CVE-2024-53320
Published: 31 January 2025
Summary
CVE-2024-53320 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 33.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2024-53320 is a critical vulnerability in the Qualisys C++ SDK at commit a32a21a, involving multiple stack buffer overflows triggered via the GetCurrentFrame, SaveCapture, and LoadProject functions. Classified under CWE-120, it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), highlighting its severe potential impact.
The vulnerability enables remote exploitation over the network with low complexity, requiring no privileges or user interaction. Attackers can achieve high impacts on confidentiality, integrity, and availability, potentially leading to arbitrary code execution or system crashes on affected systems integrating the vulnerable SDK.
Mitigation details are documented in the GitHub issue at https://github.com/qualisys/qualisys_cpp_sdk/issues/47. Security practitioners should review this reference for patches or workarounds specific to the SDK.

SI-2 requires identifying, reporting, and correcting system flaws like this stack buffer overflow, directly enabling patching to the fixed SDK commit or applying documented workarounds.
SI-16 implements memory protections such as stack canaries, ASLR, and DEP that directly mitigate stack buffer overflow exploitation leading to arbitrary code execution.
SI-10 enforces validation of inputs to vulnerable SDK functions like GetCurrentFrame, SaveCapture, and LoadProject to prevent malformed data from triggering overflows.
