This cross site scripting vulnerability exists in the Joget workflow management platform within the User Profile Menu component. The flaw is specifically located in the submitForm function of the wflow-core/src/main/java/org/joget/plugin/enterprise/UserProfileMenu.java file. The vulnerability manifests when user-supplied input data is not properly sanitized or validated before being rendered back to the user interface. Attackers can exploit this weakness by manipulating the firstName and lastName parameters, which are then processed through the vulnerable function and subsequently displayed without adequate output encoding or sanitization measures.
The technical implementation of this vulnerability stems from insufficient input validation and output encoding practices within the web application's user profile handling mechanism. When the system processes user submissions containing malicious script payloads in the firstName or lastName fields, these inputs are directly incorporated into the HTML response without proper HTML entity encoding or script tag filtering. This allows an attacker to inject malicious JavaScript code that executes in the context of other users' browsers who view the affected profile information, creating a classic cross site scripting scenario that falls under CWE-79 - Improper Neutralization of Input During Web Page Generation.
The operational impact of this vulnerability is significant as it enables remote code execution capabilities within the context of user sessions. An attacker who successfully exploits this vulnerability can potentially steal session cookies, perform actions on behalf of authenticated users, or redirect victims to malicious websites. The attack vector is entirely remote, meaning that exploitation does not require any local access to the system. This makes the vulnerability particularly dangerous in multi-user environments where different users may view profile information, as the malicious payload could affect any user who accesses the compromised profile data. The vulnerability aligns with ATT&CK technique T1566.001 - Phishing: Spearphishing Attachment, as attackers could craft malicious profile entries to deliver payloads through social engineering campaigns.
The vulnerability is addressed through the release of version 7.0.34, which includes the patch identified by commit hash 9a77f508a2bf8cf661d588f37a4cc29ecaea4fc8. This patch likely implements proper input sanitization and output encoding mechanisms for user profile data, ensuring that any potentially malicious content is neutralized before being rendered in web pages. Organizations should immediately upgrade their Joget installations to version 7.0.34 or later to mitigate this risk. Additional mitigations include implementing proper content security policies, conducting regular security assessments of user input handling mechanisms, and establishing input validation rules that prevent the injection of script tags or other malicious content into profile fields. The vulnerability demonstrates the importance of secure coding practices, particularly in web applications where user data is frequently processed and displayed, and underscores the necessity of regular security updates and patch management programs.
