Sophos Mobile is a comprehensive enterprise mobility management solution that is used by organizations to secure, manage, and control their mobile devices. This software is typically deployed by IT departments within companies to ensure that all mobile devices used in the corporate environment are compliant with security policies, can be remotely managed, and are protected against threats. The on-premises version of Sophos Mobile allows companies to host the solution on their own servers, providing them with complete control over their data and the security of their mobile fleet. It is widely used across various industries due to its robust feature set, including device encryption, threat protection, and application management. The versions affected by CVE-2022-3980 are from 5.0.0 to 9.7.4, highlighting the importance of keeping such critical security infrastructure up to date.

CVE-2022-3980 represents a critical XML External Entity (XXE) vulnerability in Sophos Mobile managed on-premises versions from 5.0.0 to 9.7.4. This vulnerability allows attackers to perform server-side request forgery (SSRF) and potentially execute arbitrary code on the affected system. XXE vulnerabilities occur when an application processes XML input that includes external entity references, leading to unauthorized access to the file system or interaction with internal or external systems. The critical severity of this vulnerability is due to its potential impact on confidentiality, integrity, and availability of the system.

The vulnerability is exploited through malicious XML content sent to the OmaDsServlet endpoint of the Sophos Mobile server. By crafting a specially designed XML document that includes a reference to an external entity, an attacker can cause the server to dereference the external entity. This action could lead to the disclosure of sensitive information stored on the server, server-side request forgery (SSRF) attacks, or even remote code execution. The exploit utilizes the POST method to send the malicious payload to the server, demonstrating the need for strict input validation and processing controls in web applications.

The exploitation of this XXE vulnerability could have severe consequences for affected organizations. Attackers could gain access to sensitive data stored on the server, including personal information of users, corporate data, and credentials. Furthermore, it opens the possibility for SSRF attacks, allowing attackers to interact with internal systems that are normally inaccessible from the external network. In worst-case scenarios, successful exploitation could lead to remote code execution, giving attackers full control over the affected server. The high CVSS score reflects the potential for significant impact on the confidentiality, integrity, and availability of the system.
