CVE-2010-4751 in Chrome
Summary
by MITRE
SQL injection vulnerability in LightNEasy.php in LightNEasy 3.2.1, when magic_quotes_gpc is disabled, allows remote authenticated users to execute arbitrary SQL commands via the id parameter in an edituser action, a different vector than CVE-2008-6593, CVE-2010-3484, and CVE-2010-3485.

The vulnerability identified as CVE-2010-4751 represents a critical SQL injection flaw within the LightNEasy content management system version 3.2.1. This vulnerability specifically targets the LightNEasy.php script and exploits a fundamental weakness in input validation mechanisms when the PHP configuration parameter magic_quotes_gpc is disabled. The vulnerability operates through the id parameter within the edituser action, creating a pathway for malicious actors to manipulate database queries and execute unauthorized commands. Unlike previous vulnerabilities such as CVE-2008-6593, CVE-2010-3484, and CVE-2010-3485, this flaw presents a distinct attack vector that requires careful consideration of the specific operational context in which LightNEasy is deployed.
The technical implementation of this vulnerability stems from improper input sanitization within the application's database interaction layer. When magic_quotes_gpc is disabled, PHP does not automatically escape special characters in GET, POST, and COOKIE data, leaving the application directly vulnerable to SQL injection attacks. The id parameter in the edituser action becomes the primary attack surface where user-supplied input is directly concatenated into SQL query strings without adequate validation or escaping mechanisms. This flaw falls under the Common Weakness Enumeration category CWE-89, which specifically addresses SQL injection vulnerabilities where untrusted data is incorporated into SQL commands without proper sanitization. The vulnerability operates at the application layer and can be classified under the MITRE ATT&CK framework's T1190 technique for exploitation of remote services through SQL injection attacks.
The operational impact of this vulnerability extends beyond simple data theft or modification, as it provides authenticated attackers with the capability to execute arbitrary SQL commands on the underlying database server. This access level allows for complete database compromise, including but not limited to data exfiltration, privilege escalation, and potential lateral movement within the network infrastructure. Attackers can leverage this vulnerability to gain unauthorized access to user credentials, modify content, or even establish persistent backdoors within the application environment. The authenticated nature of the attack means that an attacker must first obtain valid user credentials, but once achieved, they can perform actions that would otherwise require administrative privileges within the LightNEasy application. The vulnerability creates a significant risk for organizations relying on this CMS, particularly those with limited security monitoring in place.
Mitigation strategies for CVE-2010-4751 should focus on immediate patching of the LightNEasy application to the latest available version that addresses this vulnerability. Organizations should also implement proper input validation and sanitization measures, ensuring that all user-supplied data is properly escaped or parameterized before being incorporated into database queries. The configuration of magic_quotes_gpc should be reviewed, with the recommendation to either enable this feature or implement robust alternative input validation mechanisms. Additionally, database access should be restricted through proper privilege management, ensuring that application accounts have minimal required permissions and that database connections are properly secured. Network segmentation and intrusion detection systems should be deployed to monitor for suspicious database activity patterns that may indicate exploitation attempts. Regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities within the application codebase.
