CVE-2018-15703
Advantech WebAccess 8.3.2 and below is vulnerable to multiple reflected cross site scripting vulnerabilities.
Does this matter?
Lower severity and a low EPSS score (0.88%). Track it; it rarely justifies an emergency change on its own.
Description
Advantech WebAccess 8.3.2 and below is vulnerable to multiple reflected cross site scripting vulnerabilities. A remote unauthenticated attacker could potentially exploit this vulnerability by tricking a victim to supply malicious HTML or JavaScript code to WebAccess, which is then reflected back to the victim and executed by the web browser.
