CVE-2025-10460 identifies a critical SQL Injection vulnerability in BEIMS Contractor Web, specifically version 5.7.139, a legacy contractor management web application no longer supported or patched by its vendor. The vulnerability stems from improper input validation (CWE-20) on the /BEIMSWeb/contractor.asp endpoint, which processes user-supplied parameters without adequate sanitization. This allows unauthenticated attackers to inject arbitrary SQL commands directly into the backend database queries. Successful exploitation can lead to unauthorized retrieval, modification, or deletion of sensitive data stored within the database, compromising confidentiality, integrity, and potentially availability. The vulnerability requires the endpoint to be exposed to the internet but does not require any authentication or user interaction, increasing the attack surface and ease of exploitation. No official patches or updates are currently available, and all versions should be treated as vulnerable until vendor confirmation. The CVSS 4.0 score of 9.4 reflects the critical nature of this flaw, with network attack vector, low attack complexity, no privileges required, no user interaction, and high impact on confidentiality and integrity. The lack of vendor support means organizations must rely on compensating controls such as network segmentation, web application firewalls, and migration strategies. Given the product’s legacy status, many organizations may still rely on it for contractor management, making this vulnerability a significant risk for data breaches and operational impact.

For European organizations, this vulnerability poses a severe risk to the confidentiality and integrity of sensitive contractor and project data managed within BEIMS Contractor Web. Exploitation could lead to unauthorized disclosure of personal, financial, or operational information, potentially violating GDPR and other data protection regulations. Integrity compromise could allow attackers to alter records, disrupt contractor workflows, or inject malicious data, leading to operational disruptions and loss of trust. Availability impacts, while less likely, could occur if attackers execute destructive SQL commands. The lack of vendor patches increases the risk of prolonged exposure, especially for organizations with internet-facing contractor management portals. This could result in regulatory penalties, reputational damage, and financial losses. European critical infrastructure sectors and large enterprises relying on BEIMS Contractor Web for contractor oversight are particularly vulnerable. The ease of exploitation without authentication or user interaction further elevates the threat level, making timely mitigation essential.

1. Immediately assess and identify all instances of BEIMS Contractor Web in your environment, focusing on version 5.7.139 and earlier. 2. Restrict or disable internet exposure of the /BEIMSWeb/contractor.asp endpoint by implementing network segmentation and access controls, limiting access to trusted internal networks only. 3. Deploy and configure web application firewalls (WAFs) with specific SQL Injection detection and prevention rules tailored to the BEIMS Contractor Web traffic patterns. 4. Conduct thorough input validation and sanitization at any custom integration points or proxy layers if possible, to block malicious payloads. 5. Monitor logs and network traffic for unusual SQL query patterns or suspicious access attempts targeting the vulnerable endpoint. 6. Develop and execute a migration plan to replace BEIMS Contractor Web with a supported, actively maintained contractor management solution. 7. If immediate replacement is not feasible, consider deploying virtual patching techniques via WAFs or reverse proxies to mitigate exploitation risk. 8. Educate IT and security teams about the vulnerability specifics and ensure incident response plans include scenarios involving SQL Injection attacks on legacy web applications.
