Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Security features bypass

EUVDB-ID: #VU62314

Risk: Medium

CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2022-22968

CWE-ID: CWE-254 - Security Features

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to patterns for disallowedFields on a DataBinder are case sensitive, which means a field is not effectively protected unless it is listed with both upper and lower case for the first character of the field, including upper and lower case for the first character of all nested fields within the property path. A remote attacker can bypass implemented security restrictions by passing case sensitive data to the application.

Mitigation

Install update from vendor's website.
