Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.
Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.
Directly implements checks on information inputs to reject invalid data before processing.
Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Remote unauthenticated input validation flaw in exposed OneFlow component directly enables T1190 for initial access and T1499.004 for application-layer DoS via crafted input.
NVD Description
An input validation vulnerability in the flow.arange() component of OneFlow v0.9.0 allows attackers to cause a Denial of Service (DoS) via a crafted input.
