MEDIUM 5.3

DescriptionCVE.org

A vulnerability was determined in itsourcecode Construction Management System 1.0. The impacted element is an unknown function of the file /borrowed_equip.php of the component Parameter Handler. This manipulation of the argument emp causes sql injection. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized.

AnalysisAI

SQL injection in itsourcecode Construction Management System 1.0 allows authenticated remote attackers to execute arbitrary SQL queries via the emp parameter in /borrowed_equip.php, potentially compromising data confidentiality and integrity. The vulnerability has a CVSS score of 5.3 with publicly available exploit code; however, exploitation requires valid authentication credentials and does not grant administrative privileges or enable denial of service.

Technical ContextAI

The vulnerability stems from improper input validation in the Parameter Handler component of a PHP-based Construction Management System. The /borrowed_equip.php file fails to sanitize or parameterize the emp parameter before incorporating it into SQL queries, enabling SQL injection attacks classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The affected product is identified by CPE cpe:2.3:a:itsourcecode:construction_management_system, indicating all versions of itsourcecode's Construction Management System are potentially vulnerable. The exploitation vector is network-based with low attack complexity, but requires prior authentication (PR:L per CVSS 4.0 vector).

RemediationAI

Apply the latest security patch from itsourcecode available at https://itsourcecode.com/ or contact the vendor for version-specific patch guidance, as exact patched versions are not specified in available disclosure data. In the interim, implement input validation and prepared statements (parameterized queries) for the emp parameter in /borrowed_equip.php to neutralize SQL injection vectors. Restrict network access to the Construction Management System to trusted internal networks and implement strong authentication mechanisms to reduce the pool of users who can trigger the vulnerability. Monitor database query logs for suspicious SQL patterns as a detective control.
