CVE-2019-17625
📋 TL;DR
CVE-2019-17625 is a stored cross-site scripting (XSS) vulnerability in Rambox 0.6.9 that allows attackers to inject malicious JavaScript into the application's service name field. When processed, this can lead to remote code execution via Node.js/Electron, potentially allowing full system compromise. All users of Rambox 0.6.9 are affected.
💻 Affected Systems
- Rambox Community Edition
📦 What is this software?
Rambox by Rambox
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining complete control over the victim's machine, allowing data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Local privilege escalation leading to unauthorized access to system resources, credential theft, and lateral movement within the network.
If Mitigated
Limited impact with proper input validation and output encoding preventing payload execution.
🎯 Exploit Status
Exploitation requires the attacker to have access to create or edit services in Rambox. The XSS payload can execute OS commands via Node.js/Electron's exec function.
