CVE-2010-0709 in Limny
Summary
by MITRE
Multiple cross-site request forgery (CSRF) vulnerabilities in Limny 2.0 allow remote attackers to (1) hijack the authentication of users or administrators for requests that change the email address or password via the user action to index.php, and (2) hijack the authentication of the administrator for requests that create a new user via the admin/modules/user/new action to limny/index.php.

The vulnerability described in CVE-2010-0709 represents a critical cross-site request forgery flaw affecting Limny 2.0 content management system. This weakness falls under the Common Weakness Enumeration category CWE-352, which specifically addresses cross-site request forgery vulnerabilities that enable attackers to perform unauthorized actions on behalf of authenticated users. The vulnerability exists due to the absence of proper anti-CSRF token validation mechanisms within the application's authentication and administrative workflows, creating a significant security risk for organizations relying on this software.
The technical implementation of this vulnerability manifests in two distinct attack vectors that exploit the lack of request validation. The first vector targets user authentication by allowing attackers to manipulate requests sent to index.php, enabling them to hijack user sessions and modify critical account information such as email addresses and passwords. The second vector specifically targets administrative functions, permitting attackers to create new user accounts through the admin/modules/user/new endpoint in limny/index.php. Both attack paths exploit the fundamental principle that authenticated requests are automatically processed without verifying the legitimacy of the request source, thereby bypassing the application's security controls.
The operational impact of this vulnerability extends beyond simple account compromise, as it provides attackers with elevated privileges within the application environment. When an authenticated user visits a malicious website or clicks on a crafted link, the CSRF attack can automatically submit requests that modify user accounts or create new administrative accounts, potentially leading to complete system compromise. This vulnerability particularly affects the principle of least privilege, as it allows attackers to perform administrative actions without proper authorization, potentially enabling them to establish persistent access or exfiltrate sensitive data. The attack requires minimal user interaction and can be executed through social engineering techniques, making it particularly dangerous in enterprise environments where users may inadvertently trigger these malicious requests.
Organizations affected by this vulnerability should implement immediate mitigations including the deployment of anti-CSRF tokens for all state-changing requests, particularly those involving authentication and administrative functions. The solution aligns with the ATT&CK framework's defense in depth principles, specifically addressing techniques related to credential access and privilege escalation. Proper implementation requires generating unique, unpredictable tokens for each user session and validating these tokens on every request that modifies user data or performs administrative actions. Additionally, organizations should consider implementing Content Security Policy headers to prevent unauthorized script execution and ensure that all user interactions with the application are properly authenticated and authorized. The vulnerability demonstrates the critical importance of input validation and request integrity checking as outlined in secure coding practices and industry security standards.
