CVE-2024-47347 identifies a reflected Cross-site Scripting (XSS) vulnerability in the Ays Pro Chartify chart-builder software, affecting all versions up to and including 2.7.6. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker to inject malicious JavaScript code that is then reflected back to the user’s browser. This type of XSS is typically exploited by tricking a user into clicking a specially crafted URL or submitting malicious input that the application reflects without proper sanitization or encoding. When executed in the victim’s browser, the injected script can perform unauthorized actions such as stealing session cookies, redirecting users to malicious sites, or performing actions on behalf of the user within the context of the vulnerable application. The vulnerability does not require authentication, increasing its risk profile, but does require user interaction to trigger the malicious payload. Currently, there are no publicly known exploits or patches available, indicating that organizations using Chartify should prioritize mitigation efforts. The vulnerability affects the confidentiality and integrity of user data and can impact availability if leveraged in chained attacks. The lack of a CVSS score necessitates an expert severity assessment, which is high due to the potential impact and ease of exploitation. The vulnerability is relevant to any organization deploying Chartify, particularly those exposing the application to external or untrusted users.

The primary impact of CVE-2024-47347 is on the confidentiality and integrity of user data within affected Chartify deployments. Successful exploitation can lead to session hijacking, enabling attackers to impersonate legitimate users and access sensitive information or perform unauthorized actions. This can result in data breaches, unauthorized data manipulation, or disruption of business processes relying on Chartify visualizations. Additionally, attackers can use the vulnerability to deliver further malware or phishing attacks by redirecting users to malicious sites. Organizations with public-facing Chartify instances or those integrated into larger web platforms are at higher risk. The vulnerability could undermine user trust and lead to regulatory compliance issues if sensitive data is exposed. Although no known exploits are currently in the wild, the ease of exploitation and commonality of XSS attacks suggest a significant risk if left unmitigated.

To mitigate CVE-2024-47347, organizations should implement strict input validation and output encoding on all user-supplied data before rendering it in web pages. Specifically, ensure that any data reflected in the HTML context is properly escaped to prevent script execution. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. Deploy Web Application Firewalls (WAFs) with rules designed to detect and block reflected XSS payloads targeting Chartify endpoints. Monitor application logs for suspicious input patterns indicative of attempted XSS exploitation. Until an official patch is released by Ays Pro, consider restricting access to Chartify interfaces to trusted users or internal networks only. Educate users about the risks of clicking on untrusted links related to Chartify applications. Finally, maintain an incident response plan to quickly address any exploitation attempts.
