CVE-2025-23699 is a high-severity vulnerability classified as improper neutralization of input during web page generation, specifically allowing reflected cross-site scripting (XSS) in the TechMix Event Countdown Timer Plugin. The vulnerability affects versions of the plugin up to and including 1.4, posing a serious risk to users who have the plugin installed.
The CVSS score for this vulnerability stands at 7.1, indicating a high severity level. This score reflects the potential impact on confidentiality, integrity, and availability, which is assessed as low across the board. However, the vulnerability requires user interaction, adding complexity to exploitation.
Risk to organizations includes exposure to XSS attacks, which can lead to unauthorized actions on behalf of users, theft of sensitive information, and damage to user trust. Given the nature of XSS vulnerabilities, an attacker can craft a malicious link that, if clicked by a user, can execute harmful scripts in the context of the user's browser.
Organizations using this plugin should prioritize patching immediately to mitigate the risk associated with this vulnerability. The developer has deferred the status of this vulnerability, indicating that further evaluation or remediation efforts might be pending.
Vulnerability Details
The vulnerability allows attackers to inject arbitrary scripts into web pages viewed by other users. The core issue lies in the plugin's failure to properly sanitize user inputs, enabling reflected XSS attacks. The vulnerability is linked to CWE-79, which addresses improper neutralization of input during web page generation.
The last published update for this vulnerability was on January 16, 2025, and it has been classified as deferred, which means that it might not currently be under active remediation efforts.
Technical Analysis
The root cause of CVE-2025-23699 is the improper handling of user input, which allows for the execution of malicious scripts. The attack vector is classified as network-based, indicating that an attacker can exploit this vulnerability remotely. The attack complexity is assessed as low, requiring no special privileges to exploit this vulnerability, but it does necessitate user interaction.
In terms of impact, the confidentiality, integrity, and availability of the system are all rated low, meaning that while the vulnerability is serious, the potential damage from a successful attack might be limited in scope if properly contained.
Risk & Impact Analysis
Real-world deployment risk includes the potential for attackers to craft malicious URLs that exploit this vulnerability, leading to compromised user sessions or data theft. The urgency for organizations to address this issue is high, given the potential for exploitation in active environments. With a CVSS score of 7.1, organizations should implement immediate measures to patch the vulnerability.
The blast radius for this vulnerability can be substantial, especially in environments where many users interact with the affected plugin. Organizations should assess their exposure and implement necessary security measures to mitigate the associated risks.
