BSD Portsicinga2 -- Improper access control for JSON-RPC update certificate messages

Updating the trusted CA allows an attacker to impersonate a trusted node, allowing them to take control over the node. Any Icinga 2 …
Affected versions
- icinga2 < 2.16.2
By system
0 still vulnerable, 1 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
| System | Port | Version | State | Fixed |
|---|---|---|---|---|
| FreeBSD | net-mgmt/icinga2 | 2.16.5_1 | fixed | (2 days after) |
| OpenBSD | net/icinga/core2 | 2.16.5p0v0 | out of range, by version | |
| NetBSD | net/icinga2 | 2.16.5nb2 | not listed |
