CVE-2024-27310Network attack vector

Service interruption and information exposure via LDAP injection

Published May 27, 2024 · Updated Oct 7, 2024

LDAP injection in Zoho Corporation ManageEngine ADSelfService Plus 6400 and earlier allows remote attackers to overload the server. During passwordless login, the server places malicious input into an LDAP query without sanitization, allowing queries for multiple users. Unauthenticated network access to the passwordless login flow is sufficient; impacts are limited to unauthorized user information exposure and service interruption.
