CVE-2022-24181
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 · uneditedCross-site scripting (XSS) via Host Header injection in PKP Open Journals System 2.4.8 >= 3.3 allows remote attackers to inject arbitary code via the X-Forwarded-Host Header.
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 · moderate confidencePKP Open Journals System (OJS) versions 2.4.8 through 3.3.x are vulnerable to reflected cross-site scripting (XSS) via the X-Forwarded-Host HTTP header. Attackers can inject malicious scripts through the header that gets reflected in application responses without proper sanitization, potentially allowing session hijacking or defacement.

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 installed OJS versionAccess the admin dashboard and navigate to System Information or Administration > Site Settings to view the version number. Alternatively, check the version.php file in the OJS installation directory.Affected if version is 2.4.8 through 3.3.x (any version >= 2.4.8 and <= 3.3)
-
Check if X-Forwarded-Host header is processedSend a test HTTP request to the OJS application with an X-Forwarded-Host header containing a simple test value (e.g., X-Forwarded-Host: test.example.com) and examine the response to see if this value appears in any part of the rendered page.Affected if the X-Forwarded-Host value is reflected in the response without sanitization or encoding
-
Test for XSS via X-Forwarded-Host headerSend a crafted request with a malicious X-Forwarded-Host header value containing JavaScript (e.g., <script>alert(1)</script>) and verify whether this script executes or appears unescaped in the response body.Affected if the injected script payload is reflected verbatim in the HTML response without proper encoding or sanitization
-
Verify proxy configurationInspect the OJS configuration file (config.inc.php) for settings related to proxy headers, or check if the server is configured behind a reverse proxy that forwards the X-Forwarded-Host header to the application.Affected if proxy headers are being trusted and forwarded to the application without validation
You are affected if your OJS version is between 2.4.8 and 3.3.x and the X-Forwarded-Host header is reflected in application responses without sanitization.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataUpgrade to the latest patched version of OJS (3.4 or later) or apply vendor-supplied patches. Implement input validation on proxy headers like X-Forwarded-Host to reject malformed or malicious values.
