CVE-2011-10011
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 · uneditedWeBid 1.0.2 contains a remote code injection vulnerability in the converter.php script, where unsanitized input in the to parameter of a POST request is written directly into includes/currencies.php. This allows unauthenticated attackers to inject arbitrary PHP code, resulting in persistent remote code execution when the modified script is accessed or included by the application.
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 confidenceWeBid 1.0.2 has a remote code injection vulnerability in converter.php where the 'to' parameter from a POST request is written unsanitized directly into includes/currencies.php. Since the input is written directly to a PHP file without sanitization, attackers can inject arbitrary PHP code that executes when the file is subsequently included by the application.

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.
-
Locate the converter.php scriptSearch the web server document root for converter.php, typically found in the WeBid installation directoryAffected if converter.php exists and is accessible via the web server
-
Verify WeBid versionCheck the installed WeBid version by reviewing version files or the admin panelAffected if The installed version is WeBid 1.0.2 exactly
-
Inspect includes/currencies.php for injected codeOpen includes/currencies.php and search for any PHP code that was not part of the original installation, such as eval(), base64_decode(), shell_exec(), system(), or suspicious variable assignments containing executable codeAffected if The file contains unexpected PHP code segments, particularly ones with potentially malicious functions or encoded content
-
Check web server logs for exploitation attemptsReview web server access logs for POST requests to converter.php that include a 'to' parameter with unusual contentAffected if Recent POST requests to converter.php with a 'to' parameter are present in the logs
-
Compare includes/currencies.php to originalObtain a clean copy of includes/currencies.php from the official WeBid distribution and compare it byte-by-byte against the installed versionAffected if The installed file differs from the original, especially in areas handling currency conversion parameters
You are affected if WeBid 1.0.2 is installed, converter.php is web-accessible, and includes/currencies.php contains unauthorized injected PHP code or shows signs of modification.

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 sanitization on the 'to' parameter before writing to includes/currencies.php, and disable PHP execution in the includes directory to prevent injected code from running.
