Exploiting this flaw, attackers can bypass intended security mechanisms to upload files outside the designated ‘uploadtemp’ directory through a specially crafted POST request.

Some strings were obfuscated, making the task of reverse engineering the application more challenging.

 If an attacker successfully uploads a file to the web portal’s DocumentRoot, they could leverage specially crafted JSP files to execute arbitrary code on the server, including deploying web shells for persistent access and control.

The vulnerability has been assigned a CVSSv3.1 score of 9.8, categorizing it as critical due to its potential impact on confidentiality, integrity, and availability.

Fortran has addressed this vulnerability by releasing an update for FileCatalyst Workflow. Users are urged to upgrade to version 5.1.6 Build 114 or higher to mitigate the risk associated with CVE-2024-25153.Update Notification

Implications and Recommendations

The publication of a PoC for CVE-2024-25153 underscores the importance of timely patch management and vulnerability assessment within organizations.

Given this vulnerability’s critical nature, Fortra FileCatalyst Workflow users must apply the provided updates without delay.

Additionally, organizations should consider conducting a thorough security review of their web applications and implementing layered security measures to defend against similar threats.
