A serious security vulnerability has been uncovered in Apache Atlas, the open-source governance and metadata management tool widely used within Hadoop and enterprise data ecosystems. This flaw, tracked as CVE-2024-46910, could allow malicious actors to execute cross-site scripting (XSS) attacks and potentially impersonate other users, posing a significant risk to data governance and security.
Apache Atlas plays a crucial role in enabling organizations to build data asset catalogs, classify and govern these assets, and foster collaboration among data scientists, analysts, and governance teams. The vulnerability, rated as “important,” directly impacts the integrity and trustworthiness of these processes.
As the official Apache security advisory warns, “An authenticated user can perform XSS and potentially impersonate another user.” This means that an attacker who has already gained legitimate access to an Atlas instance could exploit this flaw to inject malicious scripts into the application. These scripts could then be used to steal user credentials, hijack sessions, or manipulate data, potentially leading to unauthorized access, data breaches, or disruption of governance workflows.
This issue affects Apache Atlas versions 2.3.0 and earlier. Organizations using any of these versions are strongly advised to take immediate action. The recommended solution is a direct upgrade to the newly released version 2.4.0. “Users are recommended to upgrade to version 2.4.0, which fixes the issue,” the advisory states.
XSS vulnerabilities, while sometimes perceived as less severe than other types of attacks, can be highly dangerous in the context of a governance tool like Atlas. The potential for user impersonation adds another layer of risk, as attackers could not only steal data but also manipulate governance policies and classifications, undermining the entire data governance framework.
Given the sensitive nature of the information managed by Apache Atlas, applying this update should be a top priority for all affected organizations. Delaying the upgrade leaves systems vulnerable to exploitation and puts valuable data assets at risk. Upgrading to version 2.4.0 is a crucial step in mitigating the risks associated with this XSS vulnerability and ensuring the continued security and reliability of Apache Atlas deployments.
