Is CVE-2010-1297 (Adobe Flash Player Memory Corruption) being exploited in the wild?

By NHI Mgmt Group Editorial Team Updated October 19, 2026 Domain: Threats, Abuse & Incident Response

Yes. CISA added CVE-2010-1297 to its Known Exploited Vulnerabilities catalogue on 8 June 2022, which it does only when there is reliable evidence of active exploitation. CISA has not linked it to known ransomware campaigns. Adobe Flash Player contains a memory corruption vulnerability that allows remote attackers to execute code or cause denial-of-service (DoS). Any organisation running the affected product should treat remediation as urgent.

What “exploited in the wild” means for this CVE

For a KEV-listed flaw like this one, the practical question is not whether exploitation is theoretically possible, but whether defenders should assume real attacker activity and move from normal patch timing to emergency response. That changes prioritisation, because a memory corruption flaw in a widely deployed client product can become a reliable entry point for code execution or disruption.

When you are validating exposure, treat the vendor advisory, asset inventory, and the current KEV record as the authoritative triad. If the product is present on any endpoint, browser, or legacy application path, it belongs on the urgent remediation list even if you have not seen an incident yet.

Why active exploitation changes the response path

Active exploitation shifts the issue from “security debt” to “known attack surface.” In practice, that means the first decision is scope, not root cause: find every system where the vulnerable product can still run, including unmanaged desktops, virtual desktops, kiosk systems, and older software stacks that may have been missed by routine scanning.

For triage and prioritisation, pair the KEV status with exploitability and business exposure. NIST National Vulnerability Database is useful for the baseline vulnerability record, while CISA Known Exploited Vulnerabilities Catalog is the operational signal that matters most when deciding what must be remediated first.

What to do if you cannot patch immediately

When patching is delayed, the goal is to reduce the number of places the vulnerable component can be reached and to narrow the blast radius if exploitation succeeds. That usually means removing unnecessary exposure, disabling the vulnerable function where possible, and isolating the affected systems from high-value assets and sensitive workflows.

Legacy client software often survives because it is tied to a business process rather than because it is technically required. In those cases, temporary compensating controls should be treated as short-lived risk reduction, not as a substitute for removal. FIRST EPSS can help you support prioritisation when several vulnerabilities are competing for attention, but a KEV-listed item should still outrank ordinary backlog work.

Standards & Framework Alignment

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.

CIS Controls v8, NIST SP 800-53 Rev 5 and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.

Framework	Control / Reference	Relevance
CIS Controls v8	CIS-7 — Continuous Vulnerability Management	Active exploitation and urgent remediation are core vulnerability-management concerns.
Recommendation — Prioritise KEV-listed flaws for immediate remediation and exception tracking.
NIST SP 800-53 Rev 5	RA-5 — Vulnerability Monitoring and Scanning	The question centers on confirming exposure and handling a known exploited vulnerability.
	SI-2 — Flaw Remediation	A KEV-listed memory corruption flaw requires rapid flaw remediation or mitigation.
Recommendation — Scan assets for the vulnerable product and verify remediation status quickly. Apply the vendor fix or compensating mitigation as soon as exposure is confirmed.
NIST CSF 2.0	GV.RM-01 — Risk Management Strategy	KEV status changes prioritisation and exception handling within risk strategy.
	PR.DS-01 — Data-at-Rest	If exploitation can lead to compromise, protecting exposed assets and reducing blast radius matters.
Recommendation — Escalate KEV-listed vulnerabilities into your highest-priority remediation workflow. Reduce exposure of affected systems until remediation is complete.

Practitioner Guidance

What to prioritise: Confirm where Adobe Flash Player still exists, then separate internet-facing or user-exposed systems from isolated or decommissioned ones. The exposed population should drive your order of operations, not the age of the CVE.

What to verify: Check whether the vulnerable component is actually executable on the endpoint or embedded in a dependency path, and verify that removal or mitigation is complete across the fleet. A partial cleanup often leaves a small number of high-risk exceptions behind.

Decision rule: If a KEV-listed vulnerability is present on an active system, treat remediation as urgent even when you have no evidence of compromise. If remediation must wait, document the exception, narrow exposure, and schedule targeted follow-up validation rather than relying on passive monitoring alone.

Practitioner takeaway: For exploited-in-the-wild CVEs, the decisive question is not whether the flaw is interesting, but whether any live system still gives an attacker a reachable path to it.
