Magento has released security updates to address several vulnerabilities affecting the Magento Commerce software, out of which three vulnerabilities are rated critical:
- PRODSECBUG-2579: Deserialisation of untrusted data - CVE-2020-3716: The vulnerability exists due to insecure input validation when processing serialised data which could lead to arbitrary code execution on the affected system.
- PRODSECBUG-2633: Security Bypass - CVE-2020-3718: The vulnerability exists due to unspecified error relating to security restrictions which will allow a remote attacker to bypass security restrictions and execute arbitrary code on the affected server.
- PRODSECBUG-2660: SQL Injection - CVE-2020-3719: The vulnerability exists due to insufficient sanitisation of user-supplied data which could allow a remote attacker to exploit this vulnerability by sending a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
