etcd versions 3.2.x before 3.2.26 and 3.3.x before 3.3.11 are vulnerable to an improper authentication issue when role-based access control (RBAC) is used and client-cert-auth is enabled. If an etcd client server TLS certificate contains a Common Name (CN) which matches a valid RBAC username, a remote attacker may authenticate as that user with any valid (trusted) client certificate in a REST API request to the gRPC-gateway.
CWE-287
CVE-2018-16947
An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. The backup tape controller (butc) process accepts incoming RPCs but does not require (or allow for) authentication of those RPCs. Handling those RPCs results in operations being performed with administrator credentials, including dumping/restoring volume contents and manipulating the backup database. For example, an unauthenticated attacker can replace any volume’s content with arbitrary data.
CVE-2018-16877
A flaw was found in the way pacemaker’s client-server authentication was implemented in versions up to and including 2.0.0. A local attacker could use this flaw, and combine it with other IPC weaknesses, to achieve local privilege escalation.
CVE-2018-1672
IBM WebSphere Portal 7.0, 8.0, 8.5, and 9.0 may fail to set the correct user context in certain impersonation scenarios, which can allow a user to act with the identity of a different user. IBM X-Force ID: 144958.
CVE-2018-16737
tinc before 1.0.30 has a broken authentication protocol, without even a partial mitigation.
CVE-2018-16738
tinc 1.0.30 through 1.0.34 has a broken authentication protocol, although there is a partial mitigation. This is fixed in 1.1.
