CVE-2025-48283 is a critical SQL Injection vulnerability (CWE-89) affecting the Majestic Support product up to version 1.1.0. SQL Injection occurs when user-supplied input is improperly sanitized or neutralized before being incorporated into SQL queries, allowing attackers to manipulate the database queries executed by the application. This vulnerability enables an unauthenticated remote attacker to inject malicious SQL commands due to lack of proper input validation and sanitization. The CVSS 3.1 score of 9.3 indicates a critical severity with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and scope change (S:C). The impact is high on confidentiality (C:H), with no impact on integrity (I:N) and low impact on availability (A:L). The scope change means the vulnerability affects components beyond the initially vulnerable component, potentially compromising the entire system or connected systems. Exploitation could allow attackers to extract sensitive data from the backend database, such as user credentials, personal information, or internal configuration data, without authentication. Although no known exploits are currently reported in the wild, the critical nature and ease of exploitation make this a significant threat. The lack of available patches at the time of publication increases the urgency for mitigation. Majestic Support is a software product likely used for customer support or ticketing systems, which typically store sensitive customer and operational data, making the impact of data leakage or unauthorized access severe. The vulnerability affects all versions up to 1.1.0, with no specific version range provided, indicating a potentially broad exposure for users of this software.

For European organizations, this vulnerability poses a substantial risk to the confidentiality of sensitive customer and operational data managed within Majestic Support systems. Exploitation could lead to unauthorized data disclosure, violating GDPR and other data protection regulations, resulting in legal penalties and reputational damage. The critical severity and network accessibility mean attackers can remotely exploit the vulnerability without authentication or user interaction, increasing the likelihood of attacks. Organizations relying on Majestic Support for customer service or internal support functions may face operational disruptions if attackers leverage the vulnerability to extract data or perform lateral movement within the network. The scope change indicates that exploitation could affect interconnected systems, potentially compromising broader IT infrastructure. This risk is heightened for sectors with stringent data privacy requirements such as finance, healthcare, and government entities in Europe. Additionally, the absence of patches necessitates immediate risk management to prevent data breaches and maintain compliance with European cybersecurity directives.

1. Immediate risk reduction should include deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting Majestic Support endpoints. 2. Conduct a thorough input validation audit on all user inputs processed by Majestic Support, implementing parameterized queries or prepared statements to eliminate direct concatenation of user input into SQL commands. 3. Isolate the Majestic Support application within a segmented network zone with strict access controls to limit potential lateral movement in case of compromise. 4. Monitor logs and network traffic for unusual database query patterns or unexpected outbound data flows indicative of exploitation attempts. 5. Engage with the vendor or community to obtain patches or updates as soon as they become available; if none exist, consider temporary mitigation by disabling vulnerable features or restricting access to the application to trusted IP ranges. 6. Implement strict database user permissions, ensuring the application uses the least privilege principle to minimize data exposure if exploited. 7. Educate internal security teams about this vulnerability to enhance incident response readiness. 8. Perform regular vulnerability scanning and penetration testing focused on SQL injection vectors within the Majestic Support environment.
