CVE-2024-24999 is a path traversal vulnerability identified in the web component of Ivanti Avalanche, a widely used endpoint management and patching solution. The flaw exists in versions prior to 6.4.3 and allows a remote attacker who has authenticated access to the system to perform arbitrary command execution with SYSTEM-level privileges. The root cause is improper sanitization of file path inputs, classified under CWE-22, which enables attackers to traverse directories beyond intended boundaries and execute commands on the host operating system. This vulnerability is particularly dangerous because it grants the highest level of privilege (SYSTEM), allowing full control over the affected system, including the ability to manipulate data, disrupt services, or pivot within a network. The attack vector is network-based with low attack complexity, requiring no user interaction but necessitating valid credentials, which could be obtained through phishing, credential reuse, or insider threats. Although no active exploits have been reported in the wild, the high CVSS score (8.8) reflects the critical nature of the vulnerability. Ivanti Avalanche is commonly deployed in enterprise environments for managing large fleets of devices, making the impact of exploitation potentially widespread. The vulnerability was publicly disclosed on April 19, 2024, with no official patch links provided at the time, emphasizing the need for vigilance and immediate remediation once updates are available.

For European organizations, exploitation of CVE-2024-24999 could lead to full system compromise of Ivanti Avalanche servers, which are often central to endpoint management and patch deployment. This could result in unauthorized access to sensitive data, disruption of IT operations, and potential lateral movement within corporate networks. Critical sectors such as finance, healthcare, manufacturing, and government agencies that rely on Ivanti Avalanche for managing endpoints are at heightened risk. The SYSTEM-level command execution capability means attackers could disable security controls, deploy malware, or exfiltrate data undetected. Given the centralized role of Avalanche in patch management, attackers could also manipulate patch deployments, introducing further vulnerabilities or backdoors. The requirement for authenticated access somewhat limits exposure but does not eliminate risk, especially in environments with weak credential policies or where credentials have been compromised. The absence of known exploits in the wild provides a window for proactive defense, but the high severity score indicates that successful exploitation would have severe consequences.

1. Upgrade Ivanti Avalanche to version 6.4.3 or later immediately once the patch is available to remediate the vulnerability. 2. Enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of credential compromise. 3. Restrict access to the Avalanche web interface to trusted networks and IP addresses using network segmentation and firewall rules. 4. Monitor authentication logs and system activity for unusual access patterns or command executions indicative of exploitation attempts. 5. Conduct regular credential audits and enforce strong password policies to minimize the risk of unauthorized access. 6. Implement least privilege principles for users accessing Avalanche, limiting administrative rights where possible. 7. Prepare incident response plans specifically addressing potential compromise of management infrastructure. 8. Stay informed through vendor advisories and threat intelligence feeds for updates on exploit availability and additional mitigations.
