Zabbix vulnerability

What happened

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 database data through time-based techniques, potentially leading to session identifier disclosure and administrator account compromise.

Affected versions

Zabbix: 7.0.0 through 7.0.21 (git); 7.2.0 through 7.2.14 (git); 7.4.0 through 7.4.5 (git) Fixed: See vendor advisory.
