CVE-2025-8297: CWE-434 Unrestricted Upload of File with Dangerous Type in Ivanti Avalanche
Incomplete restriction of configuration in Ivanti Avalanche before version 6.4.8.8008 allows a remote authenticated attacker with admin privileges to achieve remote code execution
AI Analysis
Technical Summary
CVE-2025-8297 is a vulnerability identified in Ivanti Avalanche, a widely used endpoint management and software deployment platform. The issue arises due to incomplete restrictions on file uploads, specifically allowing an authenticated attacker with administrative privileges to upload files of dangerous types without proper validation or sanitization. This vulnerability is classified under CWE-434, which involves the unrestricted upload of files that can lead to execution of malicious code. By exploiting this flaw, an attacker can achieve remote code execution (RCE) on the server hosting Ivanti Avalanche, potentially gaining full control over the system. The vulnerability requires the attacker to have admin-level credentials, which implies that initial access must be obtained through other means such as credential theft or insider threat. The CVSS v3.1 score of 7.2 reflects a high severity rating, with attack vector being network-based, low attack complexity, and no user interaction needed. The impact includes full compromise of confidentiality, integrity, and availability of the affected system. Although no exploits are currently known in the wild, the vulnerability poses a significant risk due to the critical nature of the Ivanti Avalanche platform in enterprise environments. The lack of patch links suggests that a fix may be pending or recently released, emphasizing the need for vigilance and prompt remediation once available.
Potential Impact
The vulnerability allows remote code execution on Ivanti Avalanche servers, which can lead to complete system compromise. Organizations relying on Avalanche for endpoint management, software distribution, and patch management could face severe disruptions, including unauthorized access to sensitive data, deployment of malicious software, and potential lateral movement within corporate networks. The compromise of Avalanche servers could undermine the security posture of entire IT environments, as attackers may manipulate software deployments or disable security controls. Given the administrative privileges required, the threat is particularly concerning in environments where admin credentials are shared or insufficiently protected. The availability of the platform could also be impacted, causing operational downtime and affecting business continuity. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency for remediation, as proof-of-concept exploits could emerge rapidly. The impact extends globally, especially to organizations in sectors such as government, finance, healthcare, and critical infrastructure that depend on Ivanti Avalanche for secure endpoint management.
Mitigation Recommendations
Organizations should immediately verify their Ivanti Avalanche version and upgrade to version 6.4.8.8008 or later once the patch is released. Until a patch is applied, restrict administrative access to the Avalanche platform using network segmentation, VPNs, and strong multi-factor authentication to reduce the risk of credential compromise. Implement strict file upload policies and monitor for any unusual file upload activity or attempts to upload executable or script files. Conduct regular audits of admin accounts and their activities to detect potential misuse. Employ endpoint detection and response (EDR) solutions to identify anomalous behavior indicative of exploitation attempts. Additionally, consider deploying web application firewalls (WAFs) with custom rules to block suspicious file uploads targeting the Avalanche server. Maintain comprehensive backups of Avalanche configurations and data to enable rapid recovery in case of compromise. Finally, educate administrators on the risks of credential sharing and phishing attacks that could lead to initial access.
