Winscp

WinSCP is a widely deployed file-transfer client that handles SSH and SFTP operations across diverse enterprise and individual user environments, presenting a notable attack surface due to its direct exposure to user input and file-system operations. Vulnerabilities affecting the vendor skew toward serious outcomes, frequently acquire public exploit code, and recur through weakness classes including improper input validation, buffer overflows, path traversal, and argument injection—issues characteristic of applications that parse remote protocols and construct file paths or system commands. Defenders should treat WinSCP advisories as high-priority given the client's role in privileged file access and the availability of weaponizable exploits; live severity, exploitation, and exposure counts are shown alongside this summary.
