CVE-2018-1098: Fedoraproject Fedora

High severity, CVSS 8.8. EPSS: 1.2% chance of exploitation in the next 30 days.

A cross-site request forgery flaw was found in etcd 3.3.1 and earlier. An attacker can set up a website that tries to send a POST request to the etcd server and modify a key. Adding a key is done with PUT so it is theoretically safe (can't PUT from an HTML form or such) but POST allows creating in-order keys that an attacker can send.

Affected products

• Fedoraproject Fedora: version 30 only
• Red Hat Etcd: up to and including 3.3.1
