CVE-2024-24997 is a path traversal vulnerability identified in the web component of Ivanti Avalanche, a widely used endpoint management and software distribution platform. This vulnerability affects versions before 6.4.3 and allows a remote attacker who has valid authentication credentials to exploit improper input validation related to file path handling (classified under CWE-22). By manipulating file paths, the attacker can traverse directories outside the intended scope and execute arbitrary commands on the system with SYSTEM-level privileges, which is the highest level of access on Windows systems. The vulnerability does not require user interaction beyond authentication, making it easier to exploit once credentials are obtained. The CVSS v3.0 score of 8.8 reflects the high impact on confidentiality, integrity, and availability, combined with low attack complexity and no need for user interaction. Although no public exploits have been reported yet, the potential for severe damage is significant, including full system compromise, data theft, and disruption of managed endpoints. Ivanti Avalanche is commonly deployed in enterprise environments for patch management and software deployment, making this vulnerability particularly critical for organizations relying on it to maintain IT infrastructure security and compliance.

For European organizations, the impact of CVE-2024-24997 can be substantial. Ivanti Avalanche is often used in large enterprises, government agencies, and critical infrastructure sectors to manage endpoints and deploy software updates. Exploitation could lead to complete system compromise, enabling attackers to steal sensitive data, disrupt operations, or move laterally within networks. This could result in significant operational downtime, regulatory non-compliance (especially under GDPR), and reputational damage. The ability to execute commands as SYSTEM means attackers can disable security controls, install persistent malware, or exfiltrate data undetected. Given the centralized role of Avalanche in endpoint management, a successful attack could cascade across multiple systems, amplifying the impact. European organizations with complex IT environments and stringent data protection requirements are particularly vulnerable to the consequences of such a compromise.

To mitigate this vulnerability, European organizations should: 1) Immediately upgrade Ivanti Avalanche to version 6.4.3 or later, where the vulnerability is patched. 2) Restrict access to the Avalanche web interface using network segmentation, VPNs, or IP whitelisting to limit exposure to authenticated users only. 3) Enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of credential compromise. 4) Monitor logs and network traffic for unusual activity indicative of exploitation attempts, such as unexpected command executions or directory traversal patterns. 5) Conduct regular security audits and vulnerability scans on the Avalanche deployment. 6) Educate administrators about the risks of path traversal vulnerabilities and the importance of secure credential management. 7) Implement application-layer firewalls or web application firewalls (WAFs) that can detect and block path traversal attempts. 8) Prepare incident response plans specifically addressing potential compromise of endpoint management systems.
