A vulnerability exists in ChurchCRM 5.13.0 and prior that allows an attacker to execute arbitrary SQL queries by exploiting a boolean-based blind SQL Injection vulnerability in the EditEventAttendees functionality. The EID parameter is directly concatenated into an SQL query without proper sanitization, making it susceptible to SQL injection attacks. An attacker can manipulate the query, potentially leading to data exfiltration, modification, or deletion. Please note that this vulnerability requires Administrator privileges.
With a CVSS score of 9.3, this vulnerability is classified as critical. Organizations using ChurchCRM should recognize the severity of this issue, as risk to organizations includes unauthorized access to sensitive data and potential disruption of services. Immediate action is required to mitigate the risks associated with this vulnerability.
As of now, there is no known public exploit, but the potential for exploitation remains high due to the nature of the vulnerability. Organizations should prioritize patching immediately to safeguard against potential attacks.
In the following sections, we will explore the details of the vulnerability, its risk and impact, and provide guidance on mitigation and detection.
Vulnerability Details
A vulnerability exists in ChurchCRM 5.13.0 and prior that allows an attacker to execute arbitrary SQL queries by exploiting a boolean-based blind SQL Injection vulnerability in the EditEventAttendees functionality. The EID parameter is directly concatenated into an SQL query without proper sanitization, making it susceptible to SQL injection attacks. An attacker can manipulate the query, potentially leading to data exfiltration, modification, or deletion. This vulnerability requires Administrator privileges.
The vulnerability has a CVSS 4.0 score of 9.3, categorized as critical, indicating that attackers can exploit it easily with low complexity and high potential impact. The attack vector is network-based, meaning it can be exploited remotely without physical access to the system.
Technical Analysis
The root cause of this vulnerability is improper sanitization of the EID parameter. Attackers may leverage this flaw to inject malicious SQL queries into the application's database. Given the low attack complexity and high privileges required, an attacker with Administrator access can easily exploit this vulnerability.
No user interaction is required, thus making it easier for attackers to execute SQL injection attacks. The potential impacts on confidentiality, integrity, and availability are all rated high, reflecting the significant risk this vulnerability poses to organizations.
Risk & Impact Analysis
The risk to organizations includes unauthorized access to sensitive data through data exfiltration, modification, or deletion. The potential for a significant blast radius is present, especially for organizations that manage critical data within ChurchCRM. Organizations should address this vulnerability in their priority patch cycle.
Given the critical nature of the vulnerability and the high CVSS score, organizations should prioritize patching immediately. The potential for exploitation remains high, necessitating swift remediation efforts.
Exploitation Status
Signal | Status |
|---|---|
