Summary
by MITRE
An issue was discovered in the Infosysta "In-App & Desktop Notifications" app before 1.6.14_J8 for Jira. It is possible to obtain a list of all Jira projects without authentication/authorization via the plugins/servlet/nfj/ProjectFilter?searchQuery= URI.

This vulnerability exists in the Infosysta "In-App & Desktop Notifications" plugin for Jira, specifically affecting versions prior to 1.6.14_J8. The issue represents a critical information disclosure flaw that allows unauthenticated attackers to enumerate all Jira projects through a specific servlet endpoint. The vulnerability stems from insufficient access controls and authentication checks within the plugin's notification filtering mechanism, which exposes sensitive project information to any user who can access the affected URI path. This misconfiguration creates a significant security risk as it provides attackers with comprehensive visibility into the organization's Jira project landscape without requiring any credentials or authorization.
The technical exploitation of this vulnerability occurs through the plugins/servlet/nfj/ProjectFilter?searchQuery= endpoint, which is designed to filter projects for notification purposes but fails to implement proper authentication verification. Attackers can simply make HTTP requests to this URI without any authentication tokens or session management, thereby bypassing the normal access controls that should restrict project visibility to authorized users only. This flaw directly violates the principle of least privilege and demonstrates a classic case of insecure direct object reference vulnerability where the application exposes internal resource references without proper access validation. The vulnerability is categorized under CWE-284, which addresses improper access control issues, and aligns with ATT&CK technique T1087.001 for account discovery through enumeration of accessible resources.
The operational impact of this vulnerability extends beyond simple information gathering as it provides attackers with detailed knowledge of an organization's project structure, potentially revealing sensitive information about business operations, development cycles, and organizational hierarchy. An attacker could use this information to craft more targeted phishing campaigns, identify high-value targets within the organization, or plan more sophisticated attacks against specific projects. The exposure of project names and potentially associated metadata could reveal internal business processes, technology stacks, or even strategic initiatives that should remain confidential. This information disclosure could also facilitate further exploitation attempts by providing attackers with knowledge of project-specific configurations, user groups, or integration points that might be vulnerable to additional attacks.
Organizations should immediately upgrade to version 1.6.14_J8 or later to remediate this vulnerability, as the plugin vendor has addressed the authentication bypass issue through proper access control implementation. Additionally, security administrators should conduct thorough audits of all installed Jira plugins to identify similar vulnerabilities in other third-party extensions that may expose internal resources without proper authorization checks. Network segmentation and firewall rules can provide temporary mitigation by restricting access to the affected servlet endpoint, though this approach does not address the root cause. The vulnerability highlights the importance of implementing comprehensive security testing for third-party applications, particularly those that integrate with core business systems like Jira, and underscores the necessity of regular security assessments to identify and remediate access control weaknesses in enterprise software environments.
