CVE-2010-2851
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 · uneditedSQL injection vulnerability in the BookLibrary From Same Author (com_booklibrary) module 1.5 and possibly earlier for Joomla! allows remote attackers to execute arbitrary SQL commands via the id parameter in a view action to index.php.
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 confidenceSQL injection vulnerability in the Joomla! BookLibrary component (com_booklibrary) allows remote attackers to execute arbitrary SQL commands via the id parameter in a view action to index.php. The vulnerable component fails to properly sanitize user input before using it in SQL queries.

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 if Joomla BookLibrary component is installedCheck for the presence of the com_booklibrary directory in the Joomla installation, typically found at /components/com_booklibrary/ or by reviewing the Joomla extension manager for the BookLibrary componentAffected if The com_booklibrary component directory exists in the Joomla components folder or is listed in the extension manager
-
Determine the installed BookLibrary versionCheck the manifest file or version file within the component directory, commonly at /components/com_booklibrary/booklibrary.xml or inspect the component's admin interface for version informationAffected if The installed version matches 1.5 (exact match to the affected version)
-
Verify the vulnerable parameter is accessibleAttempt to access a URL pattern such as index.php?option=com_booklibrary&view=yourview&id=1 to confirm the component responds to the id parameter in a view actionAffected if The component processes requests with the id parameter without immediate error
-
Check if SQL error messages are exposedSubmit a malformed id value (such as id=1' OR '1'='1) and observe whether the response contains SQL error messages or unexpected database-like outputAffected if SQL errors or database information is revealed in the response, indicating unsanitized input is processed
If the BookLibrary component version 1.5 is installed and the id parameter in view actions processes user input without sanitization (evidenced by SQL error disclosure), the environment is affected by CVE-2010-2851.

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 dataUpdate the BookLibrary component to a patched version that properly sanitizes the id parameter using prepared statements or parameterized queries. If no update is available, disable or remove the vulnerable component.
