Zabbix is an enterprise IT network and application monitoring solution. In a routine review of its source code, we discovered a CSRF (cross-site request forgery) vulnerability in the authentication component of the Zabbix UI. Using this vulnerability, an unauthenticated attacker can take over the Zabbix administrator’s account if the attacker can persuade the Zabbix administrator to follow a malicious link. This vulnerability is exploitable in all browsers even with the default SameSite=Lax cookie protection in place. The vulnerability is fixed in Zabbix versions 4.0.28rc1, 5.0.8rc1, 5.2.4rc1, and 5.4.0alpha1.
LibreNMS is an open source solution for network monitoring based on PHP, MySQL and SNMP. While reviewing its source code, we discovered a second-order SQL injection vulnerability, CVE-2020-35700, in the Dashboard feature. This vulnerability is exploitable by any authenticated user inside LibreNMS. The vulnerability is fixed in LibreNMS 21.1.0.
OrangeHRM is software for Human Resource Management (HRM). In a routine audit of the open source version of OrangeHRM, we discovered a SQL injection vulnerability in the “Buzz” module, an integrated social media tool within the software.
Authenticated low privilege users can use this vulnerability to disclose the full contents of the OrangeHRM database, including sensitive user personal information and password hashes. It’s also possible to execute a denial of service attack to bring down the application.
Mautic is widely used open source software for marketing automation. While researching the application and its source code on Github, we discovered an attack chain whereby an unauthenticated attacker could gain remote code execution privileges on the server hosting Mautic by abusing a stored XSS vulnerability. The issues raised in this post, CVE-2020-35124 and CVE-2020-35125, have been fixed in Mautic 3.2.4.
