Version 2.12.5 fixes two security vulnerabilities that may lead to privilege escalation for authenticated API users. Other improvements include several bugfixes related to downtimes, downtime notifications, and more reliable connection handling.
Security
- Don't expose the PKI ticket salt via the API. This may lead to privilege escalation for authenticated API users by them being able to request certificates for other identities (CVE-2021-32739)
- Don't expose IdoMysqlConnection, IdoPgsqlConnection, IcingaDB, and ElasticsearchWriter passwords via the API (CVE-2021-32743)
- Windows: Update bundled OpenSSL to version 1.1.1k #8885
Depending on your setup, manual intervention beyond installing the new versions may be required, so please read the more detailed information in the release blog post carefully.
Bugfixes
- Don't send downtime end notification if downtime hasn't started #8877
- Don't let a failed downtime creation block the others #8863
- Support downtimes and comments for checkables with long names #8864
- Trigger fixed downtimes immediately if the current time matches (instead of waiting for the timer) #8889
- Add configurable timeout for full connection handshake #8866
