CVE-2023-6905Network attack vector

Authenticated LDAP query manipulation via bind test

Published Dec 17, 2023 · Updated Aug 2, 2024

LDAP injection in the Bind Request Handler in Jahastech NxFilter 4.3.2.5 allows remote authenticated users to alter LDAP queries. The user,adap.jsp test action incorporates attacker-controlled bind-request data into an LDAP query without neutralizing LDAP metacharacters. Access to the authenticated bind-test interface is required; public records disclose neither the injectable parameter nor the resulting directory operation.
