A newly discovered vulnerability in Ivanti’s security products could allow attackers to execute remote code, posing a significant risk to corporate networks. The flaw affects Ivanti Connect Secure, Ivanti Policy Secure, and ZTA Gateways—widely used solutions for secure remote access and network access control. If exploited, this vulnerability could enable cybercriminals to install malicious programs, manipulate sensitive data, or even take over entire systems.
Ivanti has confirmed that certain versions of its products, including older Pulse Connect Secure appliances, have already been targeted. Organizations using affected versions must act swiftly to apply patches and implement security best practices to mitigate the risk of exploitation.
the Ivanti Vulnerability
What is the Issue?
A vulnerability has been found in Ivanti’s security solutions, including:
– Ivanti Connect Secure (ICS) – A widely used SSL VPN for secure remote access.
– Ivanti Policy Secure (IPS) – A network access control (NAC) solution.
– Ivanti Neurons for Zero Trust Access (ZTA) Gateway – A zero-trust access solution.
What’s the Risk?
The vulnerability (CVE-2025-22457) is a stack-based buffer overflow that allows remote unauthenticated attackers to execute arbitrary code on vulnerable systems. If exploited, attackers could:
– Install malware.
– Steal or modify sensitive data.
– Gain administrative control over affected networks.
Who is Affected?
Organizations using the following Ivanti products:
- Pulse Connect Secure 9.1R18.9 and prior (End of Support).
– Ivanti Connect Secure 22.7R2.5 and prior.
– Ivanti Policy Secure 22.7R1.3 and prior.
– ZTA Gateways 22.8R2 and prior.
Are Attacks Already Happening?
Yes. Ivanti has reported that some customers have already been compromised, particularly those using older, unpatched versions of the affected products.
Recommended Actions
To mitigate the risk, organizations should:
– Apply security patches immediately.
- Implement vulnerability management processes and perform regular security assessments.
- Use automated patch management for quick deployment of security updates.
- Conduct penetration testing to identify weaknesses before attackers do.
- Enforce the principle of least privilege to limit user access rights.
– Ensure network segmentation to isolate critical assets.
What Undercode Says:
Why This Vulnerability is a Big Deal
Ivanti’s security products are widely used in enterprises, making this vulnerability a serious concern. Remote code execution (RCE) flaws are among the most dangerous cybersecurity threats, as they allow attackers to execute commands without needing prior access.
Potential Impact on Organizations
- Enterprise networks are at risk – Since Ivanti’s solutions are often used for secure remote access, a compromised system could become an entry point for attackers.
- Data breaches could occur – Attackers could exfiltrate sensitive corporate information.
- Service disruptions are possible – Hackers could install ransomware or delete critical data, leading to operational downtime.
Lessons from Past Exploits
We’ve seen similar vulnerabilities in the past, like those affecting Citrix ADC and Fortinet VPNs, which led to widespread cyberattacks. Threat actors, including state-sponsored groups, often exploit such flaws quickly. If history is any indicator, organizations that delay patching could be the next victims.
How Organizations Should Respond
- Patch immediately – This cannot be stressed enough. Delaying patches increases the risk of exploitation.
- Enhance security monitoring – Deploy intrusion detection systems (IDS) to identify suspicious activity.
- Harden remote access policies – Enforce multi-factor authentication (MFA) and restrict access to critical systems.
- Conduct a security audit – If you’re running an affected version, assume compromise and check for unauthorized access.
What If You Can’t Patch Right Away?
If immediate patching isn’t possible, consider these temporary measures:
– Restrict network access to vulnerable systems.
– Increase monitoring for unusual behavior.
- Use Web Application Firewalls (WAF) to mitigate potential attacks.
Final Thoughts
This Ivanti vulnerability is a wake-up call for organizations relying on outdated security appliances. Given that real-world attacks are already happening, proactive defense measures are crucial. Companies must treat cybersecurity as an ongoing process—not a one-time fix.
Fact Checker Results:
- Confirmed Exploitation: Ivanti has acknowledged that some customers have already been targeted.
- Severity of Risk: Remote code execution vulnerabilities are critical, as they allow attackers to take full control of systems.
- Mitigation is Possible: Organizations can protect themselves through immediate patching, network segmentation, and security monitoring.
