Description
GFI MailEssentials AI versions prior to 22.4 contain a stored cross-site scripting vulnerability in the Sender Policy Framework Email Exceptions interface. An authenticated user can supply HTML/JavaScript in the ctl00$ContentPlaceHolder1$pv4$txtEmailDescription parameter to /MailEssentials/pages/MailSecurity/SenderPolicyFramework.aspx, which is stored and later rendered in the management interface, allowing script execution in the context of a logged-in user.
Analysis
Stored XSS in GFI MailEssentials AI versions before 22.4 allows authenticated users to inject malicious scripts into the Sender Policy Framework Email Exceptions interface that execute when administrators view the management console. An attacker with valid credentials can inject HTML/JavaScript through the email description parameter, compromising other logged-in users' sessions.
