CVE-2025-11101 identifies a SQL injection vulnerability in itsourcecode Open Source Job Portal version 1.0, located in the /jobportal/admin/company/index.php?view=edit script. The vulnerability arises from improper sanitization of the 'ID' parameter, which is used in SQL queries without adequate validation or parameterization. This allows an unauthenticated remote attacker to inject malicious SQL commands by manipulating the 'ID' argument, potentially extracting, modifying, or deleting data from the backend database. The attack vector requires no authentication or user interaction, making it straightforward to exploit remotely. The vulnerability impacts confidentiality, integrity, and availability at a low to moderate level, as indicated by the CVSS 4.0 base score of 6.9. The exploit code has been publicly disclosed, increasing the likelihood of exploitation. No official patches or fixes have been published yet, and no active exploitation has been reported. The vulnerability is critical for organizations relying on this open-source job portal, especially those exposing administrative interfaces to the internet, as attackers could leverage this flaw to compromise sensitive recruitment data or disrupt service availability.

For European organizations, the SQL injection vulnerability poses risks including unauthorized data disclosure, data tampering, and potential service disruption. Recruitment platforms often handle sensitive personal data such as applicant resumes, contact details, and employment history, which could be exposed or altered. Attackers exploiting this flaw could gain insights into internal company structures or manipulate job postings, undermining trust and compliance with data protection regulations like GDPR. Additionally, compromised portals could be used as pivot points for further network intrusion. The public availability of exploit code increases the urgency for mitigation. Organizations with publicly accessible administrative portals are particularly vulnerable, as the attack requires no authentication. The impact extends to reputational damage and potential legal consequences due to data breaches.

To mitigate CVE-2025-11101, organizations should immediately implement strict input validation and sanitization on the 'ID' parameter within the affected PHP script. Employing parameterized queries or prepared statements will prevent SQL injection by separating code from data. Restrict access to the /jobportal/admin/company/index.php endpoint using network-level controls such as IP whitelisting or VPN access to limit exposure. Monitor web server and application logs for suspicious query patterns indicative of injection attempts. If possible, upgrade to a patched version once released by the vendor or apply community-provided patches. Conduct a thorough security audit of the entire job portal application to identify and remediate similar injection flaws. Additionally, implement web application firewalls (WAFs) with rules targeting SQL injection signatures to provide an additional defensive layer. Regular backups and incident response plans should be in place to recover from potential data compromise.
