CVE-2006-5036
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 · uneditedMySource Matrix 3.8 and earlier, and MySource 2.x, allow remote attackers to use the application as an HTTP proxy server via the sq_remote_page_url parameter to access arbitrary sites with the server's IP address and conduct cross-site scripting (XSS) attacks. NOTE: the researcher reports that "The vendor does not consider this a vulnerability.
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 confidenceMySource Matrix 3.8 and earlier and MySource 2.x contain an open HTTP proxy vulnerability via the sq_remote_page_url parameter. Remote attackers can abuse this to route requests through the vulnerable server, enabling anonymized access to arbitrary sites and facilitating XSS attacks by leveraging the server's trusted IP address.

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 MySource versionLog into the MySource admin interface and navigate to the System Preferences or About section to view the version number. Alternatively, check version files in the web root directory if accessible.Affected if The version number is 2.16.2 or lower for MySource Classic, or 3.8 or lower for MySource Matrix.
-
Locate the sq_remote_page_url parameter entry pointIdentify a page within the MySource application that accepts the sq_remote_page_url GET or POST parameter. This is typically found in frontend page requests or proxy-related functionality.Affected if The parameter is accepted and processed by the application without proper validation.
-
Test whether the proxy functionality is activeSend a test HTTP request to the application with sq_remote_page_url set to an external domain you control or a known external site. Observe if the application returns content from that external URL.Affected if The application returns content from the URL specified in sq_remote_page_url, indicating the open proxy is functional.
-
Verify the proxy allows arbitrary destinationsRepeat the test with different target domains or IP addresses to confirm the proxy does not restrict destinations to an allow-list.Affected if The application proxies requests to arbitrary external sites without restriction.
The system is affected if it runs MySource Classic 2.16.2 or earlier or MySource Matrix 3.8 or earlier AND the sq_remote_page_url parameter is accessible and functions as an open proxy to arbitrary external sites.

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 dataImplement strict input validation and URL allow-listing for the sq_remote_page_url parameter, or disable the functionality entirely. Consider deploying a WAF to filter suspicious proxy requests and restrict outbound connections at the network level.
