Top vulnerabilities
CVE-2024-3596RADIUS 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.
CVE-2019-11235FreeRADIUS 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.
CVE-2017-10984An FR-GV-301 issue in FreeRADIUS 3.x before 3.0.15 allows "Write overflow in data2vp_wimax()" - this allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code.
CVE-2017-10979An FR-GV-202 issue in FreeRADIUS 2.x before 2.2.10 allows "Write overflow in rad_coalesce()" - this allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code.
CVE-2015-8764Off-by-one error in the EAP-PWD module in FreeRADIUS 3.0 through 3.0.8, which triggers a buffer overflow.
CVE-2015-8763The EAP-PWD module in FreeRADIUS 3.0 through 3.0.8 allows remote attackers to have unspecified impact via a crafted (1) commit or (2) confirm message, which triggers an out-of-bounds read.
CVE-2005-4746Multiple buffer overflows in FreeRADIUS 1.0.3 and 1.0.4 allow remote attackers to cause denial of service (crash) via (1) the rlm_sqlcounter module or (2) unknown vectors "while expanding %t".
CVE-2022-41861A flaw was found in freeradius. A malicious RADIUS client or home server can send a malformed abinary attribute which can cause the server to crash.
CVE-2022-41860In freeradius, when an EAP-SIM supplicant sends an unknown SIM option, the server will try to look that option up in the internal dictionaries. This lookup will fail, but the SIM code will not check for that failure. Instead, it will dereference a NULL pointer, and cause the server to crash.
CVE-2022-41859In 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.
CVE-2019-17185In 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-2015-4680FreeRADIUS 2.2.x before 2.2.8 and 3.0.x before 3.0.9 does not properly check revocation of intermediate CA certificates.
CVE-2006-1354Unspecified vulnerability in FreeRADIUS 1.0.0 up to 1.1.0 allows remote attackers to bypass authentication or cause a denial of service (server crash) via "Insufficient input validation" in the EAP-MSCHAPv2 state machine module.
CVE-2005-4745SQL injection vulnerability in the rlm_sqlcounter module in FreeRADIUS 1.0.3 and 1.0.4 allows remote attackers to execute arbitrary SQL commands via unknown attack vectors.
CVE-2005-1455Buffer overflow in the sql_escape_func function in the SQL module for FreeRADIUS 1.0.2 and earlier allows remote attackers to cause a denial of service (crash).
CVE-2005-1454SQL injection vulnerability in the radius_xlat function in the SQL module for FreeRADIUS 1.0.2 and earlier allows remote authenticated users to execute arbitrary SQL commands via (1) group_membership_query, (2) simul_count_query, or (3) simul_verify_query configuration entries.
CVE-2001-1376Buffer overflow in digest calculation function of multiple RADIUS implementations allows remote attackers to cause a denial of service and possibly execute arbitrary code via shared secret data.
CVE-2017-9148The TLS session cache in FreeRADIUS 2.1.1 through 2.1.7, 3.0.x before 3.0.14, 3.1.x before 2017-02-04, and 4.0.x before 2017-02-04 fails to reliably prevent resumption of an unauthenticated session, which allows remote attackers (such as malicious 802.1X supplicants) to bypass authentication via PEAP or TTLS.
CVE-2008-4474freeradius-dialupadmin in freeradius 2.0.4 allows local users to overwrite arbitrary files via a symlink attack on temporary files in (1) backup_radacct, (2) clean_radacct, (3) monthly_tot_stats, (4) tot_stats, and (5) truncate_radacct.
CVE-2007-0080Buffer 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
CVE-2014-2015Stack-based buffer overflow in the normify function in the rlm_pap module (modules/rlm_pap/rlm_pap.c) in FreeRADIUS 2.x, possibly 2.2.3 and earlier, and 3.x, possibly 3.0.1 and earlier, might allow attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long password hash, as demonstrated by an SSHA hash.
CVE-2019-10143It 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-2005-4744Off-by-one error in the sql_error function in sql_unixodbc.c in FreeRADIUS 1.0.2.5-5, and possibly other versions including 1.0.4, might allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by causing the external database query to fail. NOTE: this single issue is part of a larger-scale disclosure, originally by SUSE, which reported multiple issues that were disputed by FreeRADIUS. Disputed issues included file descriptor leaks, memory disclosure, LDAP injection, and other issues. Without additional information, the most recent FreeRADIUS report is being regarded as the authoritative source for this CVE identifier.
CVE-2017-10987An FR-GV-304 issue in FreeRADIUS 3.x before 3.0.15 allows "DHCP - Buffer over-read in fr_dhcp_decode_suboptions()" and a denial of service.
CVE-2017-10986An FR-GV-303 issue in FreeRADIUS 3.x before 3.0.15 allows "DHCP - Infinite read in dhcp_attr2vp()" and a denial of service.
