CVE-2008-6899

Status: ModifiedHigh (9)—💥 Exploit

Multiple buffer overflows in freeSSHd 1.2.1 allow remote authenticated users to cause a denial of service (crash) and execute arbitrary code via a long (1) open, (2) unlink, (3) mkdir, (4) rmdir, or (5) stat SFTP command.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:S/C:C/I:C/A:C
Base score: 9

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 5.29%
Percentile among all scored CVEs: 92
Score date: 10/7/2026

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.
