An unauthenticated path traversal vulnerability in Quix Page Builder Pro enables attackers to read sensitive files from the server, posing a high risk to data confidentiality.

The software fails to sanitize input within form elements, which allows an unauthenticated attacker to manipulate file paths. This results in the ability to traverse directories and access files that should otherwise be restricted.

The CVSS score of 8.7 highlights the high risk associated with this vulnerability, as it allows for the disclosure of sensitive configuration files, credentials, or source code. Such information exposure can facilitate further attacks against the server, leading to complete compromise of the application and underlying data.

Immediate Action: Update the Quix Page Builder Pro extension to the latest version released by ThemExpert. If an update is unavailable, disable the affected form functionality until a patch is applied.

Proactive Monitoring: Monitor server access logs for path traversal attempts, such as requests containing sequences like ../, which indicate malicious activity.

Compensating Controls: Utilize a Web Application Firewall (WAF) to detect and block requests containing directory traversal sequences directed at the Joomla installation.

Public Exploit Available: unknown

Path traversal vulnerabilities often serve as the first step in a larger attack chain, making this an urgent security concern. Organizations must prioritize applying the available vendor patches and ensure that security monitoring is active to detect any attempts to leverage this flaw.
