Browser script execution via stored contact fields
Published Oct 4, 2023 · Updated Sep 5, 2024
Stored XSS in EFS Software Easy Address Book Web Server 1.6 allows remote attackers to execute JavaScript when a victim loads users_admin.ghp. The handler stores unneutralized values from contact fields such as firstname, homephone, lastname, and workaddress and renders them when the page loads. Exploitation requires a victim to load the administrative page; the resulting code runs in that browser context and can alter displayed application data.
