CVE-2022-34273
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 PADS Standard/Plus Viewer (All versions). The affected application contains an out of bounds write past the end of an allocated structure while parsing specially crafted PCB files. This could allow an attacker to execute code in the context of the current process. (FG-VD-22-038)
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 confidencePADS Standard/Plus Viewer contains an out-of-bounds write vulnerability in its PCB file parsing logic. When parsing specially crafted PCB files, the application writes past the end of an allocated memory structure, leading to memory corruption that can be leveraged for arbitrary code execution in the context of the current process.

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.
-
Verify PADS Viewer installationCheck for PADS Viewer executable on the system. Common installation paths include: C:\Program Files\Siemens\PADS\, C:\Program Files (x86)\Siemens\PADS\, or search for 'PADS_Viewer.exe' / 'padspv.exe' in Program Files directories.Affected if PADS Viewer executable is found on the system
-
Confirm installed versionRight-click the PADS Viewer executable, select Properties, then view the Details tab for version information. Alternatively, run 'dir' or PowerShell 'Get-ChildItem' to list files with version data in the installation directory.Affected if Any version of PADS Viewer is installed (all versions are affected)
-
Identify PCB file parsing capabilityVerify the application can open PCB file types. Look for .pcb, .asc, or other PCB-related file extensions associated with PADS in the file association or within the application's Open dialog.Affected if The viewer can open PCB files from the file system (parsing is enabled by default)
-
Check for untrusted file handlingAttempt to locate or document any PCB files from external or untrusted sources that could be opened by the viewer. Check browser download folders, email attachments, or network shares for .pcb files.Affected if The user can open PCB files from untrusted sources through the viewer
If PADS Viewer is installed and can parse PCB files, the environment is affected by this vulnerability since all versions are impacted by the out-of-bounds write flaw.

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 dataApply vendor patch when available; until then, restrict opening of untrusted PCB files and consider running the viewer in an isolated environment to limit impact of potential exploitation.
