CVE-2020-15827
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 · uneditedIn JetBrains ToolBox version 1.17 before 1.17.6856, the set of signature verifications omitted the jetbrains-toolbox.exe file.
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 confidenceJetBrains ToolBox version 1.17 before 1.17.6856 omitted the jetbrains-toolbox.exe file from its digital signature verification process, allowing potential replacement with a malicious executable without detection. This signature bypass could enable code execution in the context of the trusted application.

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.
-
Locate the JetBrains Toolbox executableFind the jetbrains-toolbox.exe file on the system. On Windows, common locations include %LOCALAPPDATA%\JetBrains\Toolbox\bin\ or the installation directory where the application was originally installed.Affected if The executable cannot be found or is located in an unexpected directory.
-
Check the installed JetBrains Toolbox versionRight-click on jetbrains-toolbox.exe, select Properties, and view the File Version or Product Version field. Alternatively, open JetBrains Toolbox, click the user icon (top left), and view the version displayed in the Settings or About section.Affected if The installed version is 1.17.0.0 through 1.17.6855, or shows version 1.17 with build number less than 6856.
-
Compare version against vulnerable rangeVerify if the installed version falls within >= 1.17 and < 1.17.6856. Note that versions 1.17.6856 and later contain the fix.Affected if The version is 1.17.x where x is less than 6856, placing it in the vulnerable range.
-
Verify digital signature on the executableRight-click jetbrains-toolbox.exe, select Properties, go to the Digital Signatures tab, and verify that the executable has a valid signature from JetBrains s.r.o. Ensure the signature covers the main executable and is not missing from the verification chain.Affected if The executable lacks a valid digital signature, or signature verification is omitted/not applied to this file.
If the installed JetBrains Toolbox version is 1.17.x with build number below 6856, the environment is affected by this signature verification bypass vulnerability.
