CVE-2026-10253: SQL Injection in itsourcecode Online House Rental System 1.0

Technical summary

CVE-2026-10253 is a SQL injection flaw (CWE-89) in itsourcecode Online House Rental System 1.0 affecting the /manage_payment.php endpoint. The ID argument fails to properly sanitize user input before incorporating it into database queries. The attack vector is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L, indicating a network-accessible vulnerability requiring no privileges or user interaction. The underlying weakness is classified as CWE-74 (Improper Neutralization of Special Elements in Output).

Business impact

Organizations deploying itsourcecode Online House Rental System 1.0 face exposure of sensitive payment information, tenant data, and property details. SQL injection attacks could enable attackers to read, modify, or delete database records, compromising tenant privacy and financial transaction integrity. Given the public availability of exploit code, the risk of active exploitation is elevated. Rental platforms may face regulatory penalties, reputational damage, and loss of customer trust if sensitive data is compromised.

Affected systems

The vulnerability affects itsourcecode Online House Rental System version 1.0. Organizations should verify whether this specific version is deployed in their infrastructure. The vulnerability is not known to affect other products or versions based on available information, though patch or upgrade guidance should be obtained directly from itsourcecode.

Exploitability

This vulnerability is readily exploitable. The CVSS score of 7.3 (HIGH) reflects the ease of attack: no authentication is required, the attack complexity is low, no user interaction is necessary, and the vulnerability is remotely accessible. Public exploit code availability significantly increases real-world risk. An attacker needs only network access and knowledge of the vulnerable endpoint to attempt exploitation.

Remediation

Upgrade itsourcecode Online House Rental System to a patched version released after the vulnerability discovery. Verify patch availability directly from itsourcecode's official advisory or support channels. As an interim measure, implement network-level access controls to restrict access to /manage_payment.php to trusted administrative networks only. Input validation and parameterized queries should be implemented if a patch is not immediately available.

Patch guidance

Contact itsourcecode directly or consult their official security advisory for patched version information and deployment instructions. Given the HIGH severity and public exploit availability, patching should be prioritized for immediate deployment. Test patches in a non-production environment before full rollout. If patches are unavailable, implement compensating controls such as Web Application Firewall (WAF) rules to block malicious SQL injection patterns targeting the /manage_payment.php endpoint.

Detection guidance

Monitor web server and application logs for suspicious SQL syntax in HTTP requests targeting /manage_payment.php, particularly in the ID parameter. Look for patterns such as UNION-based queries, Boolean-based blind SQL injection, or time-based payloads. Implement WAF rules to detect and block common SQL injection signatures. Database query logging should be enabled to catch attempted unauthorized data access. Monitor for unexpected database errors or performance anomalies that may indicate active exploitation attempts.

Why prioritize this

This vulnerability merits immediate remediation due to its HIGH CVSS score (7.3), public exploit availability, direct impact on sensitive payment and rental data, and lack of authentication barriers. The combination of network accessibility, low attack complexity, and confidentiality/integrity/availability impact makes it an attractive target for opportunistic attackers. Organizations should treat this as a critical remediation priority.

Risk score, explained

The CVSS 3.1 score of 7.3 reflects a HIGH severity vulnerability due to: (1) Network accessibility requiring no authentication (AV:N, PR:N), (2) Low attack complexity (AC:L) and no user interaction required (UI:N), and (3) Confidentiality, integrity, and availability impact (C:L/I:L/A:L). The unchanged scope (S:U) prevents the score from reaching CRITICAL threshold, but the public exploit availability and real-world impact elevate operational risk significantly beyond the base score.
