Zoom and Xerox have released urgent security updates to address critical vulnerabilities in their software, including privilege escalation and remote code execution flaws. Learn about the risks, affected systems, and how to protect your organization.

Critical Security Flaws Patched: Zoom and Xerox Fix Privilege Escalation and Remote Code Execution Vulnerabilities

TL;DR

  • Zoom and Xerox have released critical security updates to fix vulnerabilities in their software, including privilege escalation and remote code execution (RCE) flaws.
  • The Zoom vulnerability (CVE-2025-49457) affects Windows clients and has a CVSS score of 9.6, making it highly severe.
  • Users and organizations are strongly advised to update immediately to mitigate potential exploits.

Critical Security Flaws Discovered in Zoom and Xerox Software

Two major technology companies, Zoom and Xerox, have released emergency security updates to address critical vulnerabilities in their software. These vulnerabilities, if exploited, could allow attackers to escalate privileges and execute arbitrary code remotely, posing significant risks to users and organizations.


Zoom Vulnerability: Privilege Escalation Risk in Windows Clients

Overview of the Flaw

Zoom has patched a high-severity vulnerability in its Windows client, identified as CVE-2025-49457. This vulnerability has been assigned a CVSS score of 9.6, indicating its critical nature. The flaw stems from an untrusted search path, which could enable attackers to escalate privileges on a compromised system.

Potential Impact

If successfully exploited, this vulnerability could allow an attacker to:

  • Gain elevated privileges on a victim’s system.
  • Execute malicious code with higher-level permissions.
  • Compromise sensitive data or take control of the affected system.

Affected Systems

  • Zoom Clients for Windows (versions prior to the latest update).

Zoom users are urged to update their software immediately to the latest version to mitigate the risk of exploitation. Organizations should prioritize patching to prevent potential breaches.


Xerox Vulnerability: Remote Code Execution in FreeFlow Core

Overview of the Flaw

Xerox has addressed a critical vulnerability in its FreeFlow Core software. While specific details about the vulnerability are limited, it is reported to allow remote code execution (RCE). This type of flaw is particularly dangerous, as it enables attackers to run arbitrary code on vulnerable systems without physical access.

Potential Impact

Exploitation of this vulnerability could lead to:

  • Unauthorized access to sensitive information.
  • System takeover by malicious actors.
  • Disruption of business operations due to compromised systems.

Affected Systems

  • Xerox FreeFlow Core (versions prior to the latest update).

Xerox customers are advised to apply the latest security patches to protect their systems from potential attacks.


Why These Vulnerabilities Matter

Privilege Escalation and RCE: A Growing Threat

Privilege escalation and remote code execution vulnerabilities are among the most dangerous types of security flaws. They allow attackers to:

  • Bypass security measures and gain unauthorized access.
  • Deploy malware or ransomware across networks.
  • Exfiltrate sensitive data for financial or espionage purposes.

The Importance of Timely Patching

Delays in applying security updates can leave systems exposed to zero-day exploits and targeted attacks. Organizations must adopt a proactive approach to patch management to minimize risks.


How to Protect Your Organization

For Zoom Users

  1. Update Immediately: Ensure all Zoom clients are running the latest version.
  2. Enable Automatic Updates: Configure systems to receive and install updates automatically.
  3. Monitor for Suspicious Activity: Use endpoint detection and response (EDR) tools to identify potential breaches.

For Xerox Users

  1. Apply Security Patches: Update FreeFlow Core to the latest version.
  2. Conduct Regular Audits: Assess systems for vulnerabilities and misconfigurations.
  3. Educate Employees: Train staff on recognizing and reporting security threats.

Conclusion

The recent discoveries of critical vulnerabilities in Zoom and Xerox software highlight the ongoing challenges in cybersecurity. Privilege escalation and remote code execution flaws can have devastating consequences if left unaddressed. By applying updates promptly and adopting best security practices, organizations can significantly reduce their exposure to cyber threats.

As cybercriminals continue to refine their tactics, staying vigilant and proactive in patch management is essential for maintaining a secure digital environment.
