CVE-2025-11101 is a SQL Injection vulnerability identified in version 1.0 of the itsourcecode Open Source Job Portal, specifically within the /jobportal/admin/company/index.php file when accessed with the 'view=edit' parameter. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, allowing an attacker to manipulate the SQL query executed by the application. This flaw enables remote attackers to inject malicious SQL code without requiring authentication or user interaction, potentially leading to unauthorized data access, data modification, or disruption of the database's integrity and availability. The vulnerability has a CVSS 4.0 base score of 6.9, categorized as medium severity, reflecting its network attack vector, low attack complexity, and no privileges or user interaction required. Although no known exploits are currently observed in the wild, the public availability of proof-of-concept code increases the risk of exploitation. The vulnerability impacts the confidentiality, integrity, and availability of the affected system's data, as attackers may extract sensitive information, alter records, or cause denial of service through crafted SQL payloads. Given that the affected product is an open-source job portal, it is likely deployed by organizations managing recruitment or employment services, which may contain personal and corporate data.

For European organizations using the itsourcecode Open Source Job Portal 1.0, this vulnerability poses a significant risk to sensitive personal data and corporate information stored within the job portal database. Exploitation could lead to unauthorized disclosure of applicant and employee data, manipulation of job postings or company profiles, and potential disruption of recruitment operations. This could result in reputational damage, regulatory non-compliance (notably with GDPR), financial losses, and legal liabilities. The remote, unauthenticated nature of the attack increases the threat surface, especially for organizations exposing the job portal's administrative interface to the internet. Additionally, compromised portals could serve as pivot points for further network intrusion or lateral movement within the organization’s IT environment. The medium severity rating suggests a moderate but tangible risk that requires timely remediation to prevent exploitation.

To mitigate this vulnerability, organizations should immediately review and sanitize all user inputs, especially the 'ID' parameter in the /jobportal/admin/company/index.php?view=edit endpoint, using parameterized queries or prepared statements to prevent SQL injection. Applying input validation and employing a web application firewall (WAF) with SQL injection detection rules can provide additional protection. Since no official patch is currently available, organizations should consider temporarily restricting access to the affected administrative interface via network segmentation or VPN access controls to limit exposure. Regularly monitoring logs for suspicious SQL query patterns and anomalous access attempts is recommended. Organizations should also plan to upgrade to a patched version once released or consider alternative job portal solutions with active security maintenance. Conducting security audits and penetration testing focused on injection flaws will help identify residual risks.
