Freeradius: >> Freeradius >> 0.5 Security Vulnerabilities
RADIUS Protocol under RFC 2865 is susceptible to forgery attacks by a local attacker who can modify any valid Response (Access-Accept, Access-Reject, or Access-Challenge) to any other response using a chosen-prefix collision attack against MD5 Response Authenticator signature.

In freeradius, the EAP-PWD function compute_password_element() leaks information about the password which allows an attacker to substantially reduce the size of an offline dictionary attack.

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."

FreeRADIUS before 3.0.19 does not prevent use of reflection for authentication spoofing, aka a "Dragonblood" issue, a similar issue to CVE-2019-9497.

FreeRADIUS before 3.0.19 mishandles the "each participant verifies that the received scalar is within a range, and that the received group element is a valid point on the curve being used" protection mechanism, aka a "Dragonblood" issue, a similar issue to CVE-2019-9498 and CVE-2019-9499.

modules/rlm_unix/rlm_unix.c in FreeRADIUS before 2.2.0, when unix mode is enabled for user authentication, does not properly check the password expiration in /etc/shadow, which allows remote authenticated users to authenticate using an expired password.

The rad_decode function in FreeRADIUS before 1.1.8 allows remote attackers to cause a denial of service (radiusd crash) via zero-length Tunnel-Password attributes, as demonstrated by a certain module in VulnDisco Pack Professional 7.6 through 8.11. NOTE: this is a regression error related to CVE-2003-0967.

Memory leak in freeRADIUS 1.1.5 and earlier allows remote attackers to cause a denial of service (memory consumption) via a large number of EAP-TTLS tunnel connections using malformed Diameter format attributes, which causes the authentication request to be rejected but does not reclaim VALUE_PAIR data structures.

Buffer overflow in the SMB_Connect_Server function in FreeRadius 1.1.3 and earlier allows attackers to execute arbitrary code related to the server desthost field of an SMB_Handle_Type instance. NOTE: the impact of this issue has been disputed by a reliable third party and the vendor, who states that exploitation is limited "only to local administrators who have write access to the server configuration files." CVE concurs with the dispute
