The Email Subscribers by Icegram Express plugin for WordPress is vulnerable to SQL Injection via the ‘hash’ parameter in all versions up to, and including, 5.7.20 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The vulnerability has a CVSS score of 9.8, indicating a critical severity level.
Risk to organizations includes unauthorized access to sensitive data, which could lead to data breaches and loss of customer trust. Given the critical nature of this vulnerability, organizations should prioritize patching immediately.
Currently, there is a known exploit available, and while the vulnerability has not been categorized under the Known Exploited Vulnerabilities (KEV) list, it is critical for organizations to assess their exposure and take necessary action.
The vulnerability was published on June 5, 2024, and the urgency for remediation is high given the potential impact it poses. Organizations using the affected plugin must take immediate steps to mitigate risks associated with this vulnerability.
Vulnerability Details
The SQL Injection vulnerability allows attackers to manipulate the SQL query by injecting malicious code through the 'hash' parameter. This vulnerability affects the Email Subscribers by Icegram Express plugin for WordPress, which is widely used for managing email subscriptions.
The CVSS score of 9.8 indicates the vulnerability's critical severity. It has a low attack complexity, requires no privileges, and does not require user interaction. The potential impacts on confidentiality, integrity, and availability are all rated as high.
The vulnerability has been classified under CWE-89, which pertains to SQL Injection flaws.
Technical Analysis
The root cause of this vulnerability lies in insufficient escaping of user-supplied input, specifically in the SQL query that handles the 'hash' parameter. This oversight allows attackers to append arbitrary SQL commands, potentially leading to unauthorized disclosure of sensitive data stored in the database.
The attack vector is network-based, meaning an attacker can exploit the vulnerability remotely. The attack complexity is low, as no special skills or techniques are required to exploit it. Additionally, no privileges are required, making it accessible to unauthenticated users.
Given the nature of the vulnerability, user interaction is not required, which increases the likelihood of exploitation. The impacts on confidentiality, integrity, and availability are all high, representing a significant risk to organizations using the affected plugin.
Risk & Impact Analysis
Organizations deploying the Email Subscribers by Icegram Express plugin face substantial risks. The potential for an attacker to execute arbitrary SQL queries can lead to the exposure of sensitive user data, including personal information and email addresses. This could result in severe reputational damage, regulatory penalties, and loss of customer trust.
The urgency of addressing this vulnerability is underscored by its high CVSS score, indicating critical severity. Organizations should assess their exposure and prioritize patching this vulnerability in their security response plans.
The blast radius of this vulnerability is significant, as it can affect all installations of the affected plugin, making it imperative for organizations to act swiftly.
