CVE-2025-9730 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Apartment Management System. The flaw exists in an unspecified function within the /ajax/updateProfile.php file, where the user_id parameter is improperly sanitized. This allows an unauthenticated remote attacker to inject malicious SQL code by manipulating the user_id argument. The vulnerability does not require any privileges or user interaction, making it remotely exploitable over the network. The injection could lead to unauthorized access to the backend database, potentially allowing attackers to read, modify, or delete sensitive data related to apartment management, such as tenant information, payment records, or administrative credentials. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, no authentication required, and partial impact on confidentiality, integrity, and availability. Although no public exploits are currently known to be actively used in the wild, the exploit code has been publicly disclosed, increasing the risk of exploitation by opportunistic attackers. The vulnerability's presence in a critical component responsible for profile updates suggests that attackers could manipulate user data or escalate privileges by exploiting the injection point.

For European organizations using the itsourcecode Apartment Management System version 1.0, this vulnerability poses a significant risk to data confidentiality and integrity. Apartment management systems typically store personally identifiable information (PII) of tenants, financial transaction data, and operational details. Exploitation could lead to data breaches exposing sensitive tenant information, financial fraud, or disruption of property management services. This could result in regulatory non-compliance under GDPR, leading to legal penalties and reputational damage. Additionally, attackers could leverage the vulnerability as a foothold to pivot into broader organizational networks if the system is connected to internal infrastructure. The medium severity rating indicates a moderate but tangible risk, especially for organizations that have not applied any mitigations or patches. Given the remote exploitability without authentication, attackers can target exposed systems over the internet or internal networks, increasing the attack surface.

Since no official patches are currently linked, European organizations should implement immediate compensating controls. These include: 1) Restricting access to the /ajax/updateProfile.php endpoint via network segmentation and firewall rules, limiting it to trusted IP addresses or VPN users only. 2) Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting the user_id parameter. 3) Conducting input validation and sanitization on all user-supplied data, especially user_id, to enforce strict type and format constraints. 4) Monitoring logs for unusual database query patterns or repeated failed attempts targeting the vulnerable endpoint. 5) Planning and prioritizing an update or patch deployment from the vendor once available. 6) Performing regular security assessments and penetration testing focused on injection vulnerabilities. 7) Educating IT staff about the vulnerability and ensuring incident response readiness in case of exploitation attempts.
