EUVDB-ID: #VU50095

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2020-13562

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via the "action" parameter in admin/acl_admin.php.
