CVE-2022-30983 Cross-Site Scripting in NoPaperForms Niaa-Chatbot

CVE-2022-30983 — Cross-Site Scripting in NoPaperForms Niaa-Chatbot Vulnerability Overview Vulnerability Type: Cross-Site Scripting (XSS) Vulnerability Description: A cross-site scripting (XSS) vulnerability was discovered in the support chat component of NoPaperForms Niaa-Chatbot. The vulnerability occurs when controlled input provided by an attacker via the chatbot's email input is not adequately sanitized before being rendered in the application. Successful exploitation could allow arbitrary JavaScript or HTML to be executed in the context of the affected website. CVE ID: CVE-2022-30983 CWE ID: CWE-79 — Improper Neutralization of Input During Web Page Generation Vendor: NoPaperForms Solutions Pvt. Ltd. Product: Niaa-Chatbot Affected Component: Support chat email input Attack Vector: Remote Researcher: Raj Zamal Date of Discovery: Before May 17, 2022 Date of CVE Assignment: May 18, 2022 Impact Affected Versions: The vulnerability was observed in Niaa-Chatbot deployments released prior to May 17, 2022. Affected Component: Niaa-Chatbot -> Support Chat -> Email Input Security Impact: Successful exploitation allows attacker-controlled JavaScript to be executed in the security context of the website hosting the vulnerable chatbot. Depending on the application configuration and the privileges available in the victim's browser session, exploitation may allow an attacker to: - Read information exposed on the affected page. - Modify content displayed to the victim. - Perform actions within the application using the victim's session. - Access browser storage available to the victim's browser. - Interact with application APIs accessible to the victim's browser. - Redirect users to attacker-controlled content. - Perform phishing or user interface manipulation within a trusted website. Remediation Recommended Fixes: - Treat all user-controlled values as untrusted when processing chatbot input. - Apply context-aware output encoding before rendering user-controlled data. - Do not construct HTML using untrusted input via APIs such as . - Use safe DOM APIs such as when inserting plain text. - Implement strict server-side validation for email addresses. - Sanitize HTML only when necessary. - Implement restrictive Content Security Policies (CSP) as an additional defense-in-depth control. - Ensure that validation and sanitization are implemented on the server side, rather than relying solely on client-side controls. - Review other chatbot input fields for similar injection vulnerabilities.
