CVE-2024-6485: Medium Vulnerability in Bootstrap

A security vulnerability has been discovered in bootstrap that could enable Cross-Site Scripting (XSS) attacks. This vulnerability allows attackers to inject malicious JavaScript code into the data-loading-text attribute within the button plugin. When the button's loading state is triggered, this malicious code may be executed, potentially compromising user data and application integrity.

The CVSS score for this vulnerability is 6.4, classifying it as medium severity. Organizations utilizing affected versions of Bootstrap should take this vulnerability seriously, as it presents a viable attack vector that can be exploited with relative ease.

Risk to organizations includes unauthorized access to sensitive information and potential damage to reputation. Given the nature of XSS vulnerabilities, the impact can be significant, particularly if exploited in a production environment.

With confirmed exploit availability, it is critical for organizations to assess their usage of Bootstrap and implement necessary mitigation strategies. Organizations should prioritize patching immediately.

Vulnerability Details

This vulnerability allows Cross-Site Scripting (XSS) attacks associated with the data-loading-text attribute within the button plugin of Bootstrap. The CVSS score is 6.4, indicating medium severity due to its potential impact on confidentiality, integrity, and availability. The specific CWE classification for this vulnerability is CWE-79.

The vulnerability was published on July 11, 2024, and is currently awaiting further analysis. Organizations using versions of Bootstrap that include this vulnerability should assess their applications promptly.

Technical Analysis

The root cause of this vulnerability stems from improper handling of user input within the data-loading-text attribute. The attack vector is network-based, requiring a high level of complexity to exploit due to the need for user interaction, such as clicking the button. No privileges are required to execute this attack, making it accessible to any user.

The confidentiality impact is classified as high, as attackers may access sensitive information through script execution. The integrity and availability impacts are considered low, reflecting the nature of the exploitation.

Risk & Impact Analysis

Real-world deployment risk associated with this vulnerability is significant. Organizations that fail to address this issue may find themselves exposed to XSS attacks, leading to unauthorized access to sensitive data and potentially severe impacts on their reputation and customer trust.

The urgency for addressing this vulnerability is high, given its exploitability and the confirmed existence of a proof of concept. Organizations should address in priority patch cycles.

Affected Versions

Specific affected versions are not listed. Users should consider all versions prior to the availability of a patch as potentially vulnerable.

Mitigation & Remediation

To remediate this vulnerability, organizations should apply any available patches for Bootstrap. If a patch is not yet available, consider implementing workarounds such as sanitizing user input for the data-loading-text attribute. Additionally, configuration hardening practices should be reviewed to minimize attack surfaces.

Organizations should validate remediation through penetration testing to ensure the effectiveness of the applied fixes.

Detection Guidance

Monitoring for unusual behaviors in applications utilizing the Bootstrap library is essential. Look for log indicators such as execution of unexpected scripts or unauthorized changes to the data-loading-text attributes.

Behavioral anomalies, such as unexpected user interactions that trigger loading states, should also be logged and investigated.
