What it is

⚠️ A sneak peek into sensitive data is easier than you think! A crafty user can exploit file permission issues on the vCenter Server, accessing information they shouldn't be able to. 🤔 Think of it like a library where the staff forgot to lock up some reference books. A visitor without a library card could just stroll in and see all the exclusive information—yikes! An attacker with non-administrative access could unearth sensitive information, potentially leading to data breaches or revealing internal processes. This information leak can be absolutely devastating for your organization and can compromise your security posture.

Put simply

Think of it like a library where the staff forgot to lock up some reference books. A visitor without a library card could just stroll in and see all the exclusive information—yikes! This information disclosure vulnerability allows a malicious actor with limited privileges to access files they normally shouldn't, due to improper file permissions within the vCenter Server.

What to do

An attacker with non-administrative access could unearth sensitive information, potentially leading to data breaches or revealing internal processes. This information leak can be absolutely devastating for your organization and can compromise your security posture. It's time to patch up! Update to the latest version of the vCenter Server to address this issue. Additionally, review and tighten file permissions to ensure sensitive data is secure. You've got this! Stay vigilant and follow these steps to lock down your server. 🛡️
