CVE-2008-2573

CVE-2008-2573 describes a stack-based buffer overflow vulnerability in the SFTP component of freeSSHd version 1.2.1. This flaw allows remote, authenticated attackers to execute arbitrary code by supplying an excessively long directory name within an SSH_FXP_OPENDIR command. With a CVSS score of 8.5, it is considered highly severe due to its network attack vector, medium attack complexity, and complete compromise of confidentiality, integrity, and availability. While not listed on CISA's KEV catalog, exploit code demonstrating proof-of-concept and SEH-based exploitation is publicly available on ExploitDB, though there is no evidence of active exploitation or significant community discussion.
