CVE-2018-0129 in Data Center Analytics Framework
Summary
by MITRE
A vulnerability in the web-based management interface of Cisco Data Center Analytics Framework could allow an unauthenticated, remote attacker to conduct a reflected cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information. Cisco Bug IDs: CSCvh02088.

The vulnerability identified as CVE-2018-0129 resides within the web-based management interface of Cisco Data Center Analytics Framework, representing a critical security flaw that enables unauthenticated remote attackers to execute reflected cross-site scripting attacks. This vulnerability stems from inadequate input validation mechanisms within the web interface, specifically failing to properly sanitize user-supplied data before processing and rendering it back to users. The flaw allows malicious actors to inject malicious scripts that can execute in the context of authenticated users' browsers, potentially compromising the integrity and confidentiality of sensitive information.
The technical exploitation of this vulnerability follows a classic reflected XSS attack pattern where an attacker crafts a malicious URL containing scripted code and deceives a victim into clicking the link. When the victim's browser requests the malicious URL, the web application reflects the injected script back to the user's browser, executing it in the context of the current session. This attack vector is particularly dangerous because it requires no authentication from the attacker and can leverage the victim's existing privileges within the web interface. The vulnerability specifically affects the web-based management interface of affected Cisco Data Center Analytics Framework devices, making it accessible to attackers who can reach the device's management interface.
The operational impact of this vulnerability extends beyond simple script execution, as it can potentially enable attackers to access sensitive browser-based information, manipulate data within the interface, or even escalate privileges if the interface provides administrative functions. The reflected nature of the attack means that the malicious code is not stored on the server but is instead reflected back to the user's browser, making it difficult to detect through traditional security monitoring. This vulnerability directly aligns with CWE-79 which defines cross-site scripting as a weakness where web applications fail to properly validate or encode user input, and it maps to ATT&CK technique T1059.001 for command and scripting interpreter. The attack can result in session hijacking, data theft, and unauthorized access to the management interface.
Mitigation strategies for this vulnerability should prioritize immediate patching of affected Cisco Data Center Analytics Framework devices through official Cisco security advisories and firmware updates. Network segmentation and access controls should be implemented to limit exposure of management interfaces to trusted networks only, while also employing web application firewalls to detect and block malicious requests. Regular security assessments and input validation testing should be conducted to identify similar vulnerabilities in other web applications. Organizations should also implement user awareness training to recognize suspicious links and phishing attempts that could exploit this vulnerability. Additionally, monitoring for unusual traffic patterns and implementing strict input sanitization measures at the application layer can help prevent exploitation attempts. The vulnerability demonstrates the importance of robust input validation and output encoding in web applications, particularly those handling sensitive management functions, and serves as a reminder of the critical need for comprehensive security testing throughout the software development lifecycle.
