Name of the Vulnerable Software and Affected Versions Advantech WebAccess versions prior to V8.2 20170817

Description A Stack-based Buffer Overflow issue was discovered in the application, where it lacks proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. This could allow an attacker to execute arbitrary code under the context of the process.

Recommendations For versions prior to V8.2 20170817, update to version V8.2 20170817 or later to resolve the issue. As a temporary workaround, consider restricting access to the webvrpcs ViewDll1 to minimize the risk of exploitation.
