CVE-2025-23672 is a high-severity vulnerability classified as Cross-site Scripting (XSS) in the tenteeglobal Instant Appointment plugin. This vulnerability allows for reflected XSS attacks, which can potentially lead to unauthorized actions on behalf of users and data exposure. The CVSS score for this vulnerability is 7.1, indicating a high level of risk that organizations should not overlook.
The vulnerability is particularly concerning since it allows attackers to exploit the application via a network. Given its nature, organizations utilizing the affected versions of the Instant Appointment plugin must prioritize remediation efforts to prevent potential exploitation. The urgency to patch this vulnerability is high due to the potential impact on user data and application integrity.
As of now, there are no known public exploits or proofs of concept (PoCs) available for this vulnerability, which may indicate a temporary window for organizations to mitigate risks before potential exploitation becomes widespread. Organizations should monitor this situation closely and implement the necessary patches to secure their systems.
Organizations should prioritize patching immediately to address this vulnerability and reduce their risk exposure.
Vulnerability Details
The vulnerability can be described as an improper neutralization of input during web page generation, specifically allowing for reflected XSS. The affected versions of the Instant Appointment plugin extend from n/a to version 1.2.
The CVSS score of 7.1 indicates a high severity, underscoring the need for immediate action. The attack vector is classified as NETWORK, with low attack complexity and no privileges required, meaning that a user interaction is necessary for exploitation. The confidentiality, integrity, and availability impacts are all rated as low.
Technical Analysis
The root cause of this vulnerability lies in the inadequate validation of user input during web page generation. Attackers may leverage this flaw to inject malicious scripts that execute within the context of the user's browser.
The attack vector is primarily network-based, and while the complexity is low, user interaction is required for activation. Therefore, a user must visit a crafted URL to trigger the XSS payload. The impacts on confidentiality, integrity, and availability are all rated as low, indicating that while the risks are manageable, they are still significant.
Risk & Impact Analysis
Risk to organizations includes potential data exposure and manipulation of user sessions, which can severely undermine user trust and application integrity. Given that the scope of the vulnerability is classified as changed, an exploit could affect not only the immediate user but also other users interacting with the application.
Organizations should assess the deployment of the Instant Appointment plugin and prioritize remediation due to the inherent risks associated with reflected XSS vulnerabilities. The urgency for addressing this vulnerability is high to prevent exploitation and subsequent damage.
