Mark‑of‑the‑Web Bypass in 7‑Zip (CVE‑2025‑0411) Enables Remote Code Execution
What It Is – 7‑Zip’s “Mark‑of‑the‑Web” (MOTW) protection can be bypassed, allowing a remote attacker to execute arbitrary code under the current user’s context.
Exploitability – The vulnerability is remotely exploitable; proof‑of‑concept code is publicly available. CVSS v3.1 scores 7.8 (High).
Affected Products – 7‑Zip 23.01 and earlier releases for Windows.
Why It Matters for Trust & Control Assurance
- Demonstrates the need for continuous software‑integrity monitoring and timely patch management as evidence of due‑diligence.
- A successful bypass undermines execution‑control safeguards, eroding the audit trail that regulators and enterprise buyers demand.
- Organizations that can prove systematic remediation of such flaws signal a robust control‑assurance posture across multiple frameworks (e.g., NIST CSF, ISO 27001).
Recommended Actions – Verify your 7‑Zip version, apply the vendor‑released patch immediately, update your asset inventory, and capture remediation evidence in your control‑mapping repository. Source: [CISA KEV – CVE‑2025‑0411]
