CVE-2024-20334 in TelePresence Management Suite
Summary
by MITRE • 04/03/2024
A vulnerability in the web-based management interface of Cisco TelePresence Management Suite (TMS) could allow a low-privileged, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
This vulnerability is due to insufficient input validation by the web-based management interface. An attacker could exploit this vulnerability by inserting malicious data in a specific data field in the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

The vulnerability identified as CVE-2024-20334 represents a critical cross-site scripting flaw within Cisco TelePresence Management Suite TMS web interface, demonstrating a fundamental weakness in input validation mechanisms that exposes organizations to significant security risks. This vulnerability specifically affects the web-based management interface of Cisco's video conferencing management platform, which serves as the central control point for managing telepresence systems across enterprise environments. The flaw arises from inadequate sanitization of user inputs within specific data fields, creating an attack vector that can be exploited by low-privileged remote adversaries who may not possess legitimate administrative credentials.
The technical exploitation of this vulnerability follows a well-established XSS attack pattern where malicious data is injected into designated input fields within the TMS interface. When the vulnerable application processes this malformed input without proper validation or sanitization, it inadvertently executes the embedded malicious script within the context of the victim's browser session. This execution context allows attackers to perform actions such as stealing session cookies, modifying interface elements, redirecting users to malicious sites, or accessing sensitive information that the authenticated user can view. The vulnerability's classification aligns with CWE-79, which specifically addresses Cross-Site Scripting flaws in web applications, where insufficient validation of user-provided data creates opportunities for code injection attacks. The attack surface is particularly concerning given that TMS interfaces typically contain sensitive administrative controls and system configuration data that could be leveraged by attackers to escalate privileges or gain unauthorized access to video conferencing infrastructure.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable attackers to manipulate the telepresence management environment in ways that compromise both availability and confidentiality of the video conferencing services. Organizations relying on Cisco TMS for their video infrastructure may experience unauthorized access to meeting schedules, participant lists, system configurations, and potentially sensitive business communications that occur during video conferences. The low privilege requirement for exploitation means that even users with minimal access rights could potentially leverage this vulnerability to gain more extensive access to the system, creating a pathway for lateral movement within the network. This vulnerability also aligns with ATT&CK technique T1059.007 for Command and Scripting Interpreter: JavaScript, as it enables attackers to execute malicious JavaScript code within the victim's browser context, and T1566 for Phishing with Social Engineering, since the attack often requires user interaction through maliciously crafted interface elements.
Mitigation strategies for CVE-2024-20334 must address both immediate remediation and long-term security posture improvements. Organizations should prioritize applying Cisco's official security patches and updates as soon as they become available, as these typically include proper input validation and sanitization measures. Network segmentation should be implemented to limit access to the TMS interface to authorized administrative users only, reducing the attack surface available to potential attackers. Regular security audits of web application interfaces should include comprehensive input validation testing to identify similar vulnerabilities across other applications. The implementation of Content Security Policy headers and proper output encoding mechanisms can provide additional defense-in-depth measures that make successful exploitation more difficult even if similar vulnerabilities exist in other parts of the application. Security monitoring should include detection of unusual data input patterns in web interface fields, and access controls should be reviewed to ensure that only necessary users have access to the affected management interface. Additionally, regular security awareness training for administrators can help prevent social engineering attacks that might leverage this vulnerability by tricking users into interacting with maliciously crafted interface elements.
