A vulnerability classified as problematic has been found in Juniper Junos (Router Operating System). This affects an unknown functionality of the file pam_radius.conf of the component RADIUS. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality, and integrity.

The weakness was released 10/08/2014 with Juniper as JSA10654 as confirmed advisory (Website). The advisory is shared at kb.juniper.net. This vulnerability is uniquely identified as CVE-2014-6379 since 09/11/2014. The exploitability is told to be easy. It is possible to initiate the attack remotely. The successful exploitation needs a authentication. Technical details are known, but no exploit is available. The advisory points out:

In Junos, when a RADIUS authentication server is configured under [system radius-server], an entry is created in /var/etc/pam_radius.conf. An issue was discovered where RADIUS accounting servers configured under [system accounting destination radius] are also propagated to pam_radius.conf. This can cause authentication requests to be sent to the RADIUS accounting server which may allow for unintended successful authentication. If the same RADIUS server is used for both authentication and accounting — a common configuration — the issue is less severe since RADIUS authentication is sent to the intended server despite the duplicate entries. However, if the RADIUS authentication server is later removed from the configuration, the duplicate entry created by configuration of the RADIUS accounting server will remain in pam_radius.conf, also leading to possible unintended authentication success.

The vulnerability scanner Nessus provides a plugin with the ID 78425 , which helps to determine the existence of the flaw in a target environment. It is .
