Fortinet Discovers Symantec VIP Access DLL Preloading Vulnerability
Fortinet's FortiGuard Labs has discovered a DLL preloading vulnerability in Symantec Validation & Identification Protection (VIP) Access for Desktop.
Symantec VIP Access helps protect your online accounts and transactions by using a strong authentication process when you sign in to your VIP-enabled accounts. With Symantec VIP Access, both enterprise and end users can securely authenticate wherever and however they are accessing the services.
Symantec VIP Access for Desktop is susceptible to a DLL preloading vulnerability. The issue occurs when the application looks to load a DLL for execution and an attacker provides a malicious DLL to use instead. The application generally follows a specific search path to locate the DLL. The vulnerability can be exploited by a simple file write (or potentially an over-write) which results in a foreign DLL running under the context of the application.
Users should apply the solution provided by Symantec.
Fortinet reported the vulnerability to Symantec on June 6, 2017.
Symantec released patch for it on August 21, 2017.
This vulnerability was discovered by Kushal Arvind Shah of Fortinet's FortiGuard Labs.
