CVE-2021-33256 describes a CSV injection vulnerability in ManageEngine ADSelfService Plus version 6.1 Build 6101, specifically within the login panel's j_username parameter. This high-severity vulnerability (CVSS 8.8) could allow an unauthenticated attacker to achieve a reverse shell if a privileged user exports the "User Attempts Audit Report" as a CSV file. While the vendor disputes its validity, the attack requires user interaction (UI:R) but has low attack complexity (AC:L) and no authentication (PR:N), leading to high confidentiality, integrity, and availability impacts (C:H/I:H/A:H). Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
