Description
A stack-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer, which could allow an attacker to execute arbitrary code under the context of the process.
