CVE-2024-37383 represents a medium-severity cross-site scripting (XSS) vulnerability affecting Roundcube Webmail prior to version 1.5.7 and 1.6.x before 1.6.7. This vulnerability allows attackers to exploit SVG animate attributes, which can lead to unauthorized script execution. With a CVSS score of 6.1, the potential risks necessitate immediate attention from organizations utilizing the affected versions.
Risk to organizations includes unauthorized access and manipulation of sensitive user data, which can be exploited via network vectors. This vulnerability is particularly critical as it enables attackers to execute scripts that could compromise user accounts or manipulate webmail functionalities.
Given the exploitability status of this vulnerability, organizations should prioritize patching immediately to mitigate risks. The vulnerability was published on June 7, 2024, and is included in the Known Exploited Vulnerabilities (KEV) catalog, indicating that it poses a significant threat and should be addressed in the current patch cycle.
Roundcube has released patches in versions 1.5.7 and 1.6.7 to remediate the vulnerability. Organizations must ensure that their installations are updated to these versions to protect against potential exploitation.
Vulnerability Details
The official description for CVE-2024-37383 states that it allows XSS via SVG animate attributes in Roundcube Webmail before versions 1.5.7 and 1.6.x before 1.6.7. The vulnerability type is classified under CWE-79, which pertains to improper neutralization of input during web page generation. The CVSS score of 6.1 indicates a medium level of severity, highlighting the need for organizations to act swiftly.
The affected products include Roundcube Webmail and Debian Linux, specifically versions prior to the vendor patch. The vulnerability was disclosed on June 7, 2024, and organizations should consult their patch management strategies to identify and apply the necessary updates.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation of SVG animate attributes within the Roundcube Webmail application. The attack vector is network-based, requiring minimal complexity to exploit. Attackers do not need any privileges to exploit this vulnerability, but user interaction is necessary for successful execution, as the payload must be activated by a user viewing a malicious email or web content.
Regarding the impact of this vulnerability, it has low confidentiality and integrity impacts, as it primarily allows attackers to execute scripts within the context of the user’s session. However, there is no impact on availability, making this vulnerability particularly concerning for data confidentiality and integrity.
Risk & Impact Analysis
Organizations using Roundcube Webmail should be acutely aware of the risks associated with CVE-2024-37383. The potential for unauthorized script execution could lead to significant data breaches, compromising user data and organizational integrity. The blast radius for this vulnerability could extend across all users of the affected versions, heightening the urgency for organizations to address this issue promptly.
With a CVSS score of 6.1 and its inclusion in the KEV catalog, the urgency for remediation is high. Organizations should prioritize this in their patch management cycles and consider the potential impact on their operations and customer trust.
