CVE-2025-11078 is a medium-severity vulnerability affecting itsourcecode Open Source Job Portal version 1.0. The vulnerability resides in the /admin/user/controller.php endpoint, specifically in the 'photos' action parameter. The flaw allows an attacker to manipulate the 'photo' argument to perform an unrestricted file upload. This means that an attacker can upload arbitrary files, including potentially malicious scripts or executables, without proper validation or restriction. The vulnerability can be exploited remotely without requiring user interaction or authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:L). The CVSS score of 5.3 reflects a moderate risk, considering the ease of exploitation and the potential impact on confidentiality, integrity, and availability. Although the vulnerability requires low privileges (PR:L), no user interaction or authentication is needed, which lowers the barrier for exploitation. The unrestricted upload can lead to remote code execution, data compromise, or service disruption if the uploaded files are executed or accessed by the system. No official patches or fixes have been published yet, and while no known exploits are reported in the wild, a public exploit is available, increasing the risk of active exploitation. This vulnerability is particularly critical for organizations using this specific open source job portal software, as it can serve as an entry point for attackers to compromise the underlying server and network infrastructure.

For European organizations deploying the itsourcecode Open Source Job Portal 1.0, this vulnerability poses a significant security risk. Successful exploitation could lead to unauthorized access to sensitive user data, including personal information of job applicants and employers, which may violate GDPR and other data protection regulations. Furthermore, attackers could leverage the unrestricted upload to deploy web shells or malware, enabling lateral movement within the network, data exfiltration, or disruption of services. This could damage organizational reputation, lead to financial losses, and incur regulatory penalties. The impact is heightened for public sector entities, recruitment agencies, and large enterprises relying on this portal for critical hiring processes. Additionally, the ability to exploit this remotely without authentication increases the attack surface, making it easier for threat actors to target vulnerable installations across Europe. The lack of an official patch means organizations must rely on mitigation strategies until a fix is available, increasing exposure time.

1. Immediate mitigation should include restricting access to the /admin/user/controller.php endpoint via network controls such as IP whitelisting or VPN-only access to limit exposure to trusted administrators. 2. Implement web application firewall (WAF) rules to detect and block suspicious file upload attempts, especially those targeting the 'photo' parameter. 3. Enforce strict server-side validation and sanitization of uploaded files, including checking file types, sizes, and content signatures to prevent execution of malicious files. 4. Disable execution permissions on directories used for file uploads to prevent uploaded files from being executed as code. 5. Monitor server logs and upload directories for unusual activity or presence of unexpected files. 6. If possible, temporarily disable the photo upload functionality until a patch is released. 7. Regularly update and patch the job portal software once the vendor releases a fix. 8. Conduct security audits and penetration tests focusing on file upload mechanisms to identify similar vulnerabilities. 9. Educate administrators on the risks of unrestricted file uploads and the importance of applying security best practices.
