CVE-2022-24798 | Insufficient password hash filtering in some IRRd queries and exports

Internet Routing Registry daemon version 4 is an IRR database server, processing IRR objects in the RPSL format. IRRd did not always filter password hashes in query responses relating to `mntner` objects and database exports. This may have allowed adversaries to retrieve some of these hashes, perform a brute-force search for the clear-text passphrase, and use these to make unauthorised changes to affected IRR objects. This issue only affected instances that process password hashes, which means it is limited to IRRd instances that serve authoritative databases. IRRd instances operating solely as mirrors of other IRR databases are not affected. This has been fixed in IRRd 4.2.3 and the main branch. Versions in the 4.1.x series never were affected. Users of the 4.2.x series are strongly recommended to upgrade. There are no known workarounds for this issue.
