CVE-2025-23723 is classified as a high-severity vulnerability due to its CVSS score of 7.1. This vulnerability allows improper neutralization of input during web page generation, specifically resulting in reflected Cross-site Scripting (XSS) in the Plestar Directory Listing plugin. The issue impacts versions of the plugin from n/a through version 1.0.
The reflected XSS vulnerability can be exploited by attackers to execute arbitrary scripts in the context of a user's session, potentially leading to unauthorized actions on behalf of the user. Given its nature, organizations using this plugin are at risk of session hijacking, data theft, and other malicious activities.
As this vulnerability was published on January 23, 2025, organizations should prioritize remediation actions immediately. Even though it is currently classified as deferred, the potential impact on users' security and privacy necessitates prompt attention.
The urgency for defenders is clear: organizations should implement the necessary patches or updates to mitigate the risk associated with this vulnerability effectively.
Vulnerability Details
The official description of CVE-2025-23723 indicates that it allows for reflected XSS through improper input neutralization in the Plestar Directory Listing plugin. The CVSS score of 7.1 categorizes this as a high-severity vulnerability, which reflects its potential impact on confidentiality, integrity, and availability.
This vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation, leading to XSS. The attack vector is network-based with low complexity, requiring no privileges and necessitating user interaction.
The vulnerability is documented as affecting Plestar Directory Listing versions up to and including 1.0. The publication date of the vulnerability allows security teams to track and manage their remediation efforts effectively.
Technical Analysis
The root cause of CVE-2025-23723 lies in the insufficient filtering and encoding of user-provided input. An attacker can craft a malicious link that, when clicked by a user, injects a script into the web page, executing it within the user's browser context.
The attack vector is primarily network-based, allowing attackers to exploit users connecting to the affected service. The complexity of the attack is low, as it only requires the user to click a malicious link.
There are no specific privileges required for the attack, and user interaction is necessary, as the user must be tricked into clicking the malicious link. The impacts on confidentiality, integrity, and availability are all categorized as low, but the potential for exploitation remains significant.
Risk & Impact Analysis
Risk to organizations includes potential exploitation of user accounts, leading to data theft, unauthorized actions, and damage to reputation. The blast radius of such an attack could spread quickly if users are not aware of the malicious nature of the links they are clicking.
Given the CVSS score of 7.1, organizations must treat this vulnerability with high urgency. While it is currently not included in the KEV catalog, the potential for exploitation remains, and organizations should be proactive in their risk management strategies.
The EPSS score of 0.00178 indicates a very low probability of exploitation in the wild. However, this does not diminish the necessity for patching, as the consequences of exploitation can still be severe.
