CVE-2009-2168 in 7ammel
Summary
by MITRE
cpanel/login.php in EgyPlus 7ammel (aka 7ml) 1.0.1 and earlier sends a redirect to the web browser but does not exit when the supplied credentials are incorrect, which allows remote attackers to bypass authentication by providing arbitrary username and password parameters.

The vulnerability identified as CVE-2009-2168 affects the EgyPlus 7ammel (also known as 7ml) web application version 1.0.1 and earlier. This authentication bypass flaw exists within the cpanel/login.php component of the software, representing a critical security weakness that undermines the application's ability to properly validate user credentials. The issue stems from improper handling of authentication failures within the login script, creating a scenario where the system fails to terminate execution upon incorrect credential submission.
The technical flaw manifests when the application processes authentication requests through the login.php endpoint. Upon receiving invalid credentials, the system performs a redirect operation to guide users back to the login page but fails to properly terminate the current script execution. This design flaw allows attackers to exploit the authentication mechanism by simply manipulating URL parameters with arbitrary username and password combinations. The application's failure to implement proper session management and execution flow control creates an opening for unauthorized access attempts.
This vulnerability directly relates to CWE-285, which addresses improper authorization within authentication mechanisms, and aligns with ATT&CK technique T1110.003 for credential access through brute force attacks. The operational impact is significant as it allows remote attackers to bypass the entire authentication system without requiring legitimate credentials. Attackers can leverage this weakness to gain unauthorized access to administrative panels, potentially leading to complete system compromise. The vulnerability affects the confidentiality, integrity, and availability of the web application by enabling unauthorized access to sensitive administrative functions.
The exploitation of this vulnerability follows a straightforward methodology where attackers can manipulate the login.php endpoint by appending arbitrary parameters to bypass authentication checks. This flaw essentially renders the authentication mechanism ineffective, as the system does not properly validate whether the user has legitimate access rights. The lack of proper exit conditions after failed authentication attempts creates a persistent vulnerability that can be exploited repeatedly without detection.
Mitigation strategies for CVE-2009-2168 should focus on implementing proper session management protocols and ensuring that authentication failures result in immediate script termination. System administrators should upgrade to patched versions of EgyPlus 7ammel, as the vulnerability has been addressed in subsequent releases. Additionally, implementing proper input validation and credential handling procedures within the login script can prevent similar issues. Network-level protections such as web application firewalls and access control lists can provide additional layers of defense. Regular security audits and penetration testing should be conducted to identify and remediate similar authentication bypass vulnerabilities in web applications. The fix typically involves modifying the login.php script to ensure proper execution flow control and implementing appropriate exit conditions upon authentication failures.
