The vulnerability identified as CVE-2010-4752 represents a critical SQL injection flaw within the LightNEasy content management system version 3.2.1. This vulnerability specifically affects installations where the PHP configuration parameter magic_quotes_gpc is disabled, creating a dangerous environment where user input is not automatically escaped before being processed by the database. The flaw resides in the LightNEasy.php script and manifests through the page parameter, which serves as the primary attack vector for malicious actors seeking to exploit this weakness.
The technical exploitation of this vulnerability occurs when an attacker crafts malicious input through the page parameter that gets directly incorporated into SQL queries without proper sanitization or parameterization. When magic_quotes_gpc is disabled, the PHP application fails to automatically escape special characters in GET, POST, and COOKIE data, allowing attackers to inject malicious SQL code that executes with the privileges of the database user. This creates a pathway for arbitrary code execution, data manipulation, and potential complete system compromise. The vulnerability is categorized under CWE-89, which specifically addresses SQL injection flaws where untrusted data is incorporated into SQL commands without proper validation or escaping mechanisms.
The operational impact of this vulnerability extends beyond simple data theft or modification, as it provides attackers with the capability to escalate privileges within the database environment and potentially gain deeper access to the underlying system. Attackers can leverage this vulnerability to extract sensitive information, modify database content, create new user accounts, or even execute system commands if the database user has sufficient privileges. The vulnerability's distinct nature from related CVEs such as CVE-2008-6593, CVE-2010-3484, and CVE-2010-3485 indicates it operates through a unique code path or input handling mechanism, making it particularly challenging to detect and mitigate through standard security measures.
From a threat modeling perspective, this vulnerability aligns with ATT&CK technique T1190, which involves exploiting vulnerabilities in web applications to gain unauthorized access to systems. The attack surface is particularly concerning given that many older web applications fail to properly implement input validation, especially when running on servers where security hardening measures like magic_quotes_gpc are disabled. Organizations running LightNEasy 3.2.1 should immediately implement proper input validation, parameterized queries, and output encoding to prevent exploitation. The recommended mitigations include upgrading to a patched version of LightNEasy, enabling magic_quotes_gpc if possible, implementing web application firewalls, and conducting thorough security audits of all database interactions. Additionally, the principle of least privilege should be enforced where database users have minimal necessary permissions to reduce the potential damage from successful exploitation.
