Multiple vulnerabilities in IBM Db2 Web Query for i

1) Input validation error

EUVDB-ID: #VU75561

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-20860

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to an input validation error caused by using the wildcard ("**") as a pattern in Spring Security configuration with the mvcRequestMatcher, which creates a mismatch in pattern matching between Spring Security and Spring MVC. A remote attacker can bypass certain security restrictions.
