CVE-2003-1339

Status: ModifiedHigh (10)—💥 Exploit

Stack-based buffer overflow in eZnet.exe, as used in eZ (a) eZphotoshare, (b) eZmeeting, (c) eZnetwork, and (d) eZshare allows remote attackers to cause a denial of service (crash) or execute arbitrary code, as demonstrated via (1) a long GET request and (2) a long operation or autologin parameter to SwEzModule.dll.

CVSS

Exploitation probability (EPSS)

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.
