K98008862: OpenLDAP vulnerability CVE-2019-13565
Original Publication Date: 15 Oct, 2019
Security Advisory Description
An issue was discovered in OpenLDAP 2.x before 2.4.48. When using SASL
authentication and session encryption, and relying on the SASL security layers
in slapd access controls, it is possible to obtain access that would otherwise
be denied via a simple bind for any identity covered in those ACLs. After the
first SASL bind is completed, the sasl_ssf value is retained for all new
non-SASL connections. Depending on the ACL configuration, this can affect
different types of operations (searches, modifications, etc.). In other words,
a successful authorization step completed by one user affects the authorization
requirement for a different user. (CVE-2019-13565).
Impact
Attackers may be able to obtain access to restricted resources.
