CVE-2025-23942 is a critical vulnerability classified as an unrestricted upload of file with dangerous type, specifically affecting the WP Load Gallery plugin. This issue allows attackers to upload a web shell to a web server, potentially compromising the entire system. The severity of this vulnerability is underscored by its CVSS score of 9.1, indicating a critical risk to organizations.
Risk to organizations includes unauthorized access to sensitive data, potential defacement of web applications, and the ability to execute arbitrary commands on the server. The exploitation status is currently marked as deferred, meaning that while it has been identified as a risk, it may not be actively exploited at this moment. However, organizations should prioritize patching immediately to mitigate this risk.
The vulnerability affects WP Load Gallery versions from n/a up to and including 2.1.6. Given the potential impact of this vulnerability, organizations using this plugin should take immediate action to update their installations or apply available patches.
Organizations are urged to implement security best practices, such as regular updates and security assessments, to prevent similar vulnerabilities in the future.
Vulnerability Details
The vulnerability allows for unrestricted file uploads, which can lead to the execution of arbitrary code. Specifically, it pertains to the WP Load Gallery plugin version up to 2.1.6.
This vulnerability is categorized under CWE-434, which indicates a weakness related to file upload mechanisms. The CVSS score of 9.1 signifies the critical nature of the risk, indicating high potential for damage.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation of file uploads, allowing attackers to bypass security controls. The attack vector is classified as network-based, meaning that remote attackers can exploit this vulnerability without physical access to the server.
The attack complexity is low, and high privileges are required for exploitation, which may limit the number of potential attackers to those with access to the system. User interaction is not required to exploit this vulnerability, making it even more dangerous.
The impacts on confidentiality, integrity, and availability are all rated high, indicating that successful exploitation could lead to significant data breaches and service disruptions.
Risk & Impact Analysis
Deploying the WP Load Gallery plugin without addressing this vulnerability poses a severe risk to organizations. Attackers could exploit this vulnerability to gain unauthorized access to sensitive data and potentially control the server.
The potential blast radius is significant, as any web server utilizing this plugin may be affected. Organizations should evaluate their exposure and prioritize remediation efforts based on the criticality of this vulnerability.
Given its high CVSS score and the potential for exploitation, organizations must address this vulnerability in their patch management cycle.
