CVE-2025-11078 is a medium-severity vulnerability affecting version 1.0 of the itsourcecode Open Source Job Portal. The vulnerability exists in the /admin/user/controller.php endpoint, specifically in the 'photos' action, where the 'photo' argument can be manipulated to perform an unrestricted file upload. This flaw allows an attacker to remotely upload arbitrary files without proper validation or restrictions. Since the vulnerability is exploitable remotely without authentication or user interaction, it poses a significant risk. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no authentication required but low privileges needed, no user interaction, and partial impact on confidentiality, integrity, and availability. The exploit code is publicly available, increasing the likelihood of exploitation, although no known active exploitation in the wild has been reported yet. The unrestricted upload can lead to arbitrary code execution, web shell deployment, or defacement, potentially compromising the entire web server and backend systems. Given that the affected software is an open source job portal, organizations using it to manage recruitment or candidate data are at risk of data breaches, service disruption, and reputational damage.

For European organizations, this vulnerability could have serious consequences, especially for those relying on the itsourcecode Open Source Job Portal for recruitment and HR processes. Successful exploitation could lead to unauthorized access to sensitive candidate and employee data, violating GDPR requirements and resulting in regulatory penalties. The ability to upload arbitrary files remotely can enable attackers to execute malicious code, pivot within the network, and disrupt business operations. This could impact availability of recruitment services, delay hiring processes, and damage organizational reputation. Additionally, compromised servers could be used as a foothold for further attacks on internal networks or as part of botnets. The medium severity rating suggests moderate but tangible risk, particularly for organizations with limited security controls or those that have not applied mitigations. The public availability of exploit code increases the urgency for European entities to address this vulnerability promptly.

Organizations should immediately audit their use of the itsourcecode Open Source Job Portal version 1.0 and plan to upgrade to a patched version once available. In the absence of an official patch, implement strict input validation and file type restrictions on the 'photo' upload functionality to prevent arbitrary file uploads. Employ web application firewalls (WAFs) with rules to detect and block suspicious upload attempts targeting the /admin/user/controller.php endpoint. Restrict access to the admin interface by IP whitelisting or VPN to reduce exposure. Monitor server logs for unusual file upload activity or unexpected file types in upload directories. Conduct regular security assessments and penetration tests focusing on file upload mechanisms. Additionally, isolate the job portal server from critical internal networks to limit lateral movement in case of compromise. Backup critical data regularly and have an incident response plan ready to address potential exploitation.
