Inefficient algorithmic complexity in IBM InfoSphere Information Server

1) Inefficient Algorithmic Complexity

EUVDB-ID: #VU72750

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-25881

CWE-ID: CWE-407 - Inefficient Algorithmic Complexity

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to regular expression denial of service that occurs when the server reads the cache policy from the request using this library. A remote unauthenticated attacker can send malicious request header values to the server and perform a denial of service attack.

Mitigation

Install update from vendor's website.
