CVE-2020-7588
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been identified in Opcenter Execution Discrete (All versions < V3.2), Opcenter Execution Foundation (All versions < V3.2), Opcenter Execution Process (All versions < V3.2), Opcenter Intelligence (All versions < V3.3), Opcenter Quality (All versions < V11.3), Opcenter RD&L (V8.0), SIMATIC IT LMS (All versions < V2.6), SIMATIC IT Production Suite (All versions < V8.0), SIMATIC Notifier Server for Windows (All versions), SIMATIC PCS neo (All versions < V3.0 SP1), SIMATIC STEP 7 (TIA Portal) V15 (All versions < V15.1 Update 5), SIMATIC STEP 7 (TIA Portal) V16 (All versions < V16 Update 2), SIMOCODE ES V15.1 (All versions < V15.1 Update 4), SIMOCODE ES V16 (All versions < V16 Update 1), Soft Starter ES V15.1 (All versions < V15.1 Update 3), Soft Starter ES V16 (All versions < V16 Update 1). Sending a specially crafted packet to the affected service could cause a partial remote denial-of-service, that would cause the service to restart itself.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA remote denial-of-service vulnerability exists in multiple Siemens industrial software products (Opcenter, SIMATIC IT, SIMATIC PCS neo, SIMATIC STEP 7/TIA Portal, SIMOCODE ES, Soft Starter ES). An unauthenticated remote attacker can send specially crafted packets to the affected service, causing it to restart unexpectedly.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Siemens industrial softwareReview installed programs on the system or check the Siemens Software Lifecycle Management database for installed Siemens industrial software products such as Opcenter Execution, Opcenter Intelligence, Opcenter Quality, SIMATIC IT LMS, or SIMATIC IT Production Suite.Affected if Any of the affected products listed in the CVE are installed.
-
Determine installed version of Opcenter productsOpen the Siemens Opcenter application or check the installed programs list, and locate the version number for Opcenter Execution Discrete, Opcenter Execution Foundation, Opcenter Execution Process, Opcenter Quality, or Opcenter Intelligence.Affected if For Opcenter Execution Discrete/Foundation/Process: version is below 3.2. For Opcenter Quality: version is below 11.3. For Opcenter Intelligence: any version found (all versions affected).
-
Determine installed version of SIMATIC IT productsCheck the installed programs list or SIMATIC IT application properties for SIMATIC IT LMS or SIMATIC IT Production Suite version numbers.Affected if Any version of SIMATIC IT LMS or SIMATIC IT Production Suite is installed (all versions affected).
-
Check network exposure of affected servicesReview firewall rules and network configuration to determine if the Siemens industrial software services are exposed to untrusted networks or the internet.Affected if The affected service is reachable from untrusted network segments (the vulnerability is remotely exploitable via network packets).
The environment is affected if any Siemens industrial software product from the CVE list is installed with a version matching the affected ranges AND the service is network-accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data3.211.3
Apply the vendor-supplied updates: upgrade to Opcenter Execution Discrete/Foundation/Process V3.2 or later, Opcenter Intelligence V3.3 or later, Opcenter Quality V11.3 or later, SIMATIC IT LMS V2.6 or later, SIMATIC IT Production Suite V8.0 or later, SIMATIC PCS neo V3.0 SP1 or later, SIMATIC STEP 7 V15.1 Update 5 or later, SIMATIC STEP 7 V16 Update 2 or later, and corresponding updates for SIMOCODE ES and Soft Starter ES. Additionally, network segmentation and firewall rules should limit exposure of affected services to trusted networks.
