CVE-2019-12924: MailEnable Enterprise Premium lets strangers read files, steal passwords

CVE-2019-12924 · published 7 years ago
Summary

MailEnable Enterprise Premium version 10.23 lets anyone on the network read any file on the server because of a mis‑configured XML handler. The server also stores all user passwords in a plain‑text file, so an attacker could copy those passwords, including admin accounts. Update to the latest version or apply the vendor’s patch and protect the password file with encryption.

MailEnable Enterprise Premium 10.23 was vulnerable to XML External Entity Injection (XXE) attacks that could be exploited by an unauthenticated user. It was possible for an attacker to use a vulnerability in the configuration of the XML processor to read any file on the host system. Because all credentials were stored in a cleartext file, it was possible to steal all users' credentials (including the highest privileged users).
