CVE-2024-21888 is a high-severity privilege escalation vulnerability affecting Ivanti Connect Secure (versions 9.x and 22.x) and Ivanti Policy Secure (versions 9.x and 22.x). This vulnerability allows a user to elevate privileges to that of an administrator, potentially compromising the integrity and confidentiality of the affected systems.
The CVSS score of 8.8 indicates a significant risk, highlighting the critical nature of this vulnerability. The attack vector is network-based, which means that exploitation does not require physical access to the target system, increasing the urgency for organizations to address this vulnerability.
Risk to organizations includes unauthorized access to sensitive information and systems, potentially leading to further exploitation and data breaches. Given the high severity and potential impact, organizations should prioritize patching immediately.
As of now, there are no known exploits available for this vulnerability. However, organizations must remain vigilant and monitor for any potential updates from Ivanti regarding this issue.
Organizations should stay informed about this vulnerability and ensure that appropriate measures are in place to mitigate the risks.
Vulnerability Details
The vulnerability allows for privilege escalation in the web component of Ivanti Connect Secure and Ivanti Policy Secure. The official description states that it allows a user to elevate privileges to that of an administrator. This can lead to unauthorized access and control over sensitive operations within the affected systems.
The vulnerability has a CVSS score of 8.8, indicating high severity. The attack vector is categorized as NETWORK, with low attack complexity. Privileges required for exploitation are low, and no user interaction is required. The impacts are significant, with high confidentiality, integrity, and availability impacts.
This vulnerability falls under the CWE-269 classification, which pertains to privilege escalation issues.
Technical Analysis
The root cause of this vulnerability lies in insufficient validation of user permissions within the web components of Ivanti Connect Secure and Policy Secure. This allows attackers to exploit the vulnerability and gain elevated privileges.
The attack vector is network-based, meaning that an attacker could exploit this vulnerability remotely without needing physical access to the affected systems. The attack complexity is low, and the required privileges are also low, further increasing the risk of exploitation. No user interaction is required, making it easier for an attacker to successfully exploit this vulnerability.
Exploitation of this vulnerability could lead to significant impacts on confidentiality, integrity, and availability, as attackers may gain unauthorized access to sensitive data and potentially disrupt services.
Risk & Impact Analysis
Organizations using Ivanti Connect Secure and Ivanti Policy Secure are at risk due to this privilege escalation vulnerability. If exploited, attackers could gain administrator-level access, allowing them to manipulate system settings, access sensitive data, and potentially compromise other connected systems.
The potential blast radius is significant, especially for organizations that rely on these components for secure remote access and policy management. Thus, it is crucial for organizations to assess the urgency of this vulnerability based on their deployment context and the potential for exploitation.
Given the high CVSS score and the nature of the vulnerability, organizations should prioritize remediation in their patch management processes.
