EUVDB-ID: #VU104137

Risk: Medium

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Exploit availability: No

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.

Mitigation

Install updates from vendor's repository.
