CVE-2007-3567 in MySQLDumper
Summary
by MITRE
MySQLDumper 1.21b through 1.23 REV227 uses a "Limit GET" statement in the .htaccess authentication mechanism, which allows remote attackers to bypass authentication requirements via HTTP POST requests.

The vulnerability identified as CVE-2007-3567 affects MySQLDumper versions 1.21b through 1.23 REV227 and represents a critical authentication bypass flaw that undermines the security of web applications relying on this tool. This issue stems from an improper implementation of access control mechanisms within the .htaccess file configuration, creating a significant security gap that adversaries can exploit to gain unauthorized access to sensitive database management interfaces.
The technical flaw manifests through the use of a "Limit GET" statement in the authentication mechanism, which specifically restricts access based on HTTP GET requests while failing to adequately secure POST requests. This implementation pattern creates a dangerous loophole where attackers can circumvent authentication controls by simply switching their request method from GET to POST, effectively bypassing the intended access restrictions. The vulnerability falls under the category of weak access control mechanisms, specifically aligning with CWE-285, which addresses improper authorization in authentication systems. The flaw demonstrates a fundamental misunderstanding of how HTTP methods should be handled within authentication frameworks, as it fails to implement comprehensive method-based access control.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it provides attackers with complete control over database management interfaces that typically contain sensitive information, administrative functions, and database configuration settings. Remote attackers can exploit this weakness to execute arbitrary commands, modify database contents, extract confidential data, or even establish persistent access to the underlying systems. This vulnerability directly aligns with ATT&CK technique T1190, which covers exploiting vulnerabilities in web applications, and represents a classic example of how insufficient input validation and access control implementation can lead to severe security breaches in web-based management tools.
Mitigation strategies for this vulnerability require immediate implementation of comprehensive access control measures that properly handle all HTTP request methods rather than relying on method-specific restrictions. Organizations should upgrade to patched versions of MySQLDumper or implement additional security controls such as IP whitelisting, enhanced authentication mechanisms, and proper input validation. The fix should involve comprehensive review and reimplementation of authentication logic to ensure that all HTTP methods are properly authenticated and authorized. Security professionals should also consider implementing web application firewalls and monitoring for suspicious POST request patterns that might indicate exploitation attempts. This vulnerability underscores the critical importance of proper access control design and demonstrates how seemingly minor implementation flaws can create significant security risks in web applications.
