The CVE-2012-2960 vulnerability represents a critical cross-site scripting flaw within the import functionality of HP ArcSight Connector and Logger appliances. This vulnerability affects specific versions including ArcSight Connector appliance 6.2.0.6244.0 and ArcSight Logger appliance 5.2.0.6288.0, making them susceptible to remote code execution through malicious web scripts. The flaw exists in the way these security appliances handle file imports, specifically when processing crafted input files that contain malicious JavaScript or HTML content. Attackers can exploit this vulnerability by uploading or importing specially crafted files that contain embedded scripts, which then execute in the context of other users who view or interact with the imported data. This vulnerability directly maps to CWE-79 - Improper Neutralization of Input During Web Page Generation, which is a fundamental weakness in web application security where user-supplied data is not properly sanitized before being rendered in web pages.
The operational impact of this vulnerability extends beyond simple script injection, as it enables attackers to perform session hijacking, deface web interfaces, steal sensitive data, or redirect users to malicious websites. When an attacker successfully exploits this vulnerability, they can manipulate the behavior of legitimate users who interact with the imported data, potentially gaining unauthorized access to sensitive security information or compromising the integrity of the security monitoring infrastructure. The ArcSight appliances are designed for security monitoring and log management, making them prime targets for attackers seeking to compromise security operations centers or gain unauthorized access to security event data. This vulnerability particularly affects organizations that rely heavily on ArcSight for security information and event management, as it undermines the trust model of these critical security tools.
The exploitation of CVE-2012-2960 aligns with several ATT&CK techniques including T1059.007 - Command and Scripting Interpreter: JavaScript and T1566.001 - Phishing: Spearphishing Attachment. Attackers typically leverage this vulnerability through malicious file attachments or crafted import files that appear legitimate but contain embedded malicious scripts. The vulnerability's impact is particularly severe in enterprise environments where ArcSight appliances serve as central security monitoring systems, as successful exploitation could allow attackers to manipulate security event logs, hide malicious activities, or compromise the entire security monitoring infrastructure. Organizations using these appliances should consider the vulnerability's potential for lateral movement within networks, as attackers could use the compromised appliances as a foothold to access other systems within the security operations environment. The remediation approach requires immediate patching of affected versions, implementation of strict input validation for all import operations, and enhanced monitoring of import activities to detect potential exploitation attempts.
