CVE-ID : CVE-2017-15091
Package : powerdns
Type : access restriction bypass
Remote : Yes
Link : https://security.archlinux.org/AVG-519
The package powerdns before version 4.0.5-1 is vulnerable to access
restriction bypass.
Upgrade to 4.0.5-1.
The problem has been fixed upstream in version 4.0.5.
None.
An issue has been found in the API component of PowerDNS Authoritative
< 4.0.5, where some operations that have an impact on the state of the
server are still allowed even though the API has been configured as
read-only via the ‘api-readonly’ keyword. This missing check allows an
attacker with valid API credentials could flush the cache, trigger a
zone transfer or send a NOTIFY.
A remote, authenticated attacker can flush the cache, trigger a zone
transfer or send a NOTIFY through the API even though it was configured
as read-only.
