This vulnerability allows stored XSS in the Truong Thanh ATP Call Now plugin, affecting versions up to and including 1.0.3. With a CVSS score of 5.9, this vulnerability is categorized as medium severity. The exploitation of this vulnerability can lead to unauthorized actions on behalf of users, making it a notable concern for organizations using this plugin.
The publication date of this vulnerability is June 20, 2025. Organizations utilizing the affected versions must take this vulnerability seriously as it could expose them to various risks, including data theft and unauthorized access. Given its classification as medium severity, the urgency for remediation should be addressed in the priority patch cycle.
Currently, there is no confirmed public exploit available for CVE-2025-50024, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations are encouraged to remain vigilant and monitor for any updates regarding potential exploits.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability.
Vulnerability Details
The CVE-2025-50024 vulnerability is rooted in improper handling of user inputs when generating web pages. The vulnerability affects the ATP Call Now plugin by allowing attackers to inject malicious scripts that can be stored and executed in the context of other users' browsers. The attack vector is network-based, requiring high privileges and user interaction, which increases the complexity of successful exploitation.
The attack complexity is considered low, making it easier for an attacker to exploit this vulnerability given the right conditions. The impacts on confidentiality, integrity, and availability are all rated as low, indicating that while the risks are present, they may not lead to severe consequences.
Technical Analysis
The root cause of CVE-2025-50024 stems from the lack of proper sanitization of user input during the web page generation process. This allows attackers to inject scripts that can be executed in the browser of another user who accesses the affected page.
The attack vector is network-based, which means that an attacker can exploit this vulnerability remotely, without requiring physical access to the vulnerable system. Given that high privileges are required for exploitation, it is likely that an attacker would need to trick a user into executing the malicious script, typically through social engineering or phishing.
User interaction is required to trigger the payload, which adds a layer of complexity to the attack. As such, organizations should ensure that their users are trained to recognize potential phishing attempts and suspicious links.
Risk & Impact Analysis
The risk to organizations includes potential unauthorized actions that could be performed on behalf of legitimate users, leading to data theft, account compromise, or further malware distribution. The blast radius for this vulnerability can extend beyond the immediate user, as the injected scripts can be used to target other users visiting the same web application.
Given the low confidentiality, integrity, and availability impacts, organizations should still assess their deployment to determine if the use of the affected plugin is critical. If so, they must implement immediate patching processes to mitigate risk and protect user data.

Affected Versions
The vulnerability affects the ATP Call Now plugin, specifically all versions prior to vendor patch 1.0.4. Organizations using versions up to and including 1.0.3 are recommended to update their installations to the latest version to mitigate this vulnerability.
Mitigation & Remediation
Organizations must apply the vendor patch to upgrade to version 1.0.4 or later. If immediate patching is not feasible, organizations should implement web application firewalls (WAF) to help filter out malicious input. Additionally, reviewing input validation mechanisms and ensuring proper sanitization of user inputs can mitigate the risks associated with this vulnerability.
For more comprehensive security strategies, organizations may consider engaging in penetration testing services to identify and address similar vulnerabilities.
Detection Guidance
To detect potential exploitation attempts, organizations should monitor logs for unusual activity related to user sessions. Indicators of compromise may include unexpected script execution, unusual user behavior, or failed login attempts that correlate with the timing of the vulnerability's exploitation.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2025-50024 underscores the importance of maintaining secure coding practices and regular patch management. Security teams must recognize the pattern of vulnerabilities that involve improper input validation and take proactive measures to address these weaknesses within their applications.
This incident serves as a reminder of the evolving threat landscape and the necessity for continuous security assessments. Organizations should leverage resources and frameworks available to bolster their security posture, including adopting best practices in penetration testing methodology and regular security training for developers.
To understand the broader implications of vulnerabilities like CVE-2025-50024, organizations should explore trends in vulnerability management programs that can aid in identifying and mitigating risks effectively.
