CVE-2019-18994
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 · uneditedDue to a lack of file length check, the HMIStudio component of ABB PB610 Panel Builder 600 versions 2.8.0.424 and earlier crashes when trying to load an empty *.JPR application file. An attacker with access to the file system might be able to cause application malfunction such as denial of service.
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 · moderate confidenceA file validation vulnerability exists in HMIStudio component of ABB PB610 Panel Builder 600. When loading an empty *.JPR application file, the lack of file length validation causes the application to crash. An attacker with file system access can exploit this by placing an empty JPR file to trigger a denial of service condition.

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.
-
Check if ABB PB610 Panel Builder 600 is installedSearch for the product in your system using your operating system's program list or by searching for 'Panel Builder 600' or 'ABB' in your installed applicationsAffected if The product is found on the system
-
Determine the installed version of ABB PB610 Panel Builder 600Right-click on the application executable or access the program's About/Help section to view version information, then compare it to the affected range: version 2.8.0.424 or lowerAffected if The installed version is 2.8.0.424 or any version lower than 2.8.0.424
-
Locate JPR application files on the systemSearch your file system for files with the .JPR extension, particularly in project directories or application data folders related to ABB Panel Builder 600Affected if JPR files are present on the system and could be accessed by unauthorized users
-
Check for application crash reports or logsExamine Windows Event Viewer for application crash events, or check for crash dump files in the application directory or user documents foldersAffected if Recent crash events related to HMIStudio or Panel Builder 600 are logged after loading JPR files
-
Verify file system access controls on JPR file locationsReview file permissions on directories containing JPR files to determine if untrusted users could place files in those locationsAffected if Users without proper authorization can write to directories where JPR files are stored
You are affected if ABB PB610 Panel Builder 600 version 2.8.0.424 or lower is installed and JPR files exist in accessible locations on your system.
