Doc Text:	Apache Karaf uses the LDAPLoginModule to authenticate users to a directory via LDAP. It does not, however, encode usernames properly and hence is vulnerable to LDAP injection attacks. While it appears that it is not possible to exploit this vulnerability to allow an attacker to gain remote access, it does allow an attacker to insert special characters into the search query step. Therefore, it can potentially be exploited as part of a Denial of Service attack.	Story Points:	---

Description Andrej Nemec 2017-12-11 13:47:48 UTC

Apache Karaf uses the LDAPLoginModule to authenticate users to a directory
via LDAP. However, it is not encoding usernames properly and hence is
vulnerable to LDAP injection attacks.

While it appears that it not possible to exploit this vulnerability to allow
an attacker to gain remote access, it allows an attacker to insert special
characters into the search query step. Therefore, it can potentially be
exploited as part of a Denial Of Service attack.
