Executive Summary
CVE-2024-3687 is a recently identified vulnerability in the bihell Dice 3.1.0 application, specifically within its Comment Handler component. This vulnerability, classified as Cross-Site Scripting (XSS), allows remote attackers to inject malicious scripts into web pages viewed by other users. Although the CVSS v3.1 Base Score is relatively low at 3.5, the public disclosure of the exploit details significantly increases the risk of exploitation. This report provides a detailed analysis of the vulnerability, its potential exploitation, and recommended mitigation strategies.
Technical Information
CVE-2024-3687 is a Cross-Site Scripting (XSS) vulnerability identified in the bihell Dice 3.1.0 application. The vulnerability is located in the Comment Handler component, which fails to properly neutralize user input during web page generation. This improper neutralization allows attackers to inject malicious scripts that can be executed by other users who view the affected web pages.
The vulnerability has been assigned a CVSS v3.1 Base Score of 3.5, indicating a low severity. The CVSS vector is AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N, which translates to the following: the attack vector is network-based, the attack complexity is low, the attacker requires low privileges, user interaction is required, the scope is unchanged, there is no impact on confidentiality, a low impact on integrity, and no impact on availability.
The CVSS v2.0 Base Score is 4.0, with a vector of AV:N/AC:L/Au:S/C:N/I:P/A:N. This indicates that the attack is network-based, has low complexity, requires single authentication, has no impact on confidentiality, partial impact on integrity, and no impact on availability.
The vulnerability is categorized under CWE-79, which refers to Improper Neutralization of Input During Web Page Generation. This type of vulnerability is commonly exploited to execute arbitrary scripts in the context of the user's browser, potentially leading to session hijacking, defacement, or redirection to malicious sites.
Exploitation in the Wild
As of the latest reports, there have been no confirmed instances of CVE-2024-3687 being exploited in the wild. However, the exploit details have been publicly disclosed, which increases the likelihood of future exploitation. Malicious actors can access the exploit information and potentially use it to target vulnerable systems.
Indicators of Compromise (IOCs) for this vulnerability would include unusual script execution in the context of the bihell Dice 3.1.0 application, unexpected changes in web page content, and reports from users about suspicious activities while interacting with the Comment Handler component.
APT Groups using this vulnerability
Currently, there are no specific Advanced Persistent Threat (APT) groups known to be exploiting CVE-2024-3687. However, XSS vulnerabilities are often targeted by a wide range of threat actors, including cybercriminals and state-sponsored groups, due to their potential to facilitate initial access or privilege escalation within a network. Organizations in sectors such as finance, healthcare, and government should be particularly vigilant, as these sectors are frequently targeted by APT groups.
Affected Product Versions
The primary product affected by CVE-2024-3687 is bihell Dice 3.1.0. Users of this version are advised to take immediate action to mitigate the risk associated with this vulnerability. It is also recommended to check for any updates or patches provided by the vendor that address this specific issue.
Workaround and Mitigation
To mitigate the risk posed by CVE-2024-3687, the following steps are recommended:
Input Validation: Implement robust input validation mechanisms to ensure that all user inputs are properly sanitized before being processed by the application. This can prevent the injection of malicious scripts.
Output Encoding: Use output encoding techniques to ensure that any data rendered in the browser is properly encoded, preventing the execution of injected scripts.
Security Patches: Regularly check for and apply any security patches or updates provided by the vendor. These patches may address the vulnerability and prevent exploitation.
Web Application Firewall (WAF): Deploy a Web Application Firewall to detect and block malicious requests targeting the Comment Handler component. A WAF can provide an additional layer of security by filtering out potentially harmful traffic.
User Education: Educate users about the risks associated with XSS vulnerabilities and encourage them to report any suspicious activities or unexpected behaviors while using the application.
