizing the importance of understanding Remote Code Execution (RCE) vulnerabilities. These vulnerabilities, allowing attackers to execute code remotely, vary in criticality based on factors like pre-authentication, exploitability, and popularity of affected software. Examples like EternalBlue and regreSSHion, with their pre-auth nature, zero-click exploitable features, and complexity, are particularly alarming
Understanding the criticality factors helps in assessing and mitigating the risks efficiently. The impact, exploit ease, software popularity, patching difficulty, and default configuration play crucial roles. By analyzing cases like EternalBlue and regreSSHion, the article stresses the need for structured responses to critical vulnerabilities, such as asset identification and automated patching, to maintain a strong security posture and protect organizations from potential exploitation. https://www.cyberdefensemagazine.com/regresshion-critical-rce-vulnerabilities-and-when-should-you-be-scared/
