Symantec VIP Access for Desktop prior to 2.2.4 can be susceptible to a DLL Pre-Loading vulnerability. These types of issues occur when an application looks to call a DLL for execution and an attacker provides a malicious DLL to use instead. Depending on how the application is configured, the application will generally follow a specific search path to locate the DLL. The exploitation of the vulnerability manifests as a simple file write (or potentially an over-write) which results in a foreign executable running under the context of the application.

Symantec VIP Enterprise Gateway (all versions) may be susceptible to a cross-site scripting (XSS) exploit, which is a type of issue that can enable attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to potentially bypass access controls such as the same-origin policy.

Symantec My VIP portal, previous version which has already been auto updated, was susceptible to a cross-site scripting (XSS) exploit, which is a type of issue that can enable attackers to inject client-side scripts into web pages viewed by other users or potentially bypass access controls such as the same-origin policy.

A code-execution vulnerability exists during startup in jhi.dll and otpiha.dll in Symantec VIP Access Desktop before 2.2.2, which could let local malicious users execute arbitrary code.
