CVE-2025-25222 affects the LuxCal Web Calendar, specifically the versions prior to 5.3.3M for MySQL and 5.3.3L for SQLite. This vulnerability allows for SQL injection through the retrieve.php file, which can lead to unauthorized access to sensitive data. The CVSS score for this vulnerability is 9.8, indicating a critical severity level. Organizations using these versions face serious risks as attackers may leverage this vulnerability to delete, alter, or retrieve information from databases.
The SQL injection vulnerability poses a significant threat to the confidentiality, integrity, and availability of data. Given its critical nature, organizations must prioritize patching their LuxCal installations immediately to prevent potential exploitation. The lack of required privileges and user interaction makes this vulnerability particularly dangerous, as attackers can execute their attacks remotely with minimal effort.
As of now, there are no known exploits or public proof of concepts available for this vulnerability. However, the potential impact on organizations is severe, underscoring the necessity of prompt remediation. Organizations should assess their current installations and apply the necessary patches to mitigate this risk.
Organizations should address this vulnerability in their priority patch cycle. The critical nature of this vulnerability and the potential for severe data breaches necessitate immediate attention from all security teams managing LuxCal Web Calendar installations.
Vulnerability Details
The LuxCal Web Calendar prior to 5.3.3M (MySQL version) and prior to 5.3.3L (SQLite version) contains an SQL injection vulnerability in retrieve.php. If this vulnerability is exploited, information in a database may be deleted, altered, or retrieved.
The CVSS score of 9.8 indicates that this vulnerability is critical, with high impacts on confidentiality, integrity, and availability. The attack vector is classified as network, with low attack complexity, and no privileges or user interactions are required.
The affected versions include all versions prior to 5.3.3M for MySQL and 5.3.3L for SQLite. Organizations using these versions should prioritize patching to the latest version.
Technical Analysis
The root cause of this vulnerability lies in improper sanitization of user inputs in the retrieve.php file, allowing attackers to inject malicious SQL code. The attack vector is network-based, which means that an attacker can exploit this vulnerability remotely without physical access to the system.
Attack complexity is low, as no special conditions are required for exploitation. Attackers do not need any privileges or user interaction to carry out the attack. The exploitation can result in high impacts on confidentiality, integrity, and availability, making this a severe risk for affected organizations.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized data manipulation, leading to loss of sensitive information and operational disruption. The blast radius could extend to any organization utilizing the LuxCal Web Calendar, affecting their data integrity and confidentiality.
Given the critical CVSS score and the nature of the vulnerability, organizations should prioritize patching immediately. The urgency for remediation is heightened by the fact that the vulnerability affects widely used versions of the software, and the potential for exploitation could lead to significant reputational and financial damage.
