Solution Type:
Vendor Patch

Summary:
The Clientless SSL VPN Portal of Cisco ASA is prone to a customization integrity vulnerability.

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
A vulnerability in the Clientless SSL VPN portal customization framework could allow an unauthenticated, remote attacker to modify the content of the Clientless SSL VPN portal, which could lead to several attacks including the stealing of credentials, cross-site scripting (XSS), and other types of web attacks on the client using the affected system. The vulnerability is due to a improper implementation of authentication checks in the Clientless SSL VPN portal customization framework.

Impact:
An unauthenticated, remote attacker could exploit this vulnerability by modifying some of the customization objects in the RAMFS cache file system. An exploit could allow the attacker to bypass Clientless SSL VPN authentication and modify the portal content. If successful, the attacker could conduct web-based attacks against a client using the affected software, which could be used to access sensitive information.

Affected Versions:
Version 8.2, 8.3, 8.4, 8.6, 9.0, 9.1 and 9.2

Recommendations:
Apply the appropriate updates from Cisco.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
