CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HSummary
CVE-2025-2531 is a high-severity Heap-based Buffer Overflow (CWE-122) vulnerability in Luxion Keyshot. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 14th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-2531 is a heap-based buffer overflow vulnerability in Luxion KeyShot that occurs during parsing of DAE files. The flaw stems from insufficient validation of the length of user-supplied data before it is copied into a heap buffer, enabling remote code execution. It affects installations of Luxion KeyShot and carries a CVSS score of 7.8.
An unauthenticated attacker can exploit the issue by convincing a target to open a malicious DAE file or visit a malicious page. Successful exploitation grants arbitrary code execution in the context of the current process.
The Zero Day Initiative advisory ZDI-25-174, originally tracked as ZDI-CAN-23704, describes the vulnerability and is the primary source of public details.
EPSS for the CVE rose from a low baseline to a recorded peak of 0.0125, indicating a measurable increase in exploitation interest after disclosure.

visit a malicious page or open a malicious file. The specific flaw exists within the parsing of dae files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-23704.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (including fuzzing and memory-error detectors) can discover heap overflows after they have been coded.
Input validation enforces bounds checking on data written to heap buffers, directly stopping the overflow condition from being introduced.
Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.
Security engineering principles require use of memory-safe constructs and bounds-checked allocation routines that avoid introducing heap overflows.
Memory-protection mechanisms limit the ability of a heap overflow to execute attacker-controlled code or corrupt adjacent structures.

Secure-development practices directly require bounds checking and safe memory handling that prevent heap overflows.
Vulnerability scanning and recording can discover heap-overflow flaws but does not prevent their introduction in code.
Timely patching removes known heap-overflow instances after they exist.

Security testing in development and acceptance can detect heap overflows before release.
Secure development lifecycle mandates practices that reduce the likelihood of introducing heap overflows.
Application security requirements can specify bounds-checking and safe memory APIs that mitigate heap overflows.
Secure architecture and engineering principles include memory-safety and input-validation controls that address heap overflows.
Secure coding standards directly prescribe techniques (safe functions, bounds checks) that prevent heap-based buffer overflows.
Change management can enforce review gates that catch unsafe memory operations before deployment.
