Senserva AI Opinion for CVE-2018-5002

Adobe Flash Player's stack-based buffer overflow was exploited as a zero-day via crafted Office documents carrying embedded Flash content, a delivery trick that bypassed browser protections entirely. Flash reached end of life in 2020, so any copy still installed is permanently vulnerable to this High Severity (CVSS 7.8) KEV-listed flaw and everything found after it. The 25 percent EPSS score persists because old payloads still circulate.

Do this: Search endpoints for lingering Flash Player installations and remove them outright rather than attempting to patch.
