| CVE | Severity | CVSS | Published | Summary |
|---|---|---|---|---|
| CVE-2025-48057 | CRITICAL | 9.3 | May 27, 2025 | Icinga 2 is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. Prior to versions 2.12.12, 2.13.12, and 2.14.6, the VerifyCertificate() function can be tricked into incorrectly treating certificates as valid. This allows an attacker to send a malicious certificate request that is then treated as a renewal of an already existing certificate, resulting in the attacker obtaining a valid certificate that can |
| CVE-2021-32743 | HIGH | 8.8 | Jul 15, 2021 | Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. In versions prior to 2.11.10 and from version 2.12.0 through version 2.12.4, some of the Icinga 2 features that require credentials for external services expose those credentials through the API to authenticated API users with read permissions for the corresponding object types. IdoMysqlConnection and IdoPgsqlConnection (every released version |
| CVE-2018-6535 | HIGH | 8.1 | Feb 27, 2018 | An issue was discovered in Icinga 2.x through 2.8.1. The lack of a constant-time password comparison function can disclose the password to an attacker. |
| CVE-2020-14004 | HIGH | 7.8 | Jun 12, 2020 | An issue was discovered in Icinga2 before v2.12.0-rc1. The prepare-dirs script (run as part of the icinga2 systemd service) executes chmod 2750 /run/icinga2/cmd. /run/icinga2 is under control of an unprivileged user by default. If /run/icinga2/cmd is a symlink, then it will by followed and arbitrary files can be changed to mode 2750 by the unprivileged icinga2 user. |
| CVE-2018-6533 | HIGH | 7.8 | Feb 27, 2018 | An issue was discovered in Icinga 2.x through 2.8.1. By editing the init.conf file, Icinga 2 can be run as root. Following this the program can be used to run arbitrary code as root. This was fixed by no longer using init.conf to determine account information for any root-executed code (a larger issue than CVE-2017-16933). |
| CVE-2018-6532 | HIGH | 7.5 | Feb 27, 2018 | An issue was discovered in Icinga 2.x through 2.8.1. By sending specially crafted (authenticated and unauthenticated) requests, an attacker can exhaust a lot of memory on the server side, triggering the OOM killer. |
| CVE-2017-16933 | HIGH | 7.0 | Nov 24, 2017 | etc/initsystem/prepare-dirs in Icinga 2.x through 2.8.1 has a chown call for a filename in a user-writable directory, which allows local users to gain privileges by leveraging access to the $ICINGA2_USER account for creation of a link. |
| CVE-2018-6534 | MEDIUM | 6.5 | Feb 27, 2018 | An issue was discovered in Icinga 2.x through 2.8.1. By sending specially crafted messages, an attacker can cause a NULL pointer dereference, which can cause the product to crash. |
| CVE-2018-6536 | MEDIUM | 5.5 | Feb 2, 2018 | An issue was discovered in Icinga 2.x through 2.8.1. The daemon creates an icinga2.pid file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for icinga2.pid modification before a root script executes a "kill `cat /pathname/icinga2.pid`" command, as demonstrated by icinga2.init.d.cmake. |
| CVE-2021-32747 | MEDIUM | 5.3 | Jul 12, 2021 | Icinga Web 2 is an open source monitoring web interface, framework, and command-line interface. A vulnerability in which custom variables are exposed to unauthorized users exists between versions 2.0.0 and 2.8.2. Custom variables are user-defined keys and values on configuration objects in Icinga 2. These are commonly used to reference secrets in other configurations such as check commands to be able to authenticate with a service being checked. Icinga Web 2 displays these custom variables to lo |
