PRODUCT DESCRIPTION

PLM Help Server is a documentation server used for hosting the Help or Manuals files.

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-2022-44575

A reflected cross-site scripting (XSS) vulnerability exists in the web interface of the affected application that could allow an attacker to execute malicious javascript code by tricking users into accessing a malicious link.
