## Overview

An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only).

## Affected

- `curl >= 7.33.0, < 7.83.0`
- `debian_linux = 10.0`
- `debian_linux = 11.0`
- `clustered_data_ontap`
- `solidfire_&_hci_management_node`
- `solidfire_&_hci_storage_node`
- `fabric_operating_system`
- `bootstrap_os`
- `h300s_firmware`
- `h500s_firmware`
- `h700s_firmware`
- `h410s_firmware`
- `universal_forwarder >= 8.2.0, < 8.2.12`
- `universal_forwarder >= 9.0.0, < 9.0.6`
- `universal_forwarder = 9.1.0`

## Remediation

Upgrade past the affected range:

- `curl 7.83.0`
- `universal_forwarder 9.0.6`
