Username enumeration via distinguishable authentication responses
Published Jun 16, 2024 · Updated Mar 14, 2025
Username enumeration in Shenzhen Guoxin Synthesis image system before 8.3.0 allows remote attackers to identify valid accounts via differing responses. The authentication path returns distinguishable incorrect and error outcomes for submitted usernames; public records do not identify the endpoint or response values. No prior authentication or user interaction is required; the disclosure is limited to account existence and can support follow-on credential attacks.
