Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-47813 is an information disclosure vulnerability (CWE-209) affecting the loginok.html component in Wing FTP Server versions prior to 7.4.4. When a long value is supplied in the UID cookie, the application exposes its full local installation path. Published on 2025-07-10, the vulnerability carries a CVSS v3.1 base score of 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N), indicating moderate severity primarily due to limited confidentiality impact.
An authenticated attacker with low privileges (PR:L) can exploit this over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). By sending a specially crafted request to loginok.html containing an excessively long UID cookie value, the attacker retrieves the server's complete installation path, enabling reconnaissance that could facilitate further attacks such as path traversal or privilege escalation when chained with other flaws.
Mitigation involves upgrading to Wing FTP Server 7.4.4 or later, as indicated by the affected version range in the CVE description. Vendor guidance is available at wftpserver.com, with additional details in advisories like the GitHub entry from MrTuxracer.
This CVE appears in the CISA Known Exploited Vulnerabilities Catalog and relates to other Wing FTP Server issues, including CVE-2025-47812 (an RCE), as covered by RCEsecurity.

Secure coding standards explicitly forbid exposing sensitive data in errors.
Security testing can detect error messages that leak sensitive information.
Logging policy can require suppression of sensitive data in error messages.
Secure SDLC mandates error-handling rules that avoid leaking sensitive information.
Application security requirements can specify safe error messaging.
Secure architecture principles include proper exception handling.
