CVE-2024-25608 Scanner

Liferay Portal is a comprehensive platform used for creating digital experiences across the web, mobile, and connected devices. Organizations worldwide leverage it as an open-source enterprise portal for building web applications and services. Its robust features make it popular in sectors such as education, government, and healthcare. Liferay allows for personalization, integration of diverse systems, and accessing a wide range of applications. The platform is favored for its flexibility and ability to facilitate collaboration and increased efficiency. With a large community and support network, Liferay provides the tools needed to adapt and grow in an ever-changing digital environment.

The open redirect vulnerability in Liferay Portal arises when the HtmlUtil.escapeRedirect function can be circumvented. An attacker can exploit this by using the "REPLACEMENT CHARACTER" (U+FFFD) in URLs, redirecting users to unintended external destinations. This flaw affects multiple parameters within the portal, including 'redirect', 'FORWARD_URL', and 'noSuchEntryRedirect'. Given its nature, it's crucial because it might lead users to malicious websites unwittingly. The potential phishing attacks or delivery of malware highlight the dangers of such a vulnerability. Proper security measures and regular software updates are vital for maintaining the integrity of web applications.

The vulnerability hinges on several parameters within Liferay Portal that are susceptible to exploitation. By appending the "REPLACEMENT CHARACTER" (U+FFFD) to a URL parameter, attackers can direct browser traffic to unintended sites. Key vulnerable parameters include 'redirect', 'FORWARD_URL', and 'noSuchEntryRedirect'. Specifically, this technique manipulates URL parsing to trick the application into producing a 302 redirect to a malicious endpoint. This level of detailed attack vector reveals how a single character modification can compromise user trust and system security. As a critical issue in such widely-used software, understanding these technical specifics aids in remediation and prevention strategies.

Exploiting the open redirect vulnerability could lead users unknowingly to malicious websites, facilitating phishing campaigns and malware distribution. A successful redirect might collect user credentials or deliver harmful payloads directly to users' systems. For businesses and institutions, this could result in data breaches or significant reputational damage. The economic implications are considerable, with potential losses tied to user data theft or system remediation costs. Furthermore, persistence of this vulnerability might erode stakeholder trust and impact user experience significantly. Consistent updates and security checks are necessary to mitigate these risks effectively.
