CVE-2025-68643
📋 TL;DR
Axigen Mail Server versions before 10.5.57 contain a stored cross-site scripting (XSS) vulnerability in the timeFormat account preference parameter. Attackers can inject malicious JavaScript that executes when victims access the WebMail interface, potentially compromising user sessions and data. This affects all organizations running vulnerable Axigen Mail Server instances.
💻 Affected Systems
- Axigen Mail Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, deploy ransomware, exfiltrate sensitive email data, or pivot to internal network systems.
Likely Case
Session hijacking, credential theft, phishing attacks from compromised accounts, and data exfiltration from user mailboxes.
If Mitigated
Limited to individual user account compromise if proper network segmentation and web application firewalls are in place.
🎯 Exploit Status
Requires two-stage attack: first stage to inject payload (needs credentials or another vulnerability), second stage when victim accesses WebMail. Stored XSS makes exploitation more reliable than reflected XSS.
