CVE-2024-53320
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 · uneditedQualisys C++ SDK commit a32a21a was discovered to contain multiple stack buffer overflows via the GetCurrentFrame, SaveCapture, and LoadProject functions.
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 confidenceStack buffer overflows in the Qualisys C++ SDK's GetCurrentFrame, SaveCapture, and LoadProject functions allow attackers to overwrite stack memory by providing input larger than allocated buffer sizes, potentially enabling arbitrary code execution or denial of service.

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 Qualisys C++ SDK installationSearch for Qualisys SDK files (e.g., QTM, qualisys, libqualisys) in common installation directories like C:\Program Files\Qualisys or /usr/local/Qualisys, or check for linked libraries in your application (e.g., libqualisys.so, QualisysSDK.lib)Affected if The Qualisys C++ SDK is present in the environment
-
Identify installed SDK versionCheck version metadata in SDK binaries, headers, or accompanying VERSIONINFO resources; look for version.h, VERSION, or similar files in the SDK installation directoryAffected if The version number is below the fixed release that addresses CVE-2024-53320 (contact Qualisys for specific version numbers)
-
Determine if vulnerable functions are calledReview application source code or binary for calls to GetCurrentFrame, SaveCapture, or LoadProject functions from the Qualisys SDKAffected if The application directly invokes any of these three functions with external or file-based input
-
Check input source to affected functionsAudit code paths that feed data into GetCurrentFrame, SaveCapture, and LoadProject to identify if untrusted input (network data, capture files, project files) reaches these functions without size validationAffected if External or file-based input is passed to these functions without bounds checking on buffer sizes
-
Inspect runtime buffer allocationsIf source code is unavailable, use runtime debugging tools or memory analyzers to observe if stack buffers allocated by these functions receive input exceeding their declared sizes during executionAffected if Stack buffers are overwritten with data larger than their allocated size during normal or test operations
Your environment is affected if the Qualisys C++ SDK is installed, the version predates the patched release, and your application calls GetCurrentFrame, SaveCapture, or LoadProject with unvalidated input that could overflow stack buffers.

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 dataUpdate or patch the Qualisys C++ SDK to a version that addresses these buffer overflow vulnerabilities, and implement proper input validation and bounds checking in the affected functions.
