The vulnerability identified as CVE-2020-24007 affects Umanni RH 1.0, a web application that fails to implement proper authentication rate limiting mechanisms. This weakness creates a significant security risk by allowing unauthorized users to perform brute-force attacks against the login page without any restrictions on failed authentication attempts. The absence of account lockout policies or session throttling capabilities enables attackers to systematically test numerous username and password combinations until they successfully gain access to valid accounts. This flaw directly violates fundamental security principles that mandate protection against automated attack vectors and unauthorized access attempts.
From a technical perspective, the vulnerability represents a failure in access control implementation where the application lacks mechanisms to detect and prevent repetitive authentication failures. The system does not enforce any form of account lockout after a predetermined number of failed login attempts, nor does it implement temporary session blocking or IP address rate limiting. This absence of defensive controls creates an environment where attackers can exploit the application's authentication process without encountering any barriers to their brute-force efforts. The vulnerability can be classified under CWE-307, which specifically addresses inadequate protection against repeated authentication attempts, and aligns with ATT&CK technique T1110.003 for Brute Force Attacks against web applications.
The operational impact of this vulnerability is substantial as it provides attackers with a straightforward path to account compromise through automated means. An attacker can leverage tools such as hydra, medusa, or custom scripts to rapidly cycle through common username and password combinations, potentially gaining unauthorized access to user accounts, administrative privileges, or sensitive system resources. The lack of authentication attempt monitoring allows for prolonged attack windows where malicious actors can conduct extensive testing without detection or interruption. This vulnerability particularly affects applications that do not implement multi-factor authentication or additional security layers to protect against such attacks, making the impact more severe.
Effective mitigation strategies for this vulnerability involve implementing robust authentication rate limiting mechanisms that monitor and restrict failed login attempts from individual accounts or IP addresses. Organizations should deploy account lockout policies that temporarily disable accounts after a specified number of consecutive failed authentication attempts, typically ranging from three to five attempts depending on security requirements. Session management should incorporate temporary blocking mechanisms that prevent further authentication attempts from suspicious IP addresses or user accounts for predetermined time intervals. The implementation of CAPTCHA systems, two-factor authentication, and real-time monitoring of login patterns can further enhance security posture. Additionally, logging and alerting mechanisms should be configured to notify administrators of unusual authentication activity, enabling rapid response to potential attack attempts. These controls align with security frameworks such as NIST SP 800-63B and ISO 27001 requirements for access control and authentication management.
