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 · unedited
A vulnerability has been identified in LOGO! Soft Comfort (All versions < V8.3). The vulnerability could allow an attacker to execute arbitrary code if the attacker tricks a legitimate user to open a manipulated project. In order to exploit the vulnerability, a valid user must open a manipulated project file. No further privileges are required on the target system. The vulnerability could compromise the confidentiality, integrity and availability of the engineering station. At the time of advisory publication no public exploitation of this security vulnerability was known.

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 confidence

A code execution vulnerability exists in LOGO! Soft Comfort versions prior to V8.3. The flaw is triggered when a user opens a specially crafted manipulated project file, likely due to insufficient input validation during project file parsing. This allows an attacker to execute arbitrary code on the victim's engineering station with the same privileges as the legitimate user.

MitigationUpgrade LOGO! Soft Comfort to version 8.3 or later. Until upgraded, exercise extreme caution with project files from untrusted sources and implement additional endpoint protection controls.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check if LOGO! Soft Comfort is installed
    Look for the software in standard installation directories such as C:\Program Files\Siemens\LOGO! Soft Comfort or check Windows Programs and Features (Add/Remove Programs) for an entry named 'LOGO! Soft Comfort'
    Affected if LOGO! Soft Comfort appears in installed programs
  2. Determine the installed version
    Right-click on the LOGO! Soft Comfort executable (typically named LogoSoftComfort.exe) in the installation folder, select Properties, then go to the Details tab to view the File Version
    Affected if The displayed File Version is lower than 8.3.0 or the product version shows a number less than 8.3
  3. Check program version through installed programs list
    In Windows Control Panel > Programs and Features, locate 'LOGO! Soft Comfort' and check the Version column in the program entry
    Affected if The version shown is blank or shows a version number less than 8.3
  4. Identify associated project file types
    Check for .lsc or .logo file extensions on the system, which are the project file formats used by LOGO! Soft Comfort. These files are typically stored in user documents or project folders
    Affected if Project files with .lsc or .logo extensions exist and the software version is confirmed as less than 8.3

The environment is affected if LOGO! Soft Comfort is installed with any version prior to 8.3, as opening a specially crafted .lsc or .logo project file could allow arbitrary code execution.
