Apache JSPWiki Exposure Scanner

Apache JSPWiki is a feature-rich, open-source WikiWiki engine built on standard JEE components such as Java, servlets, and JSP. It is used by organizations and individuals to create and manage wiki-style collaborative content. Known for its modular design, it supports various plugins, templates, and configurations, making it a flexible choice for wiki-based knowledge management systems. JSPWiki is often deployed in corporate environments, educational institutions, and community-driven projects, enabling shared documentation and idea collaboration. Its integration with Java EE components ensures robust performance and compatibility with enterprise systems. The platform is designed to cater to both technical and non-technical users with its straightforward interface.

User IP Enumeration vulnerabilities arise when a web application exposes sensitive information, such as active user sessions or IP addresses, unintentionally. In Apache JSPWiki, this issue occurs through the SystemInfo page, which displays details about currently active wiki users and sessions. Such information can be leveraged by attackers for reconnaissance and targeted exploits. Detecting this exposure is crucial to prevent potential breaches and data leakage in the application environment. This vulnerability reflects improper configuration practices that lead to unnecessary data exposure to unauthorized users. Proactively addressing such exposures helps maintain the confidentiality and integrity of the application.

Technical details of this vulnerability involve accessing the `Wiki.jsp?page=SystemInfo` endpoint, which provides information about active wiki users and session data. The page includes indicators such as "Active Wiki Users" and "Number of active sessions." If exposed, it can be accessed without proper authorization, making the application vulnerable to information disclosure. Attackers can use these details to identify users or map internal systems, potentially leading to further exploitation. The vulnerability stems from insufficient access control mechanisms on sensitive endpoints in the JSPWiki application. Detecting and restricting unauthorized access to this endpoint is essential to safeguard user and system information.

When exploited, this vulnerability can lead to several adverse effects. Malicious actors may gain access to sensitive information about user sessions and their IP addresses, enabling targeted attacks or system reconnaissance. Such information can be used to launch phishing attacks, perform credential stuffing, or map internal network topologies. Unauthorized knowledge of active users may compromise the privacy of individuals or organizations using the wiki platform. It could also facilitate lateral movement within the network if attackers exploit other weaknesses based on enumerated information. Ultimately, this exposure may erode trust in the application and its developers.
