# Windows iSCSI: link following lets a network attacker gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-122177 (this .md is for agents)

Windows iSCSI resolves a symbolic or file link before accessing a file, so an attacker can redirect that access. The sources say an unauthorized attacker over the network can elevate privileges.

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

## Affected

- vendor:Windows iSCSI affected range not listed fixed no fixed version listed

## How to check

- Check whether the iSCSI Target or Initiator service is running on the Windows machine, for example with `Get-Service MSiSCSI` in PowerShell.
- Confirm the Windows build against Microsoft's security update guide for CVE-2026-122177.
