CVE-2024-45419: Zoom SDK Information Disclosure Flaw

CVE-2024-45419 Overview

CVE-2024-45419 is an improper input validation vulnerability affecting multiple Zoom applications and SDKs. This flaw allows an unauthenticated attacker to conduct information disclosure via network access. The vulnerability stems from insufficient validation of user-supplied input, which can be exploited remotely without requiring any user interaction or authentication.

Critical Impact

Unauthenticated attackers can exploit this vulnerability over the network to disclose sensitive information from affected Zoom installations, potentially exposing confidential meeting data, user credentials, or other protected content.

Affected Products

• Zoom Meeting Software Development Kit (Android, iOS, Linux, macOS, Windows)
• Zoom Rooms (iPadOS, macOS, Windows)
• Zoom Rooms Controller (Android, Linux, macOS)
• Zoom Video Software Development Kit (Android, iOS, Linux, macOS, Windows)
• Zoom Workplace (Android, iOS)
• Zoom Workplace Desktop (Linux, macOS, Windows)
• Zoom Workplace Virtual Desktop Infrastructure (Windows)

Technical Details for CVE-2024-45419

Vulnerability Analysis

This vulnerability is classified under CWE-252 (Unchecked Return Value), indicating that the affected Zoom applications fail to properly validate input data before processing. The flaw is network-accessible, meaning an attacker can exploit it remotely without requiring local access to the target system. No privileges or user interaction are required for exploitation, making it particularly dangerous in enterprise environments where Zoom is widely deployed.

The vulnerability specifically impacts the confidentiality of information processed by the affected applications. When exploited, attackers can extract sensitive data from the Zoom client or SDK implementation. This could include meeting metadata, participant information, or other confidential data handled by the application.

Root Cause

The root cause of CVE-2024-45419 lies in improper input validation within the affected Zoom applications. Specifically, the vulnerability is associated with CWE-252 (Unchecked Return Value), suggesting that certain return values from input validation functions are not properly checked before the application proceeds with processing user-supplied data. This oversight allows malformed or malicious input to bypass security controls and trigger unintended information disclosure.

Attack Vector

The attack vector for this vulnerability is network-based, allowing remote exploitation without authentication. An attacker can craft specially designed network requests to target affected Zoom applications. The attack requires low complexity to execute and does not depend on any user interaction, making automated exploitation feasible.

The vulnerability allows attackers to send malicious network traffic to a Zoom application endpoint. Due to insufficient input validation, the application processes the malformed input and inadvertently discloses sensitive information in its response. This could be exploited during Zoom sessions, through SDK integrations, or via the Rooms controller interfaces.

Detection Methods for CVE-2024-45419

Indicators of Compromise

• Unusual network traffic patterns to Zoom application endpoints from untrusted sources
• Unexpected data exfiltration or large response payloads from Zoom services
• Anomalous API calls to Zoom SDK components that deviate from normal application behavior
• Log entries showing malformed requests being processed by Zoom applications

Detection Strategies

• Implement network intrusion detection rules to identify malformed requests targeting Zoom applications
• Monitor Zoom application logs for unusual input patterns or error messages related to input handling
• Deploy endpoint detection to identify suspicious process behavior associated with Zoom applications
• Utilize SentinelOne's behavioral AI to detect exploitation attempts targeting Zoom components

Monitoring Recommendations

• Enable detailed logging on all Zoom client applications and SDK implementations
• Monitor network traffic for unusual patterns to/from Zoom-related ports and services
• Implement data loss prevention (DLP) rules to detect potential information exfiltration through Zoom applications
• Regularly audit Zoom application configurations and access controls

How to Mitigate CVE-2024-45419

Immediate Actions Required

• Update all affected Zoom products to the latest patched versions immediately
• Inventory all systems running Zoom Meeting SDK, Video SDK, Rooms, or Workplace applications
• Implement network segmentation to limit exposure of Zoom endpoints to untrusted networks
• Enable enhanced security settings in Zoom administration console

Patch Information

Zoom has released security updates to address this vulnerability. Detailed patch information is available in the Zoom Security Bulletin ZSB-24041. Organizations should prioritize updating all affected Zoom products across all platforms including Windows, macOS, Linux, Android, iOS, and iPadOS deployments.

Workarounds

• Restrict network access to Zoom applications using firewall rules until patches can be applied
• Disable or limit external access to Zoom SDK integrations where possible
• Implement web application firewalls (WAF) to filter potentially malicious requests to Zoom services
• Consider temporarily disabling non-essential Zoom integrations in high-security environments until patches are deployed

# Example: Network restriction for Zoom services (firewall rule)
# Restrict Zoom application access to trusted networks only
iptables -A INPUT -p tcp --dport 8801:8810 -s trusted_network/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8801:8810 -j DROP
