CVE-2019-15823 Scanner

WPS Hide Login is a popular WordPress plugin used to secure the login page of websites by changing the default login URL to a custom one. It is widely used by WordPress administrators to enhance the security of their websites and prevent unauthorized access. Many website owners rely on this plugin to manage access to their site's backend by obfuscating the standard WordPress login page. The tool provides an added layer of protection against automated login attempts. By modifying the default login path, WPS Hide Login reduces the risk of brute force attacks on a WordPress site. With its easy setup and effectiveness, it is a crucial tool for maintaining WordPress site security.

The vulnerability detected in WPS Hide Login involves a configuration file disclosure, which allows attackers to bypass login protection. This weakness exists due to an insufficient security check mechanism in the plugin versions prior to 1.5.3. By exploiting this vulnerability, attackers can send specially crafted requests to gain access to restricted areas of a WordPress site. This exposure potentially compromises the security model intended by the use of the plugin. The issue primarily affects the way login security parameters are handled and can lead to unauthorized access if not patched.

Technically, the vulnerability lies in the plugin's oversight during requests handling, particularly when processing the 'action=confirmaction' parameter. This oversight allows attackers to craft requests that bypass security measures designed to protect the login page. The vulnerable endpoint '/wp-login.php' accepts crafted URL parameters which manipulate the plugin's intended security checks. Furthermore, the security bypass occurs due to a failure in the plugin's logic to correctly validate access parameters. The flaw may permit unauthorized users to reach login pages otherwise protected by WPS Hide Login.

If exploited, this vulnerability can result in severe security risks such as unauthorized access to the admin panel of affected WordPress sites. Once access is gained, malicious actors could potentially alter site content, access sensitive information, or further compromise other network resources. The disclosure of this vulnerability poses a threat to the confidentiality, integrity, and availability of the affected websites. Therefore, site administrators need to address this issue promptly to prevent exploitation.
