Organizr version 1.90 contains a cross site scripting vulnerability in the api.php component that allows remote attackers to inject malicious scripts into web pages viewed by other users. This vulnerability falls under CWE-79 which specifically addresses cross site scripting flaws where untrusted data is improperly incorporated into web page content without proper sanitization or encoding mechanisms. The flaw exists because the application fails to adequately validate and sanitize input parameters passed through the api.php endpoint, creating an opportunity for attackers to execute arbitrary JavaScript code in the context of victims' browsers.
The technical implementation of this vulnerability stems from insufficient output encoding and input validation practices within the api.php script. When user-supplied data is directly reflected in the application's response without proper sanitization, it creates a pathway for malicious payloads to be executed. Attackers can construct specially crafted requests containing script tags or other malicious code that gets processed and rendered by the vulnerable web application. This allows for session hijacking, credential theft, defacement of the application interface, and potential lateral movement within the network. The vulnerability is particularly dangerous because it affects the core api.php endpoint which likely handles various application functions and data processing operations.
The operational impact of this XSS vulnerability extends beyond simple script execution as it provides attackers with persistent access to user sessions and sensitive data. An attacker who successfully exploits this vulnerability can steal authentication cookies, modify application behavior, redirect users to malicious sites, or perform actions on behalf of authenticated users. The attack surface is broad since api.php endpoints typically handle critical application functions and may process user data from multiple sources. This vulnerability aligns with ATT&CK technique T1566 which covers social engineering through malicious content delivery, and T1071 which involves application layer protocol usage for command and control communications.
Organizations using Organizr v1.90 should immediately implement mitigations including input validation, output encoding, and proper parameter sanitization across all api.php endpoints. The recommended approach includes implementing Content Security Policy headers to restrict script execution, applying proper HTML entity encoding to all dynamic content, and validating all user inputs against whitelisted patterns. Additionally, the application should be updated to a patched version that addresses this vulnerability as soon as possible. Network segmentation and monitoring solutions should be employed to detect suspicious requests targeting the api.php endpoint, while regular security assessments should verify that similar vulnerabilities do not exist in other application components. The vulnerability demonstrates the critical importance of secure coding practices and input validation in preventing persistent security flaws that can compromise entire web applications and their user bases.
