CVE-2009-0732
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 · uneditedDownloadcenter 2.1 stores common.h under the web root with insufficient access control, which allows remote attackers to obtain user credentials and other sensitive information via a direct request. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
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 confidenceDownloadcenter 2.1 stores the file 'common.h' under the web root without proper access controls. This file contains sensitive information such as user credentials. Remote attackers can directly request this file via HTTP to obtain the credentials.

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.
-
Confirm Lingx Downloadcenter 2.1 is installedCheck for the presence of Lingx Downloadcenter installation files or directories on the server. Look for typical web application directories like /downloadcenter, /lingx, or similar paths under the web root.Affected if Lingx Downloadcenter version 2.1 is installed on the server
-
Locate the common.h fileSearch for the file named 'common.h' within the web application's directory structure. Check common locations such as the root directory of the downloadcenter application, the /include or /lib subdirectories, or any directory under the web root where the application is installed.Affected if The file common.h exists within the web-accessible directory structure
-
Verify direct HTTP access to common.hAttempt to retrieve the file via HTTP by requesting the URL: http://[your-server]/[downloadcenter-path]/common.h or similar path. Use a web browser or curl command: curl http://target/common.hAffected if The common.h file is directly accessible via HTTP and returns the file contents
-
Confirm sensitive data is exposedExamine the contents of the retrieved common.h file. Look for patterns indicating credentials such as database connection strings, usernames, passwords, API keys, or other authentication-related strings.Affected if The accessible common.h file contains user credentials, database passwords, or other sensitive information in plain text
If Lingx Downloadcenter 2.1 is installed and the common.h file is accessible via direct HTTP request containing credentials, the environment is affected by this CVE.

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 dataMove common.h to a directory outside the web root, or configure the web server to deny direct access to .h files and other sensitive file types.
