Descrição técnica

LibreNMS before 26.9.0 contains an LDAP filter injection in ldap-authorization and ad-authorization modes because usernames are inserted unescaped into LDAP search filters and authentication only checks user existence. When REMOTE_USER is not forwarded, unauthenticated attackers can send a wildcard username via HTTP Basic Authorization (PHP_AUTH_USER) to match all users and groups and gain admin access.

——9SEPPmail Secure Email Gateway before 15.1.1 does not neutralize LDAP metacharacters in an unauthenticated account-selection input in its GINA web interface. A remote unauthenticated attacker can enumerate email addresses.3d CVE-2026-936364.3 MÉD

——8An LDAP filter injection vulnerability in Zimbra Collaboration Suite (ZCS) allows an authenticated user to query otherwise unreturned attributes of calendar resources through SearchCalendarResourcesRequest. Zimbra escapes search values but inserts the supplied attribute names directly into LDAP filter expressions without validation. An attacker can inject additional conditions and use repeated matching queries to recover readable resource attributes such as internal mailbox hostnames and mail transport routes. The search remains restricted to calendar-resource objects and the LDAP service account's access rights. ZCS 10.1.16 and 10.1.21 are affected.9d CVE-2026-157238.2 ALT

——14GitLab has remediated an issue in GitLab CE/EE affecting all versions from 10.1 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, when OmniAuth SAML and LDAP auto-linking were both enabled, an authenticated user could have taken over an existing LDAP-backed account without any interaction from the targeted user, due to improper input sanitization in the LDAP email lookup path used during OmniAuth identity linking.2d CVE-2026-936355.3 MÉD

——5LDAP filter injection in Zimbra Collaboration Suite 10.1.0 through 10.1.21 allows unauthenticated attackers to alter external LDAP search filters. On domains using search-filter authentication and lazy provisioning, this creates a password oracle for external directory users. Authenticated S/MIME lookups can also return certificates and identity data for unintended directory entries.21d CVE-2026-890717.5 ALT

——9Finsys Dockhand through 1.0.18 contains an LDAP injection vulnerability in the tryLdapAuth function in src/lib/server/auth.ts, which inserts the login username into the LDAP search filter without escaping wildcard characters. Unauthenticated attackers can submit incremental wildcard patterns such as 'a*' to /api/auth/login and measure response timing to enumerate valid LDAP usernames while evading per-username rate limiting.11d
