What is CVE-2026-39920?

BridgeHead FileStore versions prior to 24A are vulnerable due to the exposure of the Apache Axis2 administration module on network-accessible endpoints using default credentials. This allows unauthenticated attackers to gain access to the admin console, upload malicious Java archives as web services, and execute arbitrary commands on the host system through SOAP requests. Organizations using affected versions must update to version 24A to mitigate the risk of exploitation.

Affected Version(s)

FileStore 0 < 24A

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
