A serious Cross-Site Request Forgery (CSRF) vulnerability has been discovered in Oddthinking EmailShroud, affecting versions up to and including 2.2.1. This vulnerability allows attackers to execute reflected XSS attacks, posing significant risks to organizations that utilize this plugin. The CVSS score of 7.1 categorizes this as a high-severity vulnerability, necessitating prompt action to address the issue.
The vulnerability was publicly disclosed on January 16, 2025, and organizations are urged to prioritize remediation to prevent possible exploitation. Given the nature of this vulnerability, the risk to organizations includes unauthorized actions taken on behalf of users, which could lead to data breaches or service disruptions.
Currently, there is no public exploit confirmed for this vulnerability, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, the potential for exploitation remains a concern, and organizations should remain vigilant.
Organizations should prioritize patching immediately. If patches are not available, mitigations should be implemented to reduce exposure until a fix is provided.
Vulnerability Details
The vulnerability allows for Cross-Site Request Forgery (CSRF) attacks, which can lead to reflected XSS. The CVSS score of 7.1 indicates a high severity, with the following metrics: attack vector is network-based, attack complexity is low, and no privileges are required for exploitation. The user interaction is required for an attack to be successful.
Affected versions include EmailShroud versions from n/a up to and including 2.2.1. The vulnerability is related to CWE-352, indicating it is a CSRF vulnerability.
Technical Analysis
The root cause of this vulnerability lies in the inadequate validation of user requests, allowing attackers to forge requests on behalf of users. The attack vector is over the network, and due to the low complexity of the attack, it can be executed easily by potential attackers. Given that no privileges are required and user interaction is necessary, the risk of exploitation increases as users engage with the compromised system.
The impacts of a successful attack include low confidentiality, integrity, and availability impacts, but they can still lead to serious consequences for the affected users and organizations.
Risk & Impact Analysis
The risk to organizations includes unauthorized actions taken on behalf of users, which could lead to data exposures or service disruptions. The potential blast radius is significant, especially for organizations using EmailShroud in sensitive or high-traffic environments. Given the CVSS score of 7.1, this vulnerability should be treated with high urgency, and organizations should address it in their priority patch cycle.
