CVE-2007-4324

Status: ModifiedMedium (5)—
ActionScript 3 (AS3) in Adobe Flash Player 9.0.47.0, and other versions and other 9.0.124.0 and earlier versions, allows remote attackers to bypass the Security Sandbox Model, obtain sensitive information, and port scan arbitrary hosts via a Flash (SWF) movie that specifies a connection to make, then uses timing discrepancies from the SecurityErrorEvent error to determine whether a port is open or not. NOTE: 9.0.115.0 introduces support for a workaround, but does not fix the vulnerability.
CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
Base score: 5
Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 7.93%
Percentile among all scored CVEs: 95
Score date: 10/8/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
