zabbix CVEs

An authenticated Zabbix user (User role) with template/host write permissions is able to create objects via the configuration.import API. This can lead to confidentiality loss by…

An authenticated Zabbix user (including Guest) is able to cause disproportionate CPU load on the webserver by sending specially crafted parameters to /imgstore.php, leading to pot…

An authenticated Zabbix Super Admin can exploit the oauth.authorize action to read arbitrary files from the webserver leading to potential confidentiality loss.

A regular Zabbix user with no permission to the Monitoring -> Problems view is still able to call the problem.view.refresh action and therefore still retrieve a list of active pro…

A regular Zabbix user can search other users in their user group via Zabbix API by select fields the user does not have access to view. This allows data-mining some field values t…

The LDAP 'Bind password' value cannot be read after saving, but a Super Admin account can leak it by changing LDAP 'Host' to a rogue LDAP server. To mitigate this, the 'Bind passw…

Due to a bug in Zabbix API, the hostprototype.get method lists all host prototypes to users that do not have any user groups assigned to them.

Zabbix server is vulnerable to a DoS vulnerability due to uncontrolled resource exhaustion. An attacker can send specially crafted requests to the server, which will cause the ser…

The endpoint /zabbix.php?action=export.valuemaps suffers from a Cross-Site Scripting vulnerability via the backurl parameter. This is caused by the reflection of user-supplied dat…

Zabbix API user.get returns all users that share common group with the calling user. This includes media and other information, such as login attempts, etc.

Execution time for an unsuccessful login differs when using a non-existing username compared to using an existing one.

A low privilege (regular) Zabbix user with API access can use SQL injection vulnerability in include/classes/api/CApiService.php to execute arbitrary SQL commands via the groupBy…

A bug in the code allows an attacker to sign a forged zbx_session cookie, which then allows them to sign in with admin permissions.

When exporting media types, the password is exported in the YAML in plain text. This appears to be a best practices type issue and may have no actual impact. The user would need t…
