CVE-2021-38135Network attack vector

Unauthenticated outbound requests via undisclosed endpoint

Published Nov 22, 2024 · Updated Nov 25, 2024

Server-side request forgery in OpenText iManager 3.0.0 through 3.2.5.0000 allows remote attackers to send outbound requests. OpenText identifies SSRF and uncontrolled network-message volume, but has not disclosed the affected endpoint or how it accepts and dispatches an attacker-controlled destination. The interface is reachable without authentication or user interaction, and exploitation can modify resources outside iManager's security authority; no confidentiality or availability impact is reported.
