CVE-2009-1437

Status: ModifiedHigh (9.3)—💥 Exploit

Stack-based buffer overflow in PortableApps CoolPlayer Portable (aka CoolPlayer+ Portable) 2.19.6 and earlier allows remote attackers to execute arbitrary code via a long string in a malformed playlist (.m3u) file. NOTE: this may overlap CVE-2008-3408.

CVSS

Version: 2.0
Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
Base score: 9.3

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 14%
Percentile among all scored CVEs: 96
Score date: 10/10/2026

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).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
