CVE-2017-12704

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

Description A heap-based buffer overflow issue was discovered due to a lack of proper validation of the length of user-supplied data prior to copying it to the heap-based buffer. This could allow an attacker to execute arbitrary code under the context of the process.

Recommendations For Advantech WebAccess versions prior to V8.2 20170817, update to version V8.2 20170817 or later to resolve the issue. As a temporary workaround, consider restricting the input of user-supplied data to prevent exploitation until a patch is applied.
