CVE-2025-34397

21
FAUCET Score

CVE-2025-34397 is a reflected cross-site scripting (XSS) vulnerability affecting MailEnable versions prior to 10.54, specifically in the /Mobile/Compose.aspx component. An attacker can exploit this by crafting a malicious URL that, when opened by a victim, injects arbitrary JavaScript due to improper sanitization of the 'Message' parameter. This medium-severity vulnerability (CVSS 6.1) allows for actions like redirecting victims, stealing non-HttpOnly cookies, or performing actions as the authenticated user, requiring user interaction (UI:R) for successful exploitation. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
