Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVE-2024-29890

High
8.8/10

Summary

DataLens is a business intelligence and data visualization system. A specifically crafted request allowed the creation of a special chart type with the ability to pass custom javascript code that would later be executed in an unprotected sandbox on subsequent requests to that chart. The problem was fixed in the datalens-ui version `0.1449.0`. Restricting access to the API for creating or modifying charts (`/charts/api/charts/v1/`) would mitigate the issue.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
