Quote:Zimbra webmail server has two flaws that could let an attacker paw through the inbox and outbox of all the employees in all the enterprises that use the immensely popular collaboration tool, researchers say.
In a Tuesday writeup, SonarSource called it a “drastic” situation, given Zimbra’s popularity and the highly sensitive nature of the scads of messages that it handles. According to Zimbra’s site, its email and collaboration tools are used by over 200,000 businesses, over a thousand government and financial institutions, and hundreds of millions of users to exchange emails every day.
“When attackers get access to an employee’s email account, it often has drastic security implications,” according to the report. “Besides the confidential information and documents that are exchanged, an email account is often linked to other sensitive accounts that allow a password reset. Think about it, what could an attacker do with your inbox?”
Well, they’d freely romp through accounts, for one. SonarSource researchers discovered two vulnerabilities in the open-source Zimbra code that can be chained together to give attackers unrestricted access to Zimbra mail servers and to all sent and received emails of all employees.
