This Multi-State Information Sharing and Analysis Center (MS-ISAC) Advisory is being provided to assist agencies and organizations in guarding against the persistent malicious actions of cybercriminals. Multiple vulnerabilities have been discovered in Progress ShareFile. Progress ShareFile is a secure, cloud-based content collaboration and file-sharing platform. It enables businesses to securely exchange documents, manage client workflows, and obtain electronic signatures, with a focus on compliance for industries like finance and healthcare. Successful exploitation of the vulnerabilities, when chained together, could allow attackers to abuse the file upload and extraction functionality to place malicious ASPX webshells in the application’s webroot. Threat Intelligence watchTowr released proof of concept code and a demo publicly for CVE-2026-2699 and CVE-2026-2701 Systems Affected
  • Progress ShareFile versions prior to 5.12.4
Risk
Government: - Large and medium government entities: High - Small government entities: Medium
Businesses: - Large and medium business entities: High - Small business entities: Medium
Home Users: Low
Recommendations
  • Apply appropriate updates provided by Progress software or other vendors which use this software to vulnerable systems immediately after appropriate testing.
  • Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Use vulnerability scanning to find potentially exploitable software vulnerabilities to remediate them.
  • Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Configure separate virtual private cloud (VPC) instances to isolate critical cloud systems.
  • Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.
