Multiple vulnerabilities in the web-based management interface of Cisco Crosswork Network Controller could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against users of the interface of an affected system. These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by inserting malicious data into specific data fields 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. To exploit these vulnerabilities, the attacker must have valid administrative credentials. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
Vulnerability Details
The vulnerabilities have been classified under CWE-79, indicating a cross-site scripting issue. The CVSS score of 4.8 reflects a medium severity level. This score is significant as it indicates potential impacts on confidentiality and integrity, albeit with no impact on availability. Cisco Crosswork Network Controller versions 5.0.0 to 5.0.3, 6.0.0 to 6.0.2, and 7.0.0 to 7.0.0 are affected by these vulnerabilities. The publication date of the advisory was January 8, 2025.
Technical Analysis
The root cause of this vulnerability lies in improper input validation within the web-based management interface. The attack vector is through the network, allowing remote attackers to send crafted inputs to the interface. The attack complexity is classified as low, indicating ease of exploitation. The attacker requires high privileges, specifically administrative credentials, to exploit this vulnerability. User interaction is required for successful exploitation, as the attacker must entice a user to access the malicious input. The confidentiality impact is low, and the integrity impact is also low, with no availability impact.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive information and execution of arbitrary scripts in the context of the affected interface, which could lead to further exploitation or data breaches. The vulnerabilities present a medium risk level due to the requirement of valid administrative credentials, but organizations should prioritize patching immediately to mitigate these threats. The blast radius is moderate, affecting all instances of the specified versions of the Cisco Crosswork Network Controller.

Detection Guidance
Monitor logs for any unusual activity related to the web-based management interface. Key indicators include unexpected access attempts, unusual input patterns, and any attempts to execute scripts not originating from trusted sources. Implement network controls to restrict access to the management interface, ensuring only authorized personnel can reach it.
AppSecure Threat Intelligence Insight
This vulnerability highlights ongoing challenges in web application security, particularly concerning input validation mechanisms. Security teams should learn from this and enhance their defenses against XSS attacks. It is essential to adopt a proactive approach to web security, which includes regular audits and employing defensive coding practices. Organizations should also keep abreast of emerging threats and adjust their security posture accordingly. Exploring resources on penetration testing methodology can aid in understanding how to tighten security measures. Additionally, reviewing best practices in security testing is crucial for maintaining a robust security framework.
