FKIE_CVE-2010-20034

Vulnerability from fkie_nvd - Published: 2025-08-21 21:15 - Updated: 2026-06-16 23:19
Severity
8.5 (High) - CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
Gekko Manager FTP Client <= 0.77 contains a stack-based buffer overflow in its FTP directory listing parser. When processing a server response to a LIST command, the client fails to properly validate the length of filenames. A crafted response containing an overly long filename can overwrite the Structured Exception Handler (SEH), potentially allowing remote code execution.
