What is CVE-2020-9495?

The login service in Apache Archiva versions prior to 2.2.5 is susceptible to LDAP injection attacks. An attacker can exploit this vulnerability by entering specially crafted input into the login form. This input can manipulate the LDAP filter, potentially exposing sensitive user attribute data stored in the connected LDAP server. By analyzing the response times of login attempts, adversaries can gain unauthorized access to critical information about LDAP user objects, posing a significant risk to data integrity and privacy.

Affected Version(s)

Apache Archiva Apache Archiva 2.2.4 and below

Exploit Proof of Concept (PoC)
