CVE-2024-49369 1 Icinga 1 Icinga Web 2 2025-11-03 9.8 Critical
Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. The TLS certificate validation in all Icinga 2 versions starting from 2.4.0 was flawed, allowing an attacker to impersonate both trusted cluster nodes as well as any API users that use TLS client certificates for authentication (ApiUser objects with the client_cn attribute set). This vulnerability has been fixed in v2.14.3, v2.13.10, v2.12.11, and v2.11.12.
CVE-2021-37698 2 Debian, Icinga 2 Debian Linux, Icinga 2025-11-03 7.5 High
Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. In versions 2.5.0 through 2.13.0, ElasticsearchWriter, GelfWriter, InfluxdbWriter and Influxdb2Writer do not verify the server's certificate despite a certificate authority being specified. Icinga 2 instances which connect to any of the mentioned time series databases (TSDBs) using TLS over a spoofable infrastructure should immediately upgrade to version 2.13.1, 2.12.6, or 2.11.11 to patch the issue. Such instances should also change the credentials (if any) used by the TSDB writer feature to authenticate against the TSDB. There are no workarounds aside from upgrading.
CVE-2021-32743 2 Debian, Icinga 2 Debian Linux, Icinga 2025-11-03 8.8 High
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) exposes the password of the user used to connect to the database. IcingaDB (added in 2.12.0) exposes the password used to connect to the Redis server. ElasticsearchWriter (added in 2.8.0)exposes the password used to connect to the Elasticsearch server. An attacker who obtains these credentials can impersonate Icinga to these services and add, modify and delete information there. If credentials with more permissions are in use, this increases the impact accordingly. Starting with the 2.11.10 and 2.12.5 releases, these passwords are no longer exposed via the API. As a workaround, API user permissions can be restricted to not allow querying of any affected objects, either by explicitly listing only the required object types for object query permissions, or by applying a filter rule.
CVE-2021-32739 2 Debian, Icinga 2 Debian Linux, Icinga 2025-11-03 8.8 High
Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. From version 2.4.0 through version 2.12.4, a vulnerability exists that may allow privilege escalation for authenticated API users. With a read-ony user's credentials, an attacker can view most attributes of all config objects including `ticket_salt` of `ApiListener`. This salt is enough to compute a ticket for every possible common name (CN). A ticket, the master node's certificate, and a self-signed certificate are enough to successfully request the desired certificate from Icinga. That certificate may in turn be used to steal an endpoint or API user's identity. Versions 2.12.5 and 2.11.10 both contain a fix the vulnerability. As a workaround, one may either specify queryable types explicitly or filter out ApiListener objects.
CVE-2025-61909 1 Icinga 1 Icinga 2025-10-29 4.4 Medium
Icinga 2 is an open source monitoring system. From 2.10.0 to before 2.15.1, 2.14.7, and 2.13.13, the safe-reload script (also used during systemctl reload icinga2) and logrotate configuration shipped with Icinga 2 read the PID of the main Icinga 2 process from a PID file writable by the daemon user, but send the signal as the root user. This can allow the Icinga user to send signals to processes it would otherwise not permitted to. A fix is included in the following Icinga 2 versions: 2.15.1, 2.14.7, and 2.13.13.
CVE-2025-61789 1 Icinga 2 Icinga, Icinga Web 2 2025-10-21 5.3 Medium
Icinga DB Web provides a graphical interface for Icinga monitoring. Before 1.1.4 and 1.2.3, an authorized user with access to Icinga DB Web, can use a custom variable in a filter that is either protected by icingadb/protect/variables or hidden by icingadb/denylist/variables, to guess values assigned to it. Versions 1.1.4 and 1.2.3 respond with an error if such a custom variable is used.
CVE-2025-61908 1 Icinga 1 Icinga 2025-10-21 N/A
Icinga 2 is an open source monitoring system. From 2.10.0 to before 2.15.1, 2.14.7, and 2.13.13, when creating an invalid reference, such as a reference to null, dereferencing results in a segmentation fault. This can be used by any API user with access to an API endpoint that allows specifying a filter expression to crash the Icinga 2 daemon. A fix is included in the following Icinga 2 versions: 2.15.1, 2.14.7, and 2.13.13.
CVE-2025-61907 1 Icinga 1 Icinga 2025-10-21 N/A
Icinga 2 is an open source monitoring system. In Icinga 2 versions 2.4 through 2.15.0, filter expressions provided to the various /v1/objects endpoints could access variables or objects that would otherwise be inaccessible for the user. This allows authenticated API users to learn information that should be hidden from them, including global variables not permitted by the variables permission and objects not permitted by the corresponding objects/query permissions. The vulnerability is fixed in versions 2.15.1, 2.14.7, and 2.13.13.
CVE-2025-27404 1 Icinga 1 Icinga Web 2 2025-08-01 7.7 High
Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. A vulnerability in versions prior to 2.11.5 and 2.12.13 allows an attacker to craft a URL that, once visited by any user, allows to embed arbitrary Javascript into Icinga Web and to act on behalf of that user. This issue has been resolved in versions 2.11.5 and 2.12.3 of Icinga Web 2. As a workaround, those who have Icinga Web 2.12.2 may enable a content security policy in the application settings.

Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. A vulnerability in versions prior to 2.11.5 and 2.12.13 allows an attacker to craft a URL that, once visited by any user, allows to embed arbitrary Javascript into Icinga Web and to act on behalf of that user. This issue has been resolved in versions 2.11.5 and 2.12.3 of Icinga Web 2. As a workaround, those who have Icinga Web 2.12.2 may enable a content security policy in the application settings.
CVE-2025-27609 1 Icinga 1 Icinga Web 2 2025-08-01 5.4 Medium
Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. A vulnerability in versions prior to 2.11.5 and 2.12.13 allows an attacker to craft a request that, once transmitted to a victim's Icinga Web, allows to embed arbitrary Javascript into it and to act on behalf of that user. This issue has been resolved in versions 2.11.5 and 2.12.3 of Icinga Web 2. As a workaround, those who have Icinga Web 2.12.2 may enable a content security policy in the application settings. Any modern browser with a working CORS implementation also sufficiently guards against the vulnerability.
CVE-2025-30164 1 Icinga 1 Icinga Web 2 2025-08-01 4.1 Medium
Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. A vulnerability in versions prior to 2.11.5 and 2.12.13 vulnerability allows an attacker to craft a URL that, once visited by an authenticated user (or one that is able to authenticate), allows to manipulate the backend to redirect the user to any location. This issue has been resolved in versions 2.11.5 and 2.12.3 of Icinga Web 2. No known workarounds are available.
CVE-2024-24820 1 Icinga 1 Icinga 2025-06-17 8.3 High
Icinga Director is a tool designed to make Icinga 2 configuration handling easy. Not any of Icinga Director's configuration forms used to manipulate the monitoring environment are protected against cross site request forgery (CSRF). It enables attackers to perform changes in the monitoring environment managed by Icinga Director without the awareness of the victim. Users of the map module in version 1.x, should immediately upgrade to v2.0. The mentioned XSS vulnerabilities in Icinga Web are already fixed as well and upgrades to the most recent release of the 2.9, 2.10 or 2.11 branch must be performed if not done yet. Any later major release is also suitable. Icinga Director will receive minor updates to the 1.8, 1.9, 1.10 and 1.11 branches to remedy this issue. Upgrade immediately to a patched release. If that is not feasible, disable the director module for the time being.
CVE-2024-24819 1 Icinga 1 Icingaweb2-module-incubator 2025-05-15 5.3 Medium
icingaweb2-module-incubator is a working project of bleeding edge Icinga Web 2 libraries. In affected versions the class `gipfl\Web\Form` is the base for various concrete form implementations [1] and provides protection against cross site request forgery (CSRF) by default. This is done by automatically adding an element with a CSRF token to any form, unless explicitly disabled, but even if enabled, the CSRF token (sent during a client's submission of a form relying on it) is not validated. This enables attackers to perform changes on behalf of a user which, unknowingly, interacts with a prepared link or website. The version 0.22.0 is available to remedy this issue. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2022-24715 1 Icinga 1 Icinga Web 2 2025-04-23 8.5 High
Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. Authenticated users, with access to the configuration, can create SSH resource files in unintended directories, leading to the execution of arbitrary code. This issue has been resolved in versions 2.8.6, 2.9.6 and 2.10 of Icinga Web 2. Users unable to upgrade should limit access to the Icinga Web 2 configuration.
CVE-2022-24716 1 Icinga 1 Icinga Web 2 2025-04-23 7.5 High
Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. Unauthenticated users can leak the contents of files of the local system accessible to the web-server user, including `icingaweb2` configuration files with database credentials. This issue has been resolved in versions 2.9.6 and 2.10 of Icinga Web 2. Database credentials should be rotated.
CVE-2022-24714 1 Icinga 1 Icinga Web 2 2025-04-23 5.3 Medium
Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. Installations of Icinga 2 with the IDO writer enabled are affected. If you use service custom variables in role restrictions, and you regularly decommission service objects, users with said roles may still have access to a collection of content. Note that this only applies if a role has implicitly permitted access to hosts, due to permitted access to at least one of their services. If access to a host is permitted by other means, no sensible information has been disclosed to unauthorized users. This issue has been resolved in versions 2.8.6, 2.9.6 and 2.10 of Icinga Web 2.
CVE-2017-16882 1 Icinga 1 Icinga 2025-04-20 N/A
Icinga Core through 1.14.0 initially executes bin/icinga as root but supports configuration options in which this file is owned by a non-root account (and similarly can have etc/icinga.cfg owned by a non-root account), which allows local users to gain privileges by leveraging access to this non-root account, a related issue to CVE-2017-14312. This also affects bin/icingastats, bin/ido2db, and bin/log2ido.
CVE-2017-16933 1 Icinga 1 Icinga 2025-04-20 N/A
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-2015-8010 3 Icinga, Opensuse, Opensuse Project 3 Icinga, Leap, Leap 2025-04-20 N/A
Cross-site scripting (XSS) vulnerability in the Classic-UI with the CSV export link and pagination feature in Icinga before 1.14 allows remote attackers to inject arbitrary web script or HTML via the query string to cgi-bin/status.cgi.
