Detailsinfo

A vulnerability classified as problematic has been found in Cisco ASA up to 9.3(1) (Firewall Software). This affects an unknown function of the component SSL VPN. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on integrity.

The weakness was published 10/06/2014 by Alec Stuart-Muirk as CSCup54208 as confirmed security notice (Website). The advisory is shared at tools.cisco.com. This vulnerability is uniquely identified as CVE-2014-3399 since 05/07/2014. The exploitability is told to be easy. It is possible to initiate the attack remotely. The successful exploitation requires a authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1059 for this issue. The advisory points out:

The vulnerability is due to insufficient validation of the code that handles session information for the SSL VPN when a SharePoint handler is created. A SharePoint handler is created when a valid SharePoint connection is initiated. An attacker could exploit this vulnerability by sending crafted HTTP requests to the affected system. The SSL VPN feature must be configured for the system to be vulnerable.

The vulnerability scanner Nessus provides a plugin with the ID 79667 , which helps to determine the existence of the flaw in a target environment. It is . The commercial vulnerability scanner Qualys is able to test this issue with plugin 43422 (Cisco ASA SharePoint RAMFS Integrity and Lua Injection Vulnerability (CSCup54208)). The advisory illustrates:

An exploit could allow the attacker to overwrite arbitrary files on the RAMFS cache or inject Lua scripts, causing a denial of service (DoS) condition for the Clientless SSL VPN portal or causing the system to reload.

Upgrading eliminates this vulnerability. The upgrade is hosted for download at software.cisco.com. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (96818), Tenable (79667), SecurityFocus (BID 70251†), SecurityTracker (ID 1030972†) and Vulnerability Center (SBV-46368†).
