Unauthenticated file write via upload path traversal
Published Oct 22, 2025 · Updated Oct 22, 2025
Path traversal in Hikvision CSMP iSecure Center through 2023-06-25 allows remote attackers to upload files outside the intended directory. The /center/api/files upload handler fails to neutralize traversal sequences in a supplied file path, so it writes attacker-controlled content beyond its designated directory. No authentication or user interaction is required; the arbitrary file write can alter server-hosted data, and public records report exploitation during 2024 and 2025.
