AI-suggested

1. Upgrade IPFire installations to version 2.29 (Core Update 198) or later, where the vulnerability is fixed. 2. Restrict access to the IPFire web interface to trusted administrators only, using network segmentation, VPNs, or IP whitelisting. 3. Enforce strong authentication mechanisms and monitor administrative access logs for suspicious activity. 4. Implement web application firewalls (WAF) or intrusion detection systems (IDS) to detect and block malicious payloads targeting the REMOTELOG_ADDR parameter. 5. Conduct regular security audits and penetration testing focused on the IPFire management interface. 6. Educate administrators about the risks of stored XSS and safe input handling practices. 7. If immediate upgrade is not possible, consider disabling remote syslog configuration via the web interface or sanitizing inputs at the proxy level as a temporary workaround.

Description

IPFire versions prior to 2.29 (Core Update 198) contain a stored cross-site scripting (XSS) vulnerability that allows an authenticated attacker to inject arbitrary JavaScript code through the REMOTELOG_ADDR parameter when updating the remote syslog server address. When a user updates the Remote logging Syslog server, the application issues an HTTP POST request to /cgi-bin/logs.cgi/config.dat and the server address is provided in the REMOTELOG_ADDR parameter. The value of this parameter is stored and later rendered in the web interface without proper sanitation or encoding, allowing injected scripts to execute in the context of other users who view the affected configuration page.
