Overview

Apache Zeppelin versions from 0.8.2 before 0.11.1 contain an Improper Encoding or Escaping of Output vulnerability (CVE-2024-31868). The vulnerability was discovered by H Ming and disclosed on April 9, 2024. The issue affects the helium module of Apache Zeppelin, allowing attackers to modify helium.json and expose XSS (Cross-site Scripting) attacks to normal users (OSS Security, NVD).

Technical details

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation - Cross-site Scripting). According to CISA's assessment, it has a CVSS v3.1 base score of 6.1 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, indicating network accessibility, low attack complexity, no privileges required, and user interaction required (NVD).

Impact

The vulnerability allows attackers to perform Cross-site Scripting (XSS) attacks against normal users through the modification of helium.json. This can lead to unauthorized access to user data and potential execution of malicious scripts in users' browsers (NVD).

Exploitability

The vulnerability requires network access and user interaction to exploit. No authentication is required to launch the attack, making it accessible to remote attackers. The attack complexity is considered low, indicating that the vulnerability is relatively straightforward to exploit (NVD).
