CVE-2010-20034
Gekko Manager FTP Client <= 0.77 contains a stack-based buffer overflow in its FTP directory listing parser.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.58%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
