Summary
by MITRE • 06/22/2026
IBM Datacap 9.1.7, 9.1.8, and 9.1.9 and IBM Datacap Navigator 9.1.7, 9.1.8, and 9.1.9 is vulnerable to cross-site scripting. This vulnerability allows an unauthenticated attacker to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.

IBM Datacap and IBM Datacap Navigator versions 9.1.7 through 9.1.9 contain a cross-site scripting vulnerability that represents a critical security weakness in the web-based user interface components. This vulnerability falls under CWE-79 which specifically addresses cross-site scripting flaws in software applications. The flaw exists within the web application's input validation mechanisms where user-supplied data is not properly sanitized before being rendered back to users, creating an opportunity for malicious code injection.
The technical implementation of this vulnerability allows an unauthenticated attacker to inject arbitrary javascript code through carefully crafted input fields or parameters within the web interface. When the vulnerable application processes and displays this malicious content without proper sanitization, it executes the injected javascript within the context of a victim's browser session. This particular weakness is classified as reflected cross-site scripting since the malicious payload is delivered via web requests and executed immediately upon page load.
The operational impact of this vulnerability extends beyond simple code injection, as it can potentially lead to complete session hijacking and credential disclosure within trusted browser sessions. Attackers can leverage this flaw to steal session cookies, capture user credentials, or perform actions on behalf of authenticated users. The attack vector does not require authentication, making it particularly dangerous as it can be exploited by anyone with access to the web application interface. This vulnerability directly aligns with ATT&CK technique T1531 which describes "Use of Web Shell" and T1071.004 which covers "Application Layer Protocol: DNS" in the context of credential theft through compromised web sessions.
Organizations utilizing these IBM Datacap versions face significant risk exposure given that the vulnerability affects core navigation and document processing functionalities. The attack surface includes all web-based interfaces and user interaction points within the application, making comprehensive patching essential for security posture maintenance. The vulnerability's severity is compounded by its potential to enable privilege escalation attacks where attackers can manipulate application behavior to access unauthorized data or functionality.
Mitigation strategies should include immediate implementation of security patches provided by IBM to address the specific javascript injection flaw in these versions. Organizations must also implement robust input validation controls at multiple layers including web application firewalls, content security policies, and proper encoding of user-supplied data before rendering. Network segmentation and monitoring solutions should be deployed to detect anomalous traffic patterns that may indicate exploitation attempts. Additionally, regular security assessments and code reviews should focus on identifying similar input validation weaknesses in other application components to prevent future vulnerabilities from emerging through the same architectural flaws that enabled this particular cross-site scripting attack vector.
The vulnerability demonstrates how seemingly minor input sanitization gaps can create significant security risks in enterprise document processing systems where sensitive business data is handled. Organizations should conduct thorough risk assessments of their deployed IBM Datacap environments and ensure all components are updated to versions that have resolved this specific javascript injection vulnerability. Continuous monitoring of application logs for potential exploitation attempts remains crucial since attackers may attempt to use this vulnerability as a stepping stone for more extensive system compromise.
