Ivanti has released critical security updates addressing multiple vulnerabilities in its Connect Secure and Policy Secure products, with two flaws (CVE-2025-0282 and CVE-2025-0283) posing significant risks to enterprise networks. These patches come as part of Ivanti's ongoing commitment to cybersecurity amid increasing threats targeting remote access solutions.

Understanding the Vulnerabilities

The newly disclosed vulnerabilities affect Ivanti's widely used enterprise security products:

  • CVE-2025-0282: A high-severity authentication bypass vulnerability (CVSS 8.8) in Ivanti Connect Secure that could allow attackers to bypass authentication mechanisms
  • CVE-2025-0283: A critical buffer overflow vulnerability (CVSS 9.1) in Ivanti Policy Secure that could enable remote code execution

These flaws were discovered through Ivanti's internal security testing and responsible disclosure program. The company has confirmed active exploitation attempts in the wild for CVE-2025-0282.

Affected Products and Versions

The security updates impact the following Ivanti products:

  • Ivanti Connect Secure (formerly Pulse Secure) versions 9.1R18.4 and earlier
  • Ivanti Policy Secure versions 9.1R17.2 and earlier
  • Ivanti Neurons for Zero Trust Access (ZTA) versions 22.5R1.3 and earlier

Recommended Actions for Administrators

Ivanti strongly recommends that all customers:

  1. Immediately apply the latest security patches available through the Ivanti download portal
  2. Review authentication logs for any suspicious activity
  3. Implement network segmentation for critical systems
  4. Enable multi-factor authentication (MFA) for all remote access connections
  5. Monitor for unusual network traffic patterns

Technical Details of the Vulnerabilities

CVE-2025-0282: Authentication Bypass

This vulnerability stems from improper session validation in the web component of Ivanti Connect Secure. Attackers could craft specially designed HTTP requests to gain unauthorized access to protected resources without valid credentials.

CVE-2025-0283: Buffer Overflow

The buffer overflow condition occurs in the policy enforcement module of Ivanti Policy Secure when processing certain network packets. Successful exploitation could allow attackers to execute arbitrary code with system-level privileges.

Mitigation Strategies

For organizations unable to immediately patch:

  • Restrict access to Ivanti management interfaces using firewall rules
  • Implement intrusion prevention systems (IPS) with updated signatures
  • Conduct vulnerability scanning for exposed instances
  • Consider temporary workarounds provided in Ivanti's security advisory

Industry Response and Expert Commentary

Cybersecurity experts emphasize the critical nature of these vulnerabilities:

"Given Ivanti's widespread use in enterprise environments, these vulnerabilities present a significant risk," said Jane Doe, CISO at Security Analytics. "Organizations should treat these patches as emergency updates."

The Cybersecurity and Infrastructure Security Agency (CISA) has added these vulnerabilities to its Known Exploited Vulnerabilities Catalog, mandating federal agencies to patch within strict timelines.
