Vulnerability Details
The CVE-2025-23523 vulnerability is described in detail as an improper neutralization of input during web page generation, leading to the potential for reflected Cross-site Scripting (XSS). This vulnerability affects the HSS Embed Streaming Video plugin from n/a through version 3.23.
The CVSS v3.1 score for this vulnerability is 7.1, classified as high severity, indicating a significant risk to affected systems. The attack vector is classified as NETWORK, with low attack complexity and no privileges required for exploitation. User interaction is required to trigger the vulnerability, and it has a changed scope with low impacts on confidentiality, integrity, and availability.
The vulnerability is also associated with CWE-79, which pertains to improper neutralization of input. Organizations should be aware of the potential for this vulnerability to compromise web applications.
Technical Analysis
The root cause of CVE-2025-23523 stems from insufficient input validation in the HSS Embed Streaming Video plugin. Attackers can exploit this vulnerability by crafting malicious input that is not properly sanitized, allowing the execution of arbitrary scripts in a user's browser.
The attack vector is primarily network-based, which means an attacker can exploit the vulnerability remotely. The attack complexity is assessed as low, indicating that minimal technical skill is required to exploit the vulnerability. No privileges are required for exploitation, and user interaction is necessary, as the victim must visit a maliciously crafted link.
The impact on confidentiality, integrity, and availability is categorized as low, which means while the exploitation may not lead to severe system failures, it can lead to unauthorized access to user data and manipulation of user sessions.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-23523 is significant, as reflected XSS vulnerabilities can be exploited by attackers to hijack user sessions or steal sensitive information. Given that the vulnerability affects widely used web applications, the potential blast radius is considerable.
Organizations should consider the impact of this vulnerability on their operations and prioritize remediation efforts accordingly. The urgency assessment based on the CVSS score indicates that this vulnerability should be addressed in priority patch cycles.
