Business software provider Zoho has urged customers to patch a critical security flaw affecting multiple ManageEngine products.

“We identified a SQL injection vulnerability in our internal framework that would grant all [.] users unauthenticated access to the backend database,” Zoho said.

In September, CISA warned of another critical ManageEngine vulnerability exploited in attacks to gain remote code execution on unpatched servers running PAM360, Access Manager Plus, and Password Manager Pro.

Zoho ManageEngine servers have been under constant targeting in recent years, with Desktop Central instances getting hacked and access to breached organizations’ networks sold on hacking forums starting in July 2020.

Following these extensive attack campaigns, the FBI and CISA issued two joint advisories [1, 2] warning of state-sponsored attackers exploiting ManageEngine bugs to backdoor the networks of critical infrastructure organizations.
