Summary

CVE-2025-71002 is a medium-severity Divide By Zero (CWE-369) vulnerability in Oneflow Oneflow. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 20th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

FPE DoS via crafted input directly matches application exploitation for denial of service.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly blocks the crafted numeric input that triggers the floating-point exception (CWE-369) in flow.column_stack before the divide-by-zero or type-conversion fault occurs.

prevent

Ensures the FPE is caught and handled gracefully rather than terminating the process, converting the crash into a non-fatal error condition.

respond

Requires prompt application of a vendor patch or code fix that eliminates the numeric-handling flaw in the column_stack component.

detects

Security testing in development can detect divide-by-zero conditions before release.

prevents

Secure development lifecycle includes input validation and error-handling practices that can prevent divide-by-zero faults.

prevents

Application security requirements can mandate checks for zero denominators and safe arithmetic handling.

prevents

Secure architecture principles encourage defensive coding patterns that avoid arithmetic exceptions.

prevents

Secure coding standards directly require validation to prevent divide-by-zero and similar runtime faults.
