The vulnerability identified as CVE-2020-7995 affects Dolibarr version 10.0.6 and specifically targets the authentication mechanism within the htdocs/index.php?mainmenu=home login page. This issue represents a significant security weakness that undermines the system's ability to prevent brute force and credential stuffing attacks. The flaw allows attackers to perform an unlimited number of failed authentication attempts without any rate limiting or account lockout mechanisms, creating an exploitable condition that can be leveraged for various malicious activities.
This vulnerability stems from the absence of proper rate limiting controls within the authentication flow of the Dolibarr web application. The system fails to implement any form of adaptive authentication throttling or account lockout procedures that would normally be expected in secure authentication systems. The lack of such protections creates an environment where automated attack tools can systematically test countless username and password combinations without encountering any barriers. This design flaw directly violates security best practices outlined in the OWASP Top Ten and aligns with CWE-307, which addresses improper restriction of repeated activities.
The operational impact of this vulnerability extends beyond simple credential guessing attacks and can enable more sophisticated assault vectors including account enumeration, where attackers can determine valid user accounts through pattern analysis of system responses. The unlimited authentication attempts capability allows for potential denial of service conditions against legitimate users while simultaneously providing attackers with ample opportunity to discover valid credentials through automated means. This vulnerability particularly affects organizations that rely on Dolibarr for business management and customer relationship management, as the compromise of authentication systems can lead to unauthorized access to sensitive business data, financial records, and customer information.
Organizations utilizing Dolibarr 10.0.6 should implement immediate mitigations including the application of the vendor-provided security patches and the implementation of additional defensive measures. Network-level rate limiting should be deployed at firewalls and reverse proxies to restrict the number of authentication attempts from individual IP addresses. The system should also be configured with account lockout mechanisms that trigger after a predetermined number of failed attempts. Security monitoring should be enhanced to detect unusual authentication patterns and potential brute force activity. From an ATT&CK framework perspective, this vulnerability maps to T1110 which covers Brute Force and T1078 which addresses Valid Accounts, making it a critical target for defensive security operations.
The remediation approach should involve upgrading to a patched version of Dolibarr where the authentication rate limiting has been properly implemented. Organizations should also consider implementing multi-factor authentication as an additional security layer and establish comprehensive logging of authentication events to enable better threat detection and incident response capabilities. The vulnerability highlights the importance of proper authentication design and the necessity of adhering to security standards such as NIST SP 800-63B for authentication system security requirements. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other applications within the organization's attack surface.
