Multiple Vulnerabilities in ResourceSpace

During our assessment of the ResourceSpace code base, we found three new vulnerabilities that could be exploited by an unauthenticated attacker. The most critical is CVE-2021-41765, a pre-auth SQL injection that an attacker can abuse to gain remote code execution (RCE) privileges on the ResourceSpace server.

CVE-2021-27927: CSRF to RCE Chain in Zabbix

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.
