CVE-2024-37384 is a medium-severity cross-site scripting (XSS) vulnerability affecting Roundcube Webmail versions prior to 1.5.7 and 1.6.x before 1.6.7. This vulnerability allows attackers to manipulate user preferences to execute arbitrary scripts in the context of the user's session. Given the nature of XSS attacks, the potential for data theft and unauthorized actions is significant. Organizations utilizing vulnerable versions of Roundcube Webmail should take this vulnerability seriously.
The CVSS score for this vulnerability is 6.1, indicating a medium severity level. The attack vector is network-based, requiring user interaction to trigger the exploit. Attack complexity is low, and no special privileges are required for an attacker to exploit this vulnerability. As such, organizations should prioritize addressing this issue within their patch management cycles.
Risk to organizations includes potential data breaches, loss of user trust, and possible regulatory repercussions if sensitive information is compromised. Given the increasing prevalence of XSS vulnerabilities in web applications, it is imperative for organizations to remain vigilant and proactive in their security measures.
Organizations should prioritize patching immediately. The vulnerability was published on June 7, 2024, and the corresponding patches are available in the release notes for versions 1.5.7 and 1.6.7.
Vulnerability Details
The official description of CVE-2024-37384 states that Roundcube Webmail before 1.5.7 and 1.6.x before 1.6.7 allows XSS via list columns from user preferences. This vulnerability falls under CWE-79, which pertains to improper neutralization of input during web page generation ('cross-site scripting'). The CVSS vector string for this vulnerability is 'CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N'.
The affected versions of Roundcube Webmail are as follows: versions prior to 1.5.7 and versions 1.6.x prior to 1.6.7. The vulnerability is particularly relevant for users of Debian Linux, specifically Debian 10.0.
Technical Analysis
The root cause of the vulnerability is the inadequate sanitization of user input in the list columns of user preferences, which leads to the execution of malicious scripts. The attack vector is network-based, meaning that an attacker can exploit the vulnerability remotely. Successful exploitation requires user interaction, as the victim must click on a malicious link that triggers the XSS attack. The attack complexity is low, as any user can be targeted without needing elevated privileges.
The confidentiality and integrity impacts are classified as low, meaning that while sensitive information may be accessible, the overall impact may vary based on the user's session. There is no availability impact, as the vulnerability does not disrupt service availability.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses significant risks. Attackers may leverage this vulnerability to perform data theft, manipulate user sessions, or launch further attacks against users. The blast radius is considerable, especially in environments where Roundcube Webmail is widely used for communication. Organizations must consider the potential fallout from such an attack, including loss of reputation, legal implications, and financial losses.
Given the CVSS score of 6.1 and the lack of any known active exploitation in the wild, organizations should address this vulnerability in their next patch cycle. However, they should remain vigilant for any changes in the threat landscape that may elevate the urgency of this situation.
