CVE-2025-5583 is a critical SQL Injection vulnerability identified in version 1.0 of the CodeAstro Real Estate Management System, specifically within an unspecified function in the /register.php file. SQL Injection vulnerabilities occur when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing attackers to manipulate the database queries executed by the application. In this case, the vulnerability allows remote attackers to inject malicious SQL code without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/PR:N/UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, potentially enabling attackers to extract sensitive data, modify or delete records, or disrupt service availability. Although the CVSS 4.0 base score is 6.9 (medium severity), the description classifies it as critical due to the nature of SQL injection and the lack of any required privileges or user interaction. The vulnerability affects only version 1.0 of the product, and no patches or mitigations have been publicly disclosed yet. No known exploits are reported in the wild at the time of publication, but public disclosure of the exploit code increases the risk of exploitation. The vulnerability does not involve scope changes or advanced attack complexity, making it relatively straightforward to exploit remotely. The lack of authentication or user interaction requirements further elevates the risk profile. Given the product is a Real Estate Management System, the database likely contains sensitive client information, property details, and transaction records, which are valuable targets for attackers.

For European organizations using CodeAstro Real Estate Management System 1.0, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to sensitive personal and financial data of clients, violating GDPR and other data protection regulations, potentially resulting in heavy fines and reputational damage. Attackers could manipulate property listings or transaction data, undermining business integrity and customer trust. Availability impacts could disrupt business operations, causing financial losses. The real estate sector in Europe is highly regulated and data-sensitive, so breaches could trigger regulatory investigations and loss of competitive advantage. Additionally, the remote exploitability without authentication means attackers can target exposed systems over the internet, increasing the attack surface. Organizations relying on this system for client management, property listings, or transaction processing are at risk of data breaches, fraud, and operational disruption.

Immediate mitigation steps include isolating or restricting access to the vulnerable /register.php endpoint, especially from untrusted networks. Organizations should implement Web Application Firewalls (WAFs) with SQL Injection detection and prevention rules tailored to the application’s request patterns. Input validation and parameterized queries should be enforced in the application code to prevent injection, but since no patch is currently available, temporary mitigations are critical. Monitoring database logs and application logs for suspicious query patterns or anomalies can help detect exploitation attempts. Network segmentation to limit database access and applying the principle of least privilege to database accounts can reduce impact. Organizations should engage with CodeAstro for patch availability and apply updates promptly once released. Conducting a thorough security review of the application and related components is advised to identify and remediate similar vulnerabilities. Finally, organizations should prepare incident response plans to address potential data breaches resulting from exploitation.
