Vulnerability from variot

Cisco Secure Desktop (CSD) does not require that the ClearPageFileAtShutdown (aka CCE-Winv2.0-407) registry value equals 1, which might allow local users to read certain memory pages that were written during another user's SSL VPN session. Cisco Secure Desktop is prone to multiple information-disclosure vulnerabilities. Successfully exploiting these issues allows an attacker to gain access to potentially sensitive information; this may lead to other attacks. The following problems exist in the implementation of CSD, which may lead to the leakage of sensitive information related to SSL VPN sessions. Windows Page File Information Leakage Due to the way the Windows virtual memory subsystem operates, virtual physical memory used by any application, including in the Secure Desktop process space, may be written to the page file. The Windows page file stores the contents of the physical memory paged out without encryption, so data forensics tools can be used to recover the information paged out by the operating system. Due to this mechanism, CSD may not be able to delete all data generated and accessed in the SSL VPN session after the VPN session is terminated
