Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-56513 is a critical vulnerability in NiceHash QuickMiner version 6.12.0, where the software performs automatic updates over HTTP without validating digital signatures or performing hash checks on downloaded files. This flaw, classified under CWE-494 (Download of Code Without Integrity Check), allows attackers to compromise the update mechanism, enabling the delivery and execution of malicious executables. The issue 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), reflecting its high severity due to the lack of authentication or integrity verification in the update pipeline.
An attacker capable of intercepting or redirecting network traffic to the update URL—such as through man-in-the-middle attacks on unsecured networks—can hijack the process and substitute legitimate updates with arbitrary executables. These malicious files are automatically executed by the miner software without user interaction, resulting in full remote code execution on the victim's system. No privileges or physical access are required, making it exploitable by remote adversaries over the network with low complexity.
References to the vulnerability include detailed analyses in Medium posts by researcher @princep49036142, which describe the auto-update pipeline's insecurity but do not specify official patches or vendor advisories at the time of publication on 2025-09-30.

Mitigating Controls (NIST 800-53 r5) AI
Requires digital signature verification before component installation, directly stopping execution of code downloaded without integrity checks.
Employs integrity verification tools that can identify missing or failed checks on downloaded software after the fact.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Directly requires assessing authenticity/integrity of software before acquisition and use, preventing unverified downloads.
Requires cryptographic integrity protections (signatures/hashes) for data-in-transit, covering downloaded code.
Prevents execution of unauthorized software, blocking the outcome of an unchecked download.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Mandating integrity checks, digital signatures, and origin tracing for ICT components directly reduces the chance that code or firmware lacking an integrity check will be accepted into the organisation’s environment.
Requiring suppliers to disclose vulnerabilities and mandating verified updates lowers the chance that code lacking integrity checks will be deployed.
