Overview<\/strong><\/p>\n

CVE-2025-46788 is a high-severity vulnerability affecting Zoom Workplace for Linux. This flaw allows unauthorized users to potentially disclose sensitive information via network access due to improper certificate validation. Given the widespread use of Zoom Workplace, particularly in the current remote-working environment, this vulnerability poses a significant risk to enterprises and organizations globally.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-46788
\nSeverity: High (7.4 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system compromise and data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Zoom Workplace for Linux | Prior to 6.4.13<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from improper validation of certificates in Zoom Workplace for Linux. An attacker can exploit this flaw by presenting a forged certificate to the affected application. Due to the lack of proper validation, the application may accept the certificate as genuine, allowing the attacker to achieve a variety of malicious objectives including system compromise and data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Consider the following conceptual example where an attacker presents a forged certificate to the affected application:<\/p>\n

GET \/zoom\/workplace\/certificate HTTP\/1.1\nHost: target.zoom.com\nContent-Type: application\/x-x509-ca-cert\n{ \"forged_certificate\": \"...\" }<\/code><\/pre>\n
In this example, the malicious user sends a GET request to the target’s Zoom Workplace server with a forged certificate. If the target server fails to validate the certificate properly, it may accept it as genuine, enabling the attacker to exploit the system and potentially disclose sensitive information.<\/p>\n
Mitigation<\/strong><\/p>\n
Users are advised to update their Zoom Workplace for Linux to version 6.4.13 or later where this vulnerability has been addressed. In case an immediate update is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. However, these should not be considered as long-term solutions due to their limitations in preventing such attacks.<\/p>\n","protected":false},"excerpt":{"rendered":"
