CVE-2024-23192 in OX App Suite
Summary
by MITRE • 04/08/2024
RSS feeds that contain malicious data- attributes could be abused to inject script code to a users browser session when reading compromised RSS feeds or successfully luring users to compromised accounts. Attackers could perform malicious API requests or extract information from the users account. Please deploy the provided updates and patch releases. Potentially malicious attributes now get removed from external RSS content. No publicly available exploits are known.

This vulnerability represents a critical cross-site scripting risk in RSS feed processing systems that could enable attackers to execute arbitrary code within user browser sessions. The flaw specifically manifests when RSS feeds contain malicious data-attributes that are not properly sanitized during content rendering. When users consume compromised RSS feeds or are redirected to malicious accounts, the embedded script code can execute in the context of their active browser session. This creates a significant attack surface where adversaries can leverage the trust relationship between users and RSS readers to bypass traditional security controls. The vulnerability operates at the intersection of web application security and content delivery systems, where legitimate content processing becomes a vector for malicious code execution.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization of RSS feed attributes, particularly those prefixed with data-. These attributes are commonly used for storing metadata and interactive elements within web applications but become dangerous when they contain executable JavaScript code. The flaw allows attackers to inject malicious scripts that can make API requests to the victim's account without their knowledge or consent. This capability enables a range of malicious activities including unauthorized data access, account takeovers, and potential lateral movement within compromised user environments. The vulnerability aligns with CWE-79 Cross-Site Scripting and CWE-20 Improper Input Validation, representing a classic example of how seemingly benign data attributes can become attack vectors.
The operational impact of this vulnerability extends beyond simple script injection to encompass potential account compromise and data exfiltration. When users read compromised RSS feeds, their browsers execute the injected malicious code, which can harvest session cookies, access stored credentials, or perform actions on behalf of the user. This creates a persistent threat vector that can remain active as long as the user continues to consume RSS content from compromised sources. The attack requires minimal user interaction beyond normal RSS consumption behavior, making it particularly dangerous in enterprise environments where users regularly consume external feeds. Security controls may not detect these attacks as they appear to be legitimate content delivery, creating a stealthy threat that can persist undetected for extended periods.
Organizations should implement immediate patching strategies to address this vulnerability by deploying the provided security updates that remove potentially malicious attributes from external RSS content. The remediation approach focuses on content sanitization at the point of ingestion, ensuring that data-attributes are properly validated and stripped of executable content before being rendered to users. Security teams should also implement additional monitoring for suspicious RSS feed activity and consider implementing content security policies that restrict script execution from external sources. The mitigation strategy should include regular security assessments of RSS feed consumption systems and implementation of web application firewalls that can detect and block malicious attribute patterns. This vulnerability demonstrates the importance of securing all content ingestion points and aligns with ATT&CK technique T1190 Exploit Public-Facing Application, highlighting the need for comprehensive security controls across all user-facing application components.
