PRODUCT DESCRIPTION

Opcenter Quality is a quality management system (QMS) that enables organizations to safeguard compliance, optimize quality, reduce defect and rework costs and achieve operational excellence by increasing process stability. The integrated process capabilities (control charts, statistics, quality gates) can detect production errors to avoid further processing and shipment of nonconforming material.

VULNERABILITY CLASSIFICATION

The vulnerability classification has been performed by using the CVSS scoring system in version 3.1 (CVSS v3.1) (https://www.first.org/cvss/). The CVSS environmental score is specific to the customer’s environment and will impact the overall CVSS score. The environmental score should therefore be individually defined by the customer to accomplish final scoring.

An additional classification has been performed using the CWE classification, a community-developed list of common software security weaknesses. This serves as a common language and as a baseline for weakness identification, mitigation, and prevention efforts. A detailed list of CWE classes can be found at: https://cwe.mitre.org/.

Vulnerability CVE-2022-33736

The affected applications do not properly validate login information during authentication. This could lead to denial of service condition for existing users or allow unauthenticated remote attackers to successfully login without credentials.

CVSS v3.1 Base Score	9.6
