CVE-2017-15271

33
FAUCET Score

CVE-2017-15271 describes a remotely triggerable use-after-free vulnerability in the SFTP component of PSFTPd 10.0.4 Build 729, affecting psftp and psftpd products. This flaw, rated Medium severity (CVSS 5.9), allows unauthenticated attackers to cause a denial-of-service by sending a crafted SSH identification string, leading to a NULL pointer dereference and subsequent use-after-free during connection cleanup. While not actively exploited in the wild and lacking Metasploit or Nuclei modules, an ExploitDB entry (EDB-43144) confirms exploitability, though there is minimal community discussion or media coverage.
