The CVE-2018-1220 vulnerability affects EMC RSA Archer versions prior to 6.2.0.8 and represents a critical web application security flaw within the QuickLinks feature. This vulnerability falls under the CWE-601 Open Redirect weakness category, which occurs when an application redirects users to external URLs without proper validation of the destination. The flaw specifically enables attackers to manipulate the redirect functionality to point users toward malicious websites that can be crafted to appear legitimate. The vulnerability exists because the application fails to properly validate and sanitize URL parameters used in the QuickLinks implementation, allowing unauthorized redirection to attacker-controlled domains.
The technical exploitation of this vulnerability requires a remote attacker to craft malicious links that leverage the QuickLinks feature to redirect users from legitimate Archer application pages to phishing sites. When users click on these manipulated links, they are automatically redirected to the attacker's controlled domain without any warning or validation by the application. The attack vector is particularly dangerous because it can be executed through social engineering tactics where users are tricked into clicking seemingly legitimate links that appear to originate from the trusted Archer application. The vulnerability demonstrates a fundamental lack of input validation and output encoding in the web application's redirect mechanism.
The operational impact of this vulnerability is severe as it directly enables credential theft and information disclosure attacks. Users who are redirected to phishing websites can be tricked into entering their login credentials, personal information, or sensitive data that may be required for Archer application access. This creates a significant risk for organizations that rely on RSA Archer for business continuity management, risk assessment, and compliance tracking, as attackers could potentially gain unauthorized access to critical business data. The vulnerability also undermines user trust in the application and could lead to regulatory compliance issues, particularly in industries with strict data protection requirements such as financial services or healthcare organizations.
Organizations should immediately implement multiple layers of mitigation strategies to address this vulnerability. The primary recommendation involves applying the official EMC security patches released for RSA Archer version 6.2.0.8 and subsequent releases. Additionally, network-level controls such as web application firewalls should be configured to monitor and block suspicious redirect patterns. Implementing strict URL validation and sanitization mechanisms within the application code can prevent unauthorized redirection attempts. Security awareness training for users should emphasize the importance of verifying URLs before clicking on links and reporting suspicious redirects. The vulnerability also aligns with ATT&CK technique T1566 which describes the use of phishing techniques to gain initial access, making it essential for organizations to implement comprehensive email filtering and user education programs. Organizations should also consider implementing network segmentation to limit the potential impact of successful exploitation and establish monitoring procedures to detect unusual redirect activities within their Archer environments.
