Cross‑Site Scripting (XSS) in Adobe Flash Player (CVE‑2012‑0767) Enables Remote Script Injection
What It Is – Adobe Flash Player contains a cross‑site scripting flaw that lets a remote attacker inject arbitrary web script or HTML into the context of the vulnerable Flash runtime.
Exploitability – The vulnerability is publicly disclosed (CVE‑2012‑0767) and has been observed in the wild; no authentication is required. CVSS v3.1 base score 6.1 (Medium).
Affected Products – Adobe Flash Player (all versions prior to the vendor‑issued patch).
Why It Matters for Trust & Control Assurance
- Demonstrates the need for continuous third‑party component monitoring and evidence that vulnerable versions are identified and remediated.
- Provides audit‑ready proof that patch management and secure configuration controls are operating as intended.
- Supports a defensible posture for frameworks such as NIST CSF 2.0, where “Secure Development and Configuration Management” is a core control objective.
Recommended Actions
- Inventory all endpoints and web applications that still host Adobe Flash Player.
- Verify the installed Flash version against the vendor’s advisory; apply the patch or disable Flash where possible.
- Capture remediation evidence (e.g., patch logs, configuration snapshots) to satisfy control‑mapping requirements.
- Update your secure‑development lifecycle policies to include regular review of third‑party runtime components.
