The vulnerability identified as CVE-2017-3810 represents a significant security flaw within Cisco Prime Service Catalog's web framework that enables authenticated remote attackers to execute URL redirect attacks against logged-in users. This vulnerability specifically affects version 10.0_R2_tanggula and potentially other releases within the affected product line. The issue stems from insufficient validation of redirect URLs within the web application's authentication flow, creating an avenue for malicious actors to manipulate user navigation and potentially execute social engineering attacks. The vulnerability operates under the Common Weakness Enumeration category CWE-601 which specifically addresses URL redirect vulnerabilities where applications redirect users to untrusted domains without proper validation.
Attackers exploiting this vulnerability can leverage the authenticated access to manipulate the web framework's redirect functionality, potentially redirecting users to malicious domains that appear legitimate within the context of the service catalog interface. The attack requires an authenticated session, meaning users must already have valid credentials to the system, but once authenticated, the attacker can manipulate the redirect behavior to compromise user sessions. This type of vulnerability falls under the ATT&CK technique T1534 which focuses on creating a false sense of security through deceptive redirects and navigation manipulation. The impact extends beyond simple redirection as it can facilitate credential theft, phishing attacks, or delivery of malicious payloads through the trusted user context.
The operational impact of this vulnerability is substantial as it undermines the trust model of the service catalog system and can lead to unauthorized access to sensitive business processes and data. Users who are logged into the system may be unknowingly redirected to attacker-controlled domains where they might enter credentials or download malicious software. The vulnerability particularly affects organizations that rely heavily on service catalog workflows where users perform critical business functions and maintain access to sensitive enterprise resources. Organizations with extensive use of Cisco Prime Service Catalog for IT service management, provisioning, and workflow automation face increased risk of successful exploitation.
Mitigation strategies for CVE-2017-3810 should focus on implementing strict URL validation mechanisms within the web framework to prevent unauthorized redirects. Organizations should ensure that all redirect URLs are validated against a whitelist of trusted domains and that any redirect attempts are properly sanitized to prevent injection attacks. The recommended approach includes updating to patched versions of Cisco Prime Service Catalog where available, implementing network-level controls to monitor and block suspicious redirect traffic, and establishing user awareness training to recognize potential redirect attacks. Security teams should also consider implementing web application firewalls that can detect and block malicious redirect patterns, while monitoring authentication logs for unusual redirect activities that might indicate exploitation attempts. Additionally, organizations should conduct regular security assessments of their web applications to identify similar vulnerabilities in other systems that might be susceptible to the same class of attack.
