Processing Procedure

How We Handle Vulnerability Reports

Handling Vulnerability Reports

Upon receiving a vulnerability report, our PSIRT follows a structured process.
01

Receipt and Confirmation

We will confirm receipt of your report within one week. If we need additional information, we will contact you.

02

Initial Evaluation

Our PSIRT determines whether the report falls within our jurisdiction and whether a potential vulnerability exists.

In doing so, we take the following into account in particular:

  • Affected Products and Versions
  • possible effects
  • Exploitability and Required Access Rights
  • Relevance for Customers and Operators
03

Analysis and Reproduction

To the extent possible, we attempt to technically understand and reproduce the reported vulnerability. Internal development teams and other relevant departments may be involved in this process.

04

Risk Assessment

Confirmed vulnerabilities are assessed according to established criteria. Among other methods, the Common Vulnerability Scoring System (CVSS) may be used for this purpose. The final assessment may differ from the reporter's initial assessment.

05

Action Plan

Depending on the identified risk and the product architecture, we determine appropriate measures. These may include, for example:

  • Software or Firmware Updates
  • Configuration changes or workarounds
  • Technical Recommendations
  • Documentation or Product Information
06

Feedback

If you have provided us with your contact information, we will notify you of the results of our evaluation.

07

Coordinated Disclosure

We work with whistleblowers based on the principle of coordinated disclosure. The goal is to protect affected customers and operators while ensuring transparent communication.

We ask that you refrain from disclosing information about the vulnerability until the assessment is complete and, if necessary, appropriate measures or customer information are available.

08

Publication

If necessary, a CVE identifier can be requested for a confirmed vulnerability. Depending on the assessment and potential impact, the vulnerability may be classified as Safety Notice be published on our website.
