A critical unrestricted file upload vulnerability in Rotaban allows attackers to upload web shells, leading to full remote code execution.

The application fails to properly validate the file types during the upload process, allowing attackers to upload malicious scripts (web shells) and execute them on the web server.

With a CVSS score of 9.9, this vulnerability is extremely dangerous as it grants attackers the ability to execute arbitrary code with the privileges of the web server. This typically results in full system compromise, data theft, and the establishment of persistent backdoors.

Immediate Action: Upgrade Rotaban to version V2026.06.003 or later immediately to patch the file upload validation logic.

Proactive Monitoring: Scan web directories for newly created executable files or suspicious scripts that may indicate the presence of a web shell.

Compensating Controls: Configure the web server to disable script execution in upload directories and ensure that the web server process runs with limited permissions.

Public Exploit Available: True

The availability of public exploits makes this a high-priority threat. System administrators should prioritize this update and perform a thorough security audit of the server to ensure that no unauthorized web shells have already been deployed.
