The CVE-2014-7267 vulnerability represents a cross-site scripting flaw within the Ricksoft WBS Gantt-Chart add-on version 7.8.1 and earlier for Atlassian JIRA platforms. This vulnerability specifically affects the output-page generator component responsible for rendering project management visualizations and reports. The flaw enables authenticated attackers to inject malicious web scripts or HTML content into the application's output pages, potentially compromising user sessions and data integrity. Unlike related vulnerabilities such as CVE-2014-7268, this particular issue manifests through distinct attack vectors that exploit the add-on's handling of user-generated content within its reporting mechanisms.
The technical implementation of this XSS vulnerability stems from inadequate input validation and output encoding within the Gantt chart add-on's page generation logic. When authenticated users access project reports or gantt chart views, the application fails to properly sanitize user-supplied data before incorporating it into dynamically generated HTML output. This insufficient sanitization creates opportunities for attackers to embed malicious JavaScript code, HTML tags, or other harmful content that executes in the context of other users' browsers. The vulnerability is particularly concerning because it operates within a legitimate JIRA add-on, making it more difficult to detect and potentially allowing attackers to remain undetected within the organization's trusted toolset.
The operational impact of CVE-2014-7267 extends beyond simple script injection, as it can enable attackers to perform various malicious activities within the compromised JIRA environment. Successful exploitation could allow threat actors to steal session cookies, redirect users to malicious websites, modify project data, or escalate privileges within the JIRA instance. The authenticated nature of the vulnerability means that attackers must first establish valid credentials, but once inside the system, they can leverage this flaw to expand their access and influence. Organizations using this add-on face potential data exposure, integrity compromise, and possible unauthorized modifications to critical project management information. The vulnerability particularly affects environments where JIRA is used for sensitive project tracking, as attackers could potentially access confidential project details or manipulate timelines and resource allocations.
Security professionals should implement multiple layers of defense against this vulnerability, beginning with immediate patching of the Ricksoft WBS Gantt-Chart add-on to version 7.8.2 or later where the flaw has been addressed. Organizations should also consider implementing Content Security Policy headers to limit script execution capabilities within JIRA environments and conduct regular security assessments of third-party add-ons. The vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications, and may be categorized under ATT&CK technique T1566 for initial access through malicious web content. Administrators should also review and restrict user permissions within JIRA to minimize the potential damage from successful exploitation, ensuring that only authorized personnel can access sensitive project data and modify critical configurations. Regular monitoring of JIRA logs for unusual activity patterns and implementing web application firewalls can further reduce the risk of exploitation.
