FKIE_CVE-2026-46746
Vulnerability from fkie_nvd - Published: 2026-06-09 10:16 - Updated: 2026-07-23 08:10
Severity
Summary
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 6). The application does not properly sanitize user input in the /api/sftp/uploadFiles endpoint, allowing the injection of shell command payloads via crafted directory names. These payloads are stored and executed when directory listings are retrieved. This could allow an authenticated remote attacker to execute arbitrary commands on the underlying operating system with the privileges of the affected service user (sinecins).
