Summary
by MITRE • 09/10/2026
Italtel NFV 11.1.2-20210318 allows Multiple Stored XSS under NP_BCCAS-RMCTRL-01/IMCSCIWebGui/configuration.jsp?opration=list&object=announcementAS via the name, username, or mrfAnnouncementNameparameter. A malicious user leveraging this vulnerability could inject arbitrary JavaScript. The malicious payload will then be triggered every time an authenticated user browses the page containing it.

The identified vulnerability represents a classic Stored Cross-Site Scripting flaw within Italtel NFV version 11.1.2, specifically affecting the network element management interface accessible through the NP_BCCAS-RMCTRL-01/IMCSCIWebGui/configuration.jsp endpoint. This security issue is triggered when an authenticated user interacts with the announcement configuration module by supplying input via the name, username, or mrfAnnouncementName parameters during a list operation. The core technical flaw lies in the insufficient sanitization and validation of these specific input fields on the server side before they are persisted to storage. Unlike reflected XSS where malicious scripts are executed immediately from a crafted URL, stored vulnerabilities involve the injection of persistent code that is saved within the application's database or configuration files. Consequently, when any authenticated user subsequently accesses the affected page to view announcements, the browser retrieves and executes the injected JavaScript payload as part of the legitimate response content. This mechanism ensures that the malicious script runs in the context of the victim's session every time the compromised announcement list is rendered, creating a persistent threat vector rather than a one-time exploitation opportunity.
From an operational perspective, this vulnerability poses significant risks to the integrity and confidentiality of the network management system. An attacker who successfully exploits this flaw can execute arbitrary JavaScript code within the browser environment of any authenticated administrator or operator viewing the affected page. This capability allows for session hijacking through the theft of sensitive cookies or authentication tokens, potentially granting the attacker full control over the victim's account without needing to crack passwords. Furthermore, the malicious script can perform actions on behalf of the user, such as modifying configuration settings, deleting critical network elements, or redirecting users to phishing sites designed to capture further credentials. In a telecommunications infrastructure context managed by Italtel NFV, such unauthorized modifications could lead to service disruptions, misconfiguration of network parameters, or broader compromise of the underlying virtualized environment if the compromised session has elevated privileges. The persistent nature of stored XSS means that remediation is not limited to patching a single request but requires cleaning existing malicious entries from storage and ensuring all future inputs are strictly validated.
This vulnerability aligns with Common Weakness Enumeration identifier CWE-79, which classifies improper neutralization of input during web page generation as Cross-site Scripting. The attack vector leverages the application's trust in user-supplied data within a stored context, highlighting a failure to implement proper output encoding or input validation mechanisms for dynamic content insertion points. In terms of tactical classification under the MITRE ATT&CK framework, this exploitation falls under T1059, Command and Scripting Interpreter, specifically utilizing JavaScript execution via browser-based attacks. It also relates to T1213, Data from Information Repositories, as the attacker retrieves stored data (the malicious announcement) that contains executable code. The persistence of the payload distinguishes it from transient injection flaws, requiring a more comprehensive remediation strategy that addresses both immediate patching and historical data cleanup.
To mitigate this vulnerability, developers must implement strict input validation on all server-side parameters involved in storing user-generated content, particularly those related to announcement names or identifiers. This includes enforcing allowlists for acceptable characters, rejecting any HTML tags or JavaScript event handlers such as onload or onclick attributes, and applying context-sensitive output encoding when rendering data back into the web page. Additionally, implementing a Content Security Policy header can help mitigate the impact of successful XSS attacks by restricting the sources from which scripts are allowed to load and execute. For existing deployments, it is critical to audit database entries for any previously injected malicious payloads and remove them immediately after applying software updates or patches that address this specific flaw in the IMCSCIWebGui configuration module. Regular security assessments and code reviews focusing on input handling in web interfaces are essential to prevent similar stored injection vulnerabilities in future releases of network virtualization platforms.
