CVE-2025-25231 is a high-severity vulnerability identified in Omnissa Workspace ONE UEM, a unified endpoint management platform widely used for managing enterprise devices and applications. The vulnerability is classified as a Secondary Context Path Traversal issue, which allows an unauthenticated attacker to send specially crafted HTTP GET requests to restricted API endpoints. This flaw enables the attacker to bypass normal access controls and gain unauthorized read-only access to sensitive information stored or managed by the UEM system. The vulnerability affects multiple versions of the product, specifically all versions up to and including 24.10.0.10, 24.6.0.34, 24.2.0.29, and 23.10.0.49. The CVSS v3.1 base score is 7.5, reflecting a high severity due to the network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact is limited to confidentiality, with no direct impact on integrity or availability. Although no known exploits are currently reported in the wild, the vulnerability’s nature and ease of exploitation make it a significant risk. The lack of available patches at the time of publication suggests that organizations must prioritize mitigation and monitoring until official fixes are released. The vulnerability’s exploitation could lead to unauthorized disclosure of sensitive enterprise data, potentially including device configurations, user information, or security policies managed through the UEM platform.

For European organizations, the impact of CVE-2025-25231 could be substantial, especially for those relying on Omnissa Workspace ONE UEM for endpoint management across their IT infrastructure. Unauthorized access to sensitive information could lead to data breaches involving personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Additionally, exposure of device management details could facilitate further targeted attacks or lateral movement within corporate networks. Sectors such as finance, healthcare, and government agencies, which often have stringent compliance requirements and handle sensitive data, are particularly at risk. The vulnerability’s read-only nature limits direct manipulation but still compromises confidentiality, which is critical in these environments. The absence of required authentication and user interaction increases the likelihood of automated scanning and exploitation attempts, raising the urgency for European entities to address this issue promptly.

European organizations should implement the following specific mitigation strategies: 1) Immediate inventory and identification of all Omnissa Workspace ONE UEM instances and their versions to assess exposure. 2) Apply any available vendor patches or updates as soon as they are released; in the absence of patches, consider temporary workarounds such as restricting network access to the UEM API endpoints via firewall rules or VPN segmentation to trusted management networks only. 3) Implement strict monitoring and logging of all API requests to detect anomalous or unauthorized GET requests indicative of exploitation attempts. 4) Employ Web Application Firewalls (WAFs) with custom rules to detect and block path traversal patterns targeting the UEM APIs. 5) Conduct regular security assessments and penetration tests focusing on UEM infrastructure to identify potential exploitation vectors. 6) Educate IT and security teams about this vulnerability to ensure rapid incident response capability. 7) Review and minimize sensitive data exposure through the UEM platform by applying the principle of least privilege and data minimization where feasible.
