CVE-2025-22457 is a critical vulnerability affecting Ivanti's Connect Secure, Policy Secure, and Zero Trust Access Gateways. The vulnerability stems from a stack-based buffer overflow, which allows a remote unauthenticated attacker to achieve remote code execution. With a CVSS score of 9.0, this vulnerability poses a significant threat to organizations using affected versions of these products.
The severity of this vulnerability is underscored by its exploitability status; it has been confirmed that exploits are available in the wild, highlighting the urgency for organizations to address this issue promptly. Given the potential impact, organizations should prioritize patching immediately.
The risk to organizations includes unauthorized access to sensitive data and disruption of services, making this vulnerability particularly concerning for enterprises that rely on Ivanti's solutions. Organizations need to understand their exposure and take the necessary steps to remediate.
The vulnerability was published on April 3, 2025, and is classified as a critical vulnerability due to its high CVSS score and the availability of exploits. Organizations must take immediate action to protect their systems from potential attacks leveraging this vulnerability.
Vulnerability Details
This vulnerability allows a remote unauthenticated attacker to execute arbitrary code due to a stack-based buffer overflow in Ivanti Connect Secure prior to version 22.7R2.6, Ivanti Policy Secure before version 22.7R1.4, and Ivanti ZTA Gateways prior to version 22.8R2.2. Organizations running these versions are at risk of being exploited.
The vulnerability is classified under CWE-121 (Stack-based Buffer Overflow) and CWE-787 (Out-of-bounds Write). It highlights the need for organizations to implement robust coding practices to mitigate such vulnerabilities.
The CVSS vector for this vulnerability is AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H, indicating that it can be exploited over the network with high attack complexity, requires no privileges, and does not require user interaction, while significantly impacting confidentiality, integrity, and availability.
Technical Analysis
The root cause of CVE-2025-22457 is a flaw in the processing of input data, which allows attackers to manipulate the stack memory. The attack vector is network-based, meaning an attacker does not need physical access to the system to exploit this vulnerability.
The attack complexity is categorized as high, indicating that successful exploitation may require a series of conditions to be met. Importantly, the attacker does not need any privileges, nor do they need user interaction.
In terms of impact, the vulnerability can lead to high confidentiality, integrity, and availability impact, essentially allowing attackers to take control of affected systems, exfiltrate sensitive information, or cause disruptions.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant. Organizations utilizing Ivanti's Connect Secure, Policy Secure, or ZTA Gateways need to assess their exposure and take immediate action to patch or mitigate the vulnerability.
Given the critical nature of this vulnerability, organizations should understand the potential blast radius, which could extend across networks relying on affected Ivanti products. The urgency assessment based on the CVSS score and known exploitation status indicates that this should be treated as a top priority for remediation.
Organizations should prioritize patching immediately. The availability of public exploits increases the risk of rapid exploitation. In addition, the known ransomware campaigns utilizing this vulnerability necessitate immediate attention.
Exploitation Status
