CVE-2024-58342
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedXenForo before 2.2.17 and 2.3.1 allows open redirect via a specially crafted URL. The getDynamicRedirect() function does not adequately validate the redirect target, allowing attackers to redirect users to arbitrary external sites using crafted URLs containing newlines, user credentials, or host mismatches.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceXenForo before versions 2.2.17 and 2.3.1 contains an open redirect vulnerability in the getDynamicRedirect() function. The function fails to adequately validate redirect targets, allowing attackers to craft malicious URLs containing newlines, user credentials, or host mismatches to redirect users to arbitrary external sites.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed XenForo versionLog into the XenForo admin control panel and navigate to the Dashboard or About page to view the installed version number. Alternatively, check the version.php file in the src directory of your XenForo installation if you have file system access.Affected if The version displayed is lower than 2.2.17 or equals 2.3.0
-
Locate the getDynamicRedirect() function in the codebaseSearch the XenForo source files for the getDynamicRedirect function definition. This is typically found in controller-related files that handle redirection logic. Use grep or a file search tool to locate the function.Affected if The function exists and contains redirect handling logic without proper validation of newlines, credentials, or external host mismatches
-
Examine the redirect validation logicOpen the file containing getDynamicRedirect() and inspect the code that validates redirect targets. Look for whether the function checks for newline characters (\n, \r), validates that the redirect target matches the current host, or strips user credentials from the URL before performing the redirect.Affected if The code shows insufficient validation - missing checks for newlines, external hosts, or credential stripping in the redirect logic
-
Review web server logs for suspicious redirect patternsExamine your web server access logs for requests containing redirect parameters that include external URLs, newline characters (%0a, %0d), or @ symbols which could indicate credential-based redirects. Filter logs for common redirect parameter names used by XenForo.Affected if Log entries show requests with redirect URLs pointing to external domains or containing suspicious characters that should have been blocked by proper validation
Your environment is affected if XenForo version is lower than 2.2.17 or exactly 2.3.0, and the getDynamicRedirect() function lacks proper validation for external URLs, newlines, or credential-based redirects.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.2.17
Upgrade XenForo to version 2.2.17 or 2.3.1 or later to patch the insufficient redirect validation in getDynamicRedirect(). If immediate patching is not possible, implement web application firewall (WAF) rules to block requests with suspicious redirect patterns.
XenForo 2.2.17 (for 2.2.x) or XenForo 2.3.1 (for 2.3.x)
- 1. Back up your XenForo database and file system before proceeding
- 2. Identify your current XenForo version (2.2.x or 2.3.x branch)
- 3. Download XenForo 2.2.17 (if on 2.2.x branch) or XenForo 2.3.1 (if on 2.3.x branch) from the official xenforo.com customer area
- 4. Upload the new version files to your server, overwriting the existing installation
- 5. Navigate to the admin control panel and complete any pending database upgrades
- 6. Clear any caches (rebuild templates, etc.) if prompted
- 7. Verify the installation by checking the XenForo version and testing redirect functionality
