Security Fix(es) :

  - freeradius: privilege escalation due to insecure     logrotate configuration (CVE-2019-10143)

  - freeradius: eap-pwd: Information leak due to aborting     when needing more than 10 iterations (CVE-2019-13456)

  - freeradius: eap-pwd: DoS issues due to multithreaded     BN_CTX access (CVE-2019-17185)

The version of freeradius installed on the remote host is prior to 3.0.13-15. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1515 advisory.

    It was discovered freeradius does not correctly configure logrotate, allowing a local attacker who already     has control of the radiusd user to escalate his privileges to root, by tricking logrotate into writing a     radiusd-writable file to a directory normally inaccessible by the radiusd user. (CVE-2019-10143)

    An information leak was discovered in the implementation of EAP-pwd in freeradius. An attacker could     initiate several EAP-pwd handshakes to leak information, which can then be used to recover the user's WiFi     password by performing dictionary and brute-force attacks. (CVE-2019-13456)

    In FreeRADIUS 3.0.x before 3.0.20, the EAP-pwd module used a global OpenSSL BN_CTX instance to handle all     handshakes. This mean multiple threads use the same BN_CTX instance concurrently, resulting in crashes     when concurrent EAP-pwd handshakes are initiated. This can be abused by an adversary as a Denial-of-     Service (DoS) attack. (CVE-2019-17185)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has freeradius packages installed that are affected by multiple vulnerabilities:

  - ** DISPUTED ** It was discovered freeradius up to and including version 3.0.19 does not correctly     configure logrotate, allowing a local attacker who already has control of the radiusd user to escalate his     privileges to root, by tricking logrotate into writing a radiusd-writable file to a directory normally     inaccessible by the radiusd user. NOTE: the upstream software maintainer has stated there is simply no     way for anyone to gain privileges through this alleged issue. (CVE-2019-10143)

  - In FreeRADIUS 3.0 through 3.0.19, on average 1 in every 2048 EAP-pwd handshakes fails because the password     element cannot be found within 10 iterations of the hunting and pecking loop. This leaks information that     an attacker can use to recover the password of any user. This information leakage is similar to the     Dragonblood attack and CVE-2019-9494. (CVE-2019-13456)

  - In FreeRADIUS 3.0.x before 3.0.20, the EAP-pwd module used a global OpenSSL BN_CTX instance to handle all     handshakes.
