# arraynetworks arrayos ag: Array Networks Array AG Series and vxAG (9.4.0.481 and earlier) allow remote code execution

Array Networks AG and vxAG ArrayOS SSL VPN appliances have a missing authentication check on a critical function. An unauthenticated attacker can read local files and execute code on the gateway.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Array Networks AG/vxAG ArrayOS affected ? fixed ?
- vendor:arraynetworks arrayos ag affected <= 9.4.0.481 fixed ?

## From the sources

Array Networks Array AG Series and vxAG (9.4.0.481 and earlier) allow remote code execution. An attacker can browse the filesystem on the SSL VPN gateway using a flags attribute in an HTTP header without authentication. The product could then be exploited through a vulnerable URL. The 2023-03-09 vendor advisory stated "a new Array AG release with the fix will be available soon."
