CVE-2014-3393 affects the Clientless SSL VPN portal customization framework in Cisco ASA Software 8.2 before 8.2(5.51), 8.3 before 8.3(2.42), 8.4 before 8.4(7.23), 8.6 before 8.6(1.14), 9.0 before 9.0(4.24), 9.1 before 9.1(5.12), and 9.2 before 9.2(2.4). The flaw is caused by improper implementation of authentication in the portal customization framework, allowing a remote unauthenticated attacker to modify Clientless SSL VPN portal customization objects stored in the RAMFS cache filesystem. In practice, this enables alteration of portal content such as the WebVPN login page, including insertion of malicious JavaScript/XSS payloads. Public reporting and incident-response observations show the vulnerability was exploited to inject credential-stealing scripts into Cisco ASA SSL VPN landing pages.
