CVE-2019-25397: IPFire 2.21 Core Update 127 Cross-Site Scripting via hosts.cgi

IPFire 2.21 Core Update 127 contains multiple reflected cross-site scripting vulnerabilities in the hosts.cgi script that allow attackers to inject malicious scripts through unvalidated parameters. Attackers can submit POST requests with script payloads in the KEY1, IP, HOST, or DOM parameters to execute arbitrary JavaScript in users' browsers.

Security readout for executives and security teams

Plain-English summary

CVE-2019-25397 affects IPFire 2.21 Core Update 127. The web management interface component hosts.cgi can reflect attacker-supplied script into a user’s browser. This usually requires a user to be tricked into submitting or visiting malicious content. Business risk is moderate, mainly browser-session abuse or unauthorized actions through an administrator’s session.

Executive priority

Treat as a targeted administrative-interface risk, not an internet-wide emergency based on available evidence. Prioritize if IPFire administration is broadly reachable or used by privileged staff. Validate versions and restrict management access while confirming vendor remediation.

Technical view

The issue is reflected cross-site scripting in IPFire hosts.cgi due to unvalidated parameters including KEY1, IP, HOST, and DOM. CVSS is 6.1, with network attack vector, low complexity, no privileges, and required user interaction. Scope is changed, with low confidentiality and integrity impact and no availability impact.

Likely exposure

Exposure is limited to IPFire 2.21 Core Update 127 systems, especially where the web administration interface is reachable by administrators or less-trusted networks. Systems not running that specific version are not identified as affected in the provided sources.

Exploitation context

A public ExploitDB entry exists, but the source bundle does not show CISA KEV listing or confirmed active exploitation. Successful exploitation requires user interaction and would execute JavaScript in the victim’s browser context, commonly relevant to administrative web sessions.

Researcher notes

Evidence supports reflected XSS in hosts.cgi for IPFire 2.21 Core Update 127. The bundle includes a public exploit reference, but no KEV status and no confirmed in-the-wild exploitation. The provided download reference appears to be the affected release, not necessarily a fix.

Mitigation direction

  • Identify any IPFire 2.21 Core Update 127 deployments.
  • Restrict IPFire web administration access to trusted management networks.
  • Review IPFire vendor guidance for fixed versions or official remediation.
  • Upgrade away from the affected Core Update if vendor guidance confirms a fixed release.
  • Warn administrators against opening untrusted links while authenticated to IPFire.

Validation and detection

  • Confirm installed IPFire version and Core Update level.
  • Inventory where the IPFire web administration interface is reachable.
  • Review logs for suspicious requests to hosts.cgi around administrator sessions.
  • Check whether compensating access controls limit web UI exposure.
  • Track vendor or advisory updates for remediation confirmation.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
