CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-20741 is a high-severity Write-what-where Condition (CWE-123) vulnerability in Adobe Substance 3D Painter. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked at the 18th 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-16 (Memory Protection) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (including fuzzing and bounds checks) finds out-of-bounds write flaws before deployment.
Memory-protection mechanisms block unauthorized writes to arbitrary locations even if a write-what-where primitive exists.
Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.
Secure engineering principles require memory-safe coding and bounds checking that eliminate the root cause of write-what-where flaws.
Process isolation confines the blast radius of an arbitrary write so it cannot affect other domains.
Input validation directly stops malformed data from triggering buffer overflows that produce arbitrary write-what-where conditions.

Vulnerability scanning and recording can discover out-of-bounds write flaws so they can be remediated.
Patching or replacing vulnerable software directly eliminates known instances of this coding weakness.
Secure SDLC practices directly prevent arbitrary write conditions via safe coding, bounds checking, and memory-safe constructs.
