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. 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)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
