CVE-2012-2494 – Cisco AnyConnect VPN Client Verification Bypass Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2012-2494

The VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 2.x before 2.5 MR6 and 3.x before 3.0 MR8 does not compare the timestamp of offered software to the timestamp of installed software, which allows remote attackers to force a version downgrade by using (1) ActiveX or (2) Java components to offer signed code that corresponds to an older software release, aka Bug ID CSCtw48681. La implementación de descargas en VPN en la funcionalidad WebLaunch de Cisco AnyConnect Secure Mobility Client v2.x antes v2.5 MR6 y v3.x antes de v3.0 MR8 no compara la fecha y hora del software que se ofrece con la marca de tiempo del software instalado, lo que permite forzar a una reducción de versión a atacantes remotos mediante el uso de componentes (1) ActiveX o (2) Java para ofrecer código firmado que corresponde a una versión anterior de software. Se trata de un problema también conocido como Bug ID CSCtw48681. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Cisco AnyConnect VPN Client. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists because the VPN AnyConnect helper program does not check the version number of the vpndownloader.exe program it downloads. • http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120620-ac • CWE-20: Improper Input Validation •
