Critical · published April 30, 2020
CVSS calls it critical at 9.8. It is confirmed in active exploitation. It sits in the 99.9th percentile for exploit probability.
🚨 A remote user can run arbitrary commands without any authentication in SaltStack Salt versions before 2019.2.4 and 3000.2! 😱 Think of it like a restaurant where the front door is wide open, allowing anyone to walk in and change the menu or access the chef's secret recipes without a reservation. That’s essentially what’s happening here — unauthorized access to sensitive functions! An attacker could exploit this vulnerability to access user tokens and execute commands on connected salt minions, effectively taking control of your entire infrastructure! The potential for data breaches, unauthorized changes, or even service disruptions is absolutely devastating! 🔥
Think of it like a restaurant where the front door is wide open, allowing anyone to walk in and change the menu or access the chef's secret recipes without a reservation. That’s essentially what’s happening here — unauthorized access to sensitive functions! This vulnerability arises from the salt-master process's ClearFuncs class, which fails to properly validate method calls, allowing remote users to bypass authentication and access restricted functionalities.
An attacker could exploit this vulnerability to access user tokens and execute commands on connected salt minions, effectively taking control of your entire infrastructure! The potential for data breaches, unauthorized changes, or even service disruptions is absolutely devastating! 🔥 To protect your system, immediately upgrade to SaltStack Salt version 2019.2.4 or 3000.2. Additionally, review and tighten access controls to prevent unauthorized method calls in the meantime. 🛡️ You've got this! With these updates, you'll be stepping into the security hero spotlight in no time! 🌟
