Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in application's database.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can send a specially crafted email to the affected server and execute arbitrary SQL commands within the application's database.

Note, the vulnerability exists only when the build time option _USE_SQLITE_ was set (it enables the use of SQLite for the hints databases), runtime config enables ETRN and enforces ETRN serialization.
