Buffer Overflow Vulnerability in Zoom Apps Affects User Security

CVE-2024-45421

What is CVE-2024-45421?

CVE-2024-45421 is a buffer overflow vulnerability found in certain Zoom applications, developed by Zoom Communications, Inc. These applications are widely used for communication and collaboration purposes. Should an authenticated user exploit this vulnerability, it may lead to unauthorized privilege escalation via network access, potentially compromising user security and organizational integrity.

Technical Details

This vulnerability arises from a buffer overflow in Zoom Apps, meaning that certain data inputs can exceed allocated memory space, corrupting nearby memory and allowing attackers to manipulate system behavior. The flaw specifically allows already-authenticated users to launch attacks within the network environment, leading to elevated privileges that could grant them greater access to the system and its data.

Potential Impact of CVE-2024-45421

1. Unauthorized Privilege Escalation: Exploiting this vulnerability may enable an authenticated user to gain elevated permissions, potentially accessing sensitive information or critical functionalities without proper authorization.

2. User Data Compromise: The ability to escalate privileges could lead to significant risks regarding user data, allowing attackers to manipulate, extract, or delete sensitive information from the system.

3. Increased Attack Surface: The presence of this vulnerability expands the attack surface, potentially allowing attackers to launch further attacks or deploy malicious software, impacting overall system security and stability.
