CVE-2024-34519 is a security vulnerability affecting Avantra Server versions 24.x before 24.0.7 and 24.1.x before 24.1.1. The issue arises from improper handling of dashboard security, specifically related to dashboards that utilize an auto-login user configuration. When a dashboard is created with an auto-login user that has elevated privileges, and this dashboard is shared with other users, the access control mechanisms can be bypassed. This bypass allows dashboard visitors to gain access to data and privileges that they should not have, leading to unauthorized data disclosure and potential privilege escalation. The vulnerability is categorized under CWE-289 (Improper Authentication), highlighting that the authentication and access control checks are insufficient. The CVSS 3.1 score of 6.8 reflects a medium severity with network attack vector, high confidentiality and integrity impact, low attack complexity, and requiring low privileges but no user interaction. Although no exploits are currently known in the wild, the vulnerability poses a significant risk to organizations relying on Avantra Server dashboards for monitoring and management. The lack of availability impact means the system remains operational, but sensitive data exposure and unauthorized actions are the primary concerns. The vulnerability was publicly disclosed on May 5, 2024, and fixed in versions 24.0.7 and 24.1.1. Organizations should prioritize patching to prevent potential exploitation.

The primary impact of CVE-2024-34519 is unauthorized data disclosure and privilege escalation within Avantra Server environments. Attackers or malicious insiders with the ability to create dashboards can configure them with auto-login users that have elevated privileges, then share these dashboards to bypass normal access controls. This can lead to exposure of sensitive monitoring data, configuration details, or operational metrics that could be leveraged for further attacks or espionage. The integrity of data viewed through dashboards can also be compromised, potentially misleading operators or causing incorrect operational decisions. Since the vulnerability does not affect availability, systems remain functional, but the confidentiality and integrity risks are significant. Organizations with sensitive operational data or compliance requirements are at higher risk. The medium severity score reflects that exploitation requires some privileges but no user interaction, making it a moderate threat that could be exploited by insiders or attackers who have gained limited access. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future attacks.

To mitigate CVE-2024-34519, organizations should immediately upgrade Avantra Server to versions 24.0.7 or 24.1.1 or later, where the vulnerability has been fixed. Until patching is possible, administrators should audit existing dashboards for any that use auto-login users, especially those shared broadly or with users who should not have elevated privileges. Remove or restrict auto-login configurations to the minimum necessary privilege level. Implement strict role-based access controls (RBAC) to limit who can create or share dashboards with auto-login users. Monitor dashboard creation and sharing activities for unusual patterns or privilege escalations. Additionally, review and tighten authentication and session management policies related to dashboard access. Conduct regular security reviews and penetration testing focused on dashboard and user privilege configurations. Finally, educate users and administrators about the risks of sharing dashboards with auto-login users and enforce policies to prevent misuse.
