CVE-2026-35563 (GCVE-0-2026-35563)

Vulnerability from nvd – Published: 2026-06-01 07:12 – Updated: 2026-06-01 13:09

Title
Apache Directory LDAP API: LDAP client implementation does not verify if the server certificate matches the intended LDAP hostname
Summary
It was identified that the LDAP client implementation in version 2.1.7 does not verify if the server certificate matches the intended LDAP hostname. While the underlying code validates the certificate chain against a trusted authority, the absence of endpoint identification allows a valid certificate issued for an entirely unrelated host to be improperly accepted. This oversight leaves the connection highly vulnerable to server impersonation and complete connection compromise. The root cause of this vulnerability lies in the incomplete TLS server identity verification within the LDAP client implementation. The attacker requires MITM capability on the network to exploit this vulnerability. This attacker must be able to present a certificate trusted by the client's configured trust store. The hostname verification has been enforced in the new version of the LDAP API

CVE-2018-1337 (GCVE-0-2018-1337)

Vulnerability from nvd – Published: 2018-07-10 13:00 – Updated: 2024-09-17 01:12
VLAI
Summary
In Apache Directory LDAP API before 1.0.2, a bug in the way the SSL Filter was setup made it possible for another thread to use the connection before the TLS layer has been established, if the connection has already been used and put back in a pool of connections, leading to leaking any information contained in this request (including the credentials when sending a BIND request).
Severity
No CVSS data available.

CVE-2026-35563 (GCVE-0-2026-35563)

Vulnerability from cvelistv5 – Published: 2026-06-01 07:12 – Updated: 2026-06-01 13:09

Title
Apache Directory LDAP API: LDAP client implementation does not verify if the server certificate matches the intended LDAP hostname
Summary
It was identified that the LDAP client implementation in version 2.1.7 does not verify if the server certificate matches the intended LDAP hostname. While the underlying code validates the certificate chain against a trusted authority, the absence of endpoint identification allows a valid certificate issued for an entirely unrelated host to be improperly accepted. This oversight leaves the connection highly vulnerable to server impersonation and complete connection compromise. The root cause of this vulnerability lies in the incomplete TLS server identity verification within the LDAP client implementation. The attacker requires MITM capability on the network to exploit this vulnerability. This attacker must be able to present a certificate trusted by the client's configured trust store. The hostname verification has been enforced in the new version of the LDAP API

CVE-2018-1337 (GCVE-0-2018-1337)

Summary
In Apache Directory LDAP API before 1.0.2, a bug in the way the SSL Filter was setup made it possible for another thread to use the connection before the TLS layer has been established, if the connection has already been used and put back in a pool of connections, leading to leaking any information contained in this request (including the credentials when sending a BIND request).
