Psftp

Psftp is a modestly scoped file-transfer utility whose vulnerability surface centers on the psftpd server component and reflects the authentication and input-handling demands of network protocol implementation. The recurring weakness classes include externally controlled resource references, improper authentication, input-validation gaps, insufficiently protected credentials, and use-after-free conditions, which collectively span authentication bypass, credential exposure, and memory-safety concerns. Current exploitation activity and exposure counts are shown alongside this summary.
