The vulnerability identified as CVE-2019-4746 affects IBM DOORS Next Generation (DNG/RRC) versions 6.0.2, 6.0.6, and 6.0.61, representing a critical cross-site scripting flaw that undermines the security integrity of the web-based user interface. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, which is classified as a common weakness in web application security. The flaw exists in the application's handling of user input within the web interface, where insufficient validation and sanitization of data allows malicious actors to inject malicious JavaScript code into the application's response. The vulnerability specifically impacts the web user interface components where user-provided data is rendered back to the browser without proper encoding or filtering mechanisms.
The operational impact of this vulnerability extends beyond simple functional disruption, as it creates a persistent threat vector that can be exploited to compromise user sessions and potentially access sensitive information. When a malicious user successfully injects JavaScript code through the vulnerable interface, the script executes within the context of the victim's browser session, which operates under the trust relationship of the legitimate application. This allows attackers to manipulate the application's behavior in ways that can capture user credentials, session tokens, or other sensitive data that flows through the trusted session. The vulnerability is particularly dangerous because it operates within the application's legitimate user interface, making it difficult to detect through standard network monitoring or intrusion detection systems.
The exploitation of this vulnerability aligns with tactics described in the MITRE ATT&CK framework under the technique T1059.007 for Command and Scripting Interpreter, specifically focusing on JavaScript execution within web browsers. Attackers can leverage this vulnerability to perform session hijacking, credential theft, or data exfiltration by crafting malicious input that gets processed and displayed within the web interface. The IBM X-Force ID 172885 associated with this vulnerability indicates the severity and recognition of the threat within the security community. Organizations using these vulnerable versions of DNG/RRC face significant risk of unauthorized access to their requirements management data and user authentication information, particularly in environments where users have elevated privileges or access to sensitive system information.
Organizations should immediately implement mitigations including applying the vendor-provided security patches and updates for the affected IBM DOORS Next Generation versions. Additionally, implementing proper input validation and output encoding mechanisms within the application's web interface can help prevent the injection of malicious scripts. Network-level protections such as web application firewalls and content security policies should be deployed to add additional layers of defense. Regular security assessments and user awareness training regarding the dangers of interacting with suspicious content or links within the application environment are also recommended. The vulnerability demonstrates the critical importance of maintaining current security patches and implementing defense-in-depth strategies to protect against persistent threats that exploit common web application weaknesses.
