CVE-2021-32017 is a critical vulnerability identified in JUMP AMS version 3.6.0.04.009-2487. The vulnerability arises from a SOAP endpoint within the JUMP AMS application that improperly exposes the ability to list the contents of the remote file system. This flaw allows an attacker to enumerate the entire directory and file structure of the server hosting the application. The vulnerability requires low privileges (PR:L), no user interaction (UI:N), and can be exploited remotely over the network (AV:N) with low attack complexity (AC:L). The vulnerability impacts confidentiality, integrity, and availability, as the attacker can gain detailed knowledge of the server’s file system, which can be leveraged for further attacks such as privilege escalation, data exfiltration, or service disruption. The vulnerability has a CVSS v3.1 base score of 9.9, indicating a critical severity level. The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. No known exploits in the wild have been reported yet, and no patches or vendor advisories are currently linked. The vulnerability’s exploitation does not require user interaction but does require some level of privilege, which suggests that an attacker must have some authenticated access or be able to send requests that the SOAP endpoint accepts. The exposure of the full file system structure can facilitate targeted attacks and reconnaissance, increasing the risk of subsequent exploitation of other vulnerabilities or unauthorized access to sensitive files.

For European organizations, this vulnerability poses a significant risk, especially for those using JUMP AMS in critical infrastructure, manufacturing, or enterprise environments where asset management systems are integral. The ability to enumerate the full server file system can lead to exposure of sensitive configuration files, credentials, or intellectual property. This can result in data breaches, operational disruption, and potential compliance violations under GDPR if personal data is exposed. The critical CVSS score reflects the high likelihood of severe impact, including unauthorized data access and potential system compromise. Organizations in sectors such as manufacturing, utilities, and large enterprises that rely on JUMP AMS for asset management are particularly vulnerable. The vulnerability could also be leveraged as a foothold for lateral movement within networks, increasing the risk of widespread compromise. Given the lack of known exploits in the wild, proactive mitigation is essential to prevent exploitation by threat actors who may develop exploits in the future.

1. Immediate mitigation should include restricting access to the vulnerable SOAP endpoint by implementing network-level controls such as firewalls or VPNs to limit access only to trusted internal users. 2. Apply strict authentication and authorization controls on the JUMP AMS SOAP services to ensure only authorized users can access sensitive endpoints. 3. Monitor and audit access logs for unusual or unauthorized requests to the SOAP endpoint to detect potential reconnaissance activity. 4. If possible, disable or remove the vulnerable SOAP endpoint until a vendor patch or update is available. 5. Conduct a thorough review of the server’s file system permissions and harden the operating system to minimize sensitive data exposure. 6. Implement network segmentation to isolate critical asset management systems from general user networks. 7. Engage with the vendor or community to obtain patches or updates addressing this vulnerability as soon as they become available. 8. Educate system administrators and security teams about this vulnerability to ensure rapid detection and response to any exploitation attempts.
