CVE-2021-3285
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 · uneditedjxbrowser in TI Code Composer Studio IDE 8.x through 10.x before 10.1.1 does not verify X.509 certificates for HTTPS.
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 confidenceThe JxBrowser component embedded in TI Code Composer Studio IDE versions 8.x through 10.x before 10.1.1 fails to validate X.509 certificates during HTTPS connections, allowing man-in-the-middle attackers to intercept or modify encrypted traffic by presenting invalid or malicious certificates.

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 TI Code Composer Studio is installedCheck for the product installation directory (commonly at C:\ti\ccs on Windows or /ti/ccs on Linux) or search for 'Code Composer Studio' in installed programs.Affected if TI Code Composer Studio is not installed on the system
-
Locate the version fileNavigate to the CCS installation directory and locate the version information file. On Windows, this is typically in the product directory under the 'eclipse' subfolder as 'about.ini' or 'product.ini', or check the top-level 'ccs_info.txt' file. On Linux, check the 'ccs_info.txt' in the installation root or the 'About' dialog from the Help menu within the IDE.Affected if Cannot locate version information - TI Code Composer Studio may not be properly installed
-
Extract the installed version numberOpen the version file and read the product version (for example, look for lines containing 'product.version' or read the version number from 'ccs_info.txt'). Note the full version string (such as 8.3.0, 9.3.0, or 10.1.0).Affected if Version number cannot be determined from the installation
-
Compare version against the affected rangeCompare the extracted version to the affected range: versions 8.0.0 through 10.1.0 are vulnerable. The affected condition is: version >= 8.0.0 AND version < 10.1.1.Affected if The installed version is 8.0.0 or higher but lower than 10.1.1 (for example, 8.3.0, 9.1.0, or 10.1.0 would all be affected)
A system is affected only if TI Code Composer Studio version 8.0.0 or higher but lower than 10.1.1 is installed and the JxBrowser component is used for HTTPS connections.

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 data10.1.1
Upgrade TI Code Composer Studio to version 10.1.1 or later, which includes the patched JxBrowser component with proper certificate validation.
