The CVE-2016-10715 vulnerability represents a cross-site scripting flaw within the Artezio Kanban Board plugin version 1.4 revision 1914 for Atlassian Jira. This security weakness specifically manifests during the creation of new boards when the application fails to properly sanitize user input provided in the Board Name field. The vulnerability occurs within the artezioboard/mainPage.jspa?kanbanId=7#/kanban-view URI structure, which serves as the entry point for the malicious payload execution. The flaw allows attackers to inject malicious scripts that can execute within the context of other users' browsers, potentially compromising the integrity of the Jira environment and the data it manages. This type of vulnerability falls under CWE-79 which specifically addresses cross-site scripting vulnerabilities in web applications.
The technical exploitation of this vulnerability requires an attacker to create a new board within the Jira instance while providing malicious input in the Board Name field. When the board is created and subsequently viewed through the affected URI, the unsanitized input gets rendered back to the user's browser without proper HTML encoding or sanitization. This creates an environment where JavaScript code can be executed in the context of the authenticated user's session, potentially allowing for session hijacking, data theft, or further exploitation of the Jira instance. The vulnerability demonstrates poor input validation practices and highlights the critical importance of sanitizing all user-provided data before rendering it within web interfaces.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable attackers to perform various malicious activities within the Jira environment. An attacker could potentially steal session cookies, redirect users to malicious websites, or even modify board configurations to disrupt workflow processes. Since Jira is commonly used for project management and issue tracking in enterprise environments, this vulnerability could compromise sensitive business data and operational integrity. The vulnerability affects the core functionality of board creation and display, making it particularly dangerous as it can be exploited during routine administrative tasks. The issue represents a significant risk to organizations that rely on Jira for critical business operations and security-sensitive project management.
Organizations affected by this vulnerability should immediately apply the vendor-supplied patch or upgrade to a version of the Artezio Kanban Board plugin that addresses this XSS flaw. The mitigation strategy should include implementing proper input sanitization measures and ensuring that all user-provided data undergoes rigorous validation before being rendered in web interfaces. Security teams should also consider implementing web application firewalls and monitoring for suspicious activity related to board creation and viewing. This vulnerability aligns with ATT&CK technique T1211 which covers lateral movement through the exploitation of web application vulnerabilities, and organizations should consider implementing defense-in-depth strategies to prevent such attacks from succeeding. Regular security assessments and vulnerability scanning should be conducted to identify similar issues in other plugins or components within the Jira ecosystem.
