How do I mitigate CVE-2014-0497 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.

Is CVE-2014-0497 actively exploited in the wild?

Yes. There are 3 known exploit references for CVE-2014-0497, including 1 documented proof-of-concept exploit on Exploit-DB and 2 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2014-0497?

CVE-2014-0497 has an EPSS (Exploit Prediction Scoring System) score of 99.9%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2014-0497 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2014-0497 (Adobe Flash Player Integer Underflow Vulnerablity) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2024-09-17. CISA required all US federal civilian agencies to remediate this vulnerability by 2024-10-08. The required action was: The impacted product is end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue utilization of the product. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.
