The vulnerability identified as CVE-2015-0766 represents a critical cross-site scripting flaw within the administrative web interface of Cisco FireSIGHT System Software version 6.0.0. This security weakness exists within the Management Center component and affects the broader FireSIGHT system architecture that provides network security monitoring and threat prevention capabilities. The vulnerability manifests through unspecified input fields within the administrative interface, creating a pathway for malicious actors to execute arbitrary web scripts or HTML code within the context of authenticated user sessions. The affected system components operate within enterprise network security environments where privileged administrative access is required for system configuration and management, making this vulnerability particularly dangerous as it could enable attackers to gain unauthorized access to sensitive network security controls.
The technical exploitation of this vulnerability occurs through the injection of malicious scripts or HTML content into input fields that are not properly validated or sanitized before processing. This type of flaw falls under the CWE-79 category of Cross-Site Scripting, specifically representing a stored XSS vulnerability where malicious payloads are permanently stored on the server and executed when other users access the affected interface. The vulnerability affects multiple Bug IDs including CSCus93566, CSCut31557, and CSCut47196, indicating that the issue spans across different aspects of the Management Center component's input handling mechanisms. Attackers can leverage this weakness to execute code within the browser of authenticated administrators, potentially leading to session hijacking, privilege escalation, or complete system compromise. The vulnerability operates at the application layer and requires minimal privileges to exploit, as it targets the administrative interface that typically requires valid authentication credentials.
The operational impact of CVE-2015-0766 extends beyond simple script injection, as it fundamentally compromises the integrity and confidentiality of the network security infrastructure. An attacker who successfully exploits this vulnerability could potentially access sensitive system configuration data, modify security policies, or redirect users to malicious websites that could further compromise the network environment. The administrative web interface serves as the primary point of control for FireSIGHT system management, making this attack vector particularly devastating for enterprise security operations. The vulnerability could be leveraged to establish persistent access to the network security infrastructure, potentially enabling attackers to monitor network traffic, modify threat detection rules, or disable security features. This represents a significant threat to the CIA triad, particularly affecting confidentiality and integrity of the security monitoring system, while also potentially compromising availability through the ability to manipulate system configurations.
Organizations affected by this vulnerability should implement immediate mitigations including applying the vendor-provided security patches and updates released by Cisco to address the identified XSS flaws. Network segmentation and access control measures should be strengthened to limit access to the administrative interface to only authorized personnel with legitimate business needs. Input validation and output encoding mechanisms should be enhanced across all web applications, particularly those handling administrative functions. Security monitoring should be increased for suspicious activities within the administrative interface, including unusual input patterns or attempts to access restricted areas. The vulnerability aligns with ATT&CK technique T1059.007 for command and scripting interpreter, and T1566 for credential harvesting through social engineering, as attackers could use this vulnerability to establish persistent access and gather additional credentials. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other network security components, as this represents a common attack vector that affects many enterprise security systems. The remediation process should include comprehensive testing of the patched software to ensure that the XSS vulnerabilities are fully addressed without introducing regressions in system functionality.
