This vulnerability allows improper neutralization of input during web page generation, specifically resulting in reflected Cross-site Scripting (XSS). This issue affects AcyMailing SMTP Newsletter versions prior to 9.11.1. With a CVSS score of 7.1, this vulnerability is classified as high severity, indicating significant risk to organizations that deploy affected systems.
Risk to organizations includes potential data theft, session hijacking, and the ability for attackers to execute arbitrary scripts in the context of the user’s browser. Given the nature of XSS vulnerabilities, the impact can be severe, especially if exploited in a sensitive environment. Organizations should prioritize patching immediately.
As of now, there are no known exploits for this vulnerability in the wild, but the potential for exploitation remains due to its classification and the nature of XSS. Organizations should actively monitor their systems for any signs of attempted exploitation.
Given the urgency, organizations are advised to implement the necessary updates or remediation steps in their patch management cycles.
Vulnerability Details
According to the official description, this vulnerability allows for reflected XSS in the AcyMailing SMTP Newsletter plugin, affecting versions from n/a to less than 9.11.1. The CVSS score of 7.1 indicates high severity; it is crucial for organizations to understand the implications of such vulnerabilities.
The CWE classification for this vulnerability is CWE-79, which pertains to improper neutralization of input during web page generation. The vulnerability was published on February 14, 2025.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation of input data, which allows attackers to inject malicious scripts into web pages. The attack vector is network-based, requiring user interaction to trigger the XSS payload. The attack complexity is low, meaning that even less skilled attackers could exploit this vulnerability given the right conditions.
No privileges are required for exploitation, meaning that any user can potentially be affected. The impact on confidentiality, integrity, and availability is categorized as low, but the potential for a high-impact breach remains, especially in user environments where sensitive information is handled.
Risk & Impact Analysis
The real-world risk of this vulnerability is notable, as XSS vulnerabilities can be exploited to perform actions on behalf of users, potentially leading to unauthorized access to user accounts and sensitive data. The blast radius is significant, especially for organizations that utilize the AcyMailing SMTP Newsletter plugin to communicate with clients or customers.
Organizations should assess their exposure to this vulnerability and implement necessary security measures. Given the CVSS score and the potential for exploitation, organizations need to address this vulnerability in their priority patch cycle.
According to EPSS, this vulnerability is not currently known to be actively exploited, but the nature of web vulnerabilities and the potential for exploit development means vigilance is required.
