Attack-Flow Graph

Executive Summary

CVE-2026-79035 is a reflected cross-site scripting (XSS) vulnerability in Zeta Marketing Platform (ZMP) v1.0. It exists in the 'ca' parameter of the p.rfihub.com component, which is used for programmatic advertising. The server returns user input in the 'ca' parameter without proper validation or encoding, allowing attackers to inject malicious JavaScript via a crafted URL.

Detection Guidance

To detect this reflected XSS vulnerability, monitor network traffic for requests to p.rfihub.com with the 'ca' parameter containing suspicious payloads. Use tools like Burp Suite or OWASP ZAP to intercept and inspect GET requests for the 'ca' parameter. Check server responses for reflected input without proper encoding.

Impact Analysis

This vulnerability can lead to session hijacking by stealing cookies or session tokens, phishing attacks where users are tricked into submitting sensitive data, defacement of web pages, or malware delivery by redirecting users to malicious downloads. Attackers exploit it by convincing victims to click a specially crafted link.

Compliance Impact

This vulnerability could lead to data breaches, unauthorized access to user data, or exposure of sensitive information, which may violate GDPR and HIPAA compliance requirements. Organizations using ZMP v1.0 may face legal and regulatory penalties due to insufficient protection against XSS attacks.

Mitigation Strategies

Implement input validation to restrict the 'ca' parameter to expected values. Apply HTML/JS sanitizers to user input and use context-aware HTML encoding before displaying it. Deploy a Content Security Policy (CSP) to block untrusted script execution.
