CVE-2025-24587 is a high-severity vulnerability identified in the Nks Email Subscription Popup plugin, allowing for blind SQL injection. This flaw arises from improper neutralization of special elements used in SQL commands, which can lead to unauthorized access to sensitive data. The vulnerability affects versions of the Email Subscription Popup plugin from an unknown release up to and including version 1.2.23.
With a CVSS score of 7.6, this vulnerability is classified as high severity due to its potential impact on confidentiality, integrity, and availability. Organizations utilizing the affected plugin should be aware that the attack vector is network-based, and high privileges are required for successful exploitation.
Risk to organizations includes the possibility of attackers executing arbitrary SQL commands, potentially exposing sensitive information stored in the database. Given the nature of SQL injection vulnerabilities, the repercussions can be severe, including data leaks and unauthorized access.
Organizations should prioritize patching immediately, especially if they are using the vulnerable versions of the Email Subscription Popup plugin.
Vulnerability Details
The official description of this vulnerability states: 'Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Nks Email Subscription Popup email-subscribe allows Blind SQL Injection. This issue affects Email Subscription Popup: from n/a through <= 1.2.23.'
This vulnerability corresponds to CWE-89, which highlights the improper handling of SQL commands that can lead to SQL injection attacks. The CVSS 3.1 score breakdown indicates that the attack vector is network-based, the attack complexity is low, and high privileges are required for successful exploitation.
The publication date of this vulnerability was January 24, 2025, and it has since been classified as deferred. Organizations are advised to monitor their environments for this specific vulnerability and assess their exposure based on their usage of the affected plugin.
Technical Analysis
The root cause of this vulnerability lies in the failure to properly neutralize special SQL elements, allowing attackers to craft malicious SQL queries. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely without physical access to the affected system.
The attack complexity is categorized as low, indicating that an attacker does not require specialized conditions to successfully exploit the vulnerability. High privileges are required, which means that the attacker needs to authenticate or have elevated access to exploit the SQL injection effectively.
User interaction is not required, allowing attackers to execute their payloads without any action from the user. The impact on confidentiality is rated as high, as sensitive data may be exposed, while integrity is unaffected, and availability impact is low.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-24587 is significant. Organizations using the vulnerable Email Subscription Popup plugin could face data breaches resulting from unauthorized SQL command execution. The high confidentiality impact means that sensitive user data could be compromised, leading to reputational damage and potential legal ramifications.
The potential blast radius is substantial, particularly for organizations with large user bases or those storing sensitive information. Organizations must assess their exposure and urgency regarding remediation, particularly given the high CVSS score and the nature of SQL injection vulnerabilities, which are commonly targeted by attackers.
Given the exploitation potential and the high-risk nature of SQL injections, organizations should schedule remediation in their priority patch cycle to mitigate potential impacts.
