CVE-2022-33185 : What You Need to Know

Brocade Fabric OS versions before v.9.0.1e and v9.1.0 are vulnerable to stack-based buffer overflows due to the use of unsafe string functions in processing user input. This could be exploited by authenticated local attackers to execute arbitrary code as the root user.

Understanding CVE-2022-33185

What is CVE-2022-33185?

CVE-2022-33185 is a vulnerability in Brocade Fabric OS versions before v.9.0.1e and v9.1.0 that allows authenticated local attackers to exploit stack-based buffer overflows, leading to arbitrary code execution with root user privileges.

The Impact of CVE-2022-33185

The impact of this vulnerability is significant as it allows attackers with local access to the affected systems to execute malicious code with elevated privileges, potentially compromising the integrity and confidentiality of the system.

Technical Details of CVE-2022-33185

Vulnerability Description
