zabbix_agentd 1.1.4 in ZABBIX before 1.4.3 runs "UserParameter" scripts with gid 0, which might allow local users to gain privileges.

A File Inclusion vulnerability exists in Zabbix 2.0.6 due to inadequate sanitization of request strings in CGI scripts, which could let a remote malicious user execute arbitrary code.

Zabbix Agent 2 Docker plugin does not properly sanitize the 'docker.container_info' parameters when forwarding them to the Docker daemon. An attacker capable of invoking Agent 2 can read arbitrary files from running Docker containers by injecting them via the Docker archive API.

An unauthenticated attacker can exploit the Frontend 'validate' action to blindly instantiate arbitrary PHP classes. The impact depends on environment setup but appears limited at this time.

A low privilege Zabbix user with API access can exploit a blind SQL injection vulnerability in include/classes/api/CApiService.php to execute arbitrary SQL selects via the sortfield parameter. Although query results are not returned directly, an attacker can exfiltrate arbitrary…

Host and event action script input is validated with a regex (set by the administrator), but the validation runs in multiline mode. If ^ and $ anchors are used in user input validation, an injected newline lets authenticated users bypass the check and inject shell commands.

For performance reasons Zabbix Server/Proxy reuses JavaScript (Duktape) contexts (used in script items, JavaScript reprocessing, Webhooks). This can lead to confidentiality loss where a regular (non-super) Zabbix administrator leaks data for hosts they do not have access to. A…

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 potential denial of service.

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 problems.

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 the user does not have access to.

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 password' value is now reset on 'Host' change.
