Apache Unomi is an open-source customer data platform that individuals and organizations use to manage customer data, build profiles, and personalize user experiences. It is deployed as a servlet on Java application servers, typically in environments requiring customer data management and user interaction analytics. Companies leverage Apache Unomi to enhance marketing strategies by personalizing user experiences through gathered data. The platform is essential for businesses aiming to understand customer behaviors through data-driven insights, facilitating customized interactions. Apache Unomi's integration capabilities with various customer relationship management (CRM) systems make it a pivotal component in managing extensive customer databases. It is widely utilized in business intelligence processes to shape consumer engagement strategies and improve service delivery.
The detected vulnerability, Remote Code Execution (RCE), allows attackers to execute arbitrary code within vulnerable applications. This occurs through input fields or parameters exposed to the user, which the application processes without adequate validation. Exploiting this vulnerability can lead to hostile code execution within the application's hosting environment. In Apache Unomi, this issue arises from inadequate validation of OGNL scripting, allowing unsanctioned calls to Java classes. This makes it possible for attackers to perform harmful operations on affected systems. RCE vulnerabilities pose significant security risks, potentially granting attackers full control over compromised systems.
Apache Unomi's vulnerability lies in its use of OGNL scripting within user-defined conditions, enabling attackers to inject and execute arbitrary Java code. The vulnerable endpoint is '/context.json', susceptible due to improper sanitization of inputs handled through the 'Content-Type: application/json' header. Malicious scripts can leverage the 'parameterValues' within user conditions to trigger unwanted executions. This occurs when unsanitized input fields embed OGNL syntax, leading to Java class executions. The primary vulnerable parameter is 'propertyName' under conditions, which orchestrates execution when influenced by malicious payloads. The template's approach includes manipulating this parameter to craft scenarios that simulate potential attacks.
Exploitation of this vulnerability can lead to severe impacts, including unauthorized execution of destructive operations or full system compromise. A successful attack allows adversaries to manipulate system operations, hamper data integrity, or potentially expose sensitive information. Such breaches compromise the confidentiality, integrity, and availability of affected systems. Moreover, they can facilitate lateral movements within networks, exacerbating the damage. If leveraged by attackers, these vulnerabilities could enable persistence within the network, endangering not only isolated systems but broader organizational infrastructures. System administrators face significant operational disruptions and potential financial loses if left unmitigated.
