CVE-2012-3547debianfreeradius+21
EPSS score5.70%
Stack-based buffer overflow in the cbtls_verify function in FreeRADIUS 2.1.10 through 2.1.12, when using TLS-based EAP methods, allows remote attackers to cause a denial of service (server crash) and possibly execute arbitrary code via a long "not after" timestamp in a client certificate.CVE-2011-2701freeradiusfreeradiusEPSS score1.85%
The ocsp_check function in rlm_eap_tls.c in FreeRADIUS 2.1.11, when OCSP is enabled, does not properly parse replies from OCSP responders, which allows remote attackers to bypass authentication by using the EAP-TLS protocol with a revoked X.509 client certificate.CVE-2011-4966debianfreeradius+21EPSS score1.38%
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.CVE-2010-3697debianfreeradius+1EPSS score2.21%
The wait_for_child_to_die function in main/event.c in FreeRADIUS 2.1.x before 2.1.10, in certain circumstances involving long-term database outages, does not properly handle long queue times for requests, which allows remote attackers to cause a denial of service (daemon crash) by sending many requests.CVE-2010-3696debianfreeradius+1EPSS score1.62%
The fr_dhcp_decode function in lib/dhcp.c in FreeRADIUS 2.1.9, in certain non-default builds, does not properly handle the DHCP Relay Agent Information option, which allows remote attackers to cause a denial of service (infinite loop and daemon outage) via a packet that has more than one sub-option. NOTE: some of these details are obtained from third party information.CVE-2017-9148debianfreeradius+19EPSS score3.91%
The 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-2017-10985debianfreeradius+1EPSS score3.27%
An FR-GV-302 issue in FreeRADIUS 3.x before 3.0.15 allows "Infinite loop and memory exhaustion with 'concat' attributes" and a denial of service.CVE-2017-10980debianfreeradius+2EPSS score3.37%
An FR-GV-203 issue in FreeRADIUS 2.x before 2.2.10 allows "DHCP - Memory leak in decode_tlv()" and a denial of service.CVE-2017-10986debianfreeradius+1EPSS score2.99%
An FR-GV-303 issue in FreeRADIUS 3.x before 3.0.15 allows "DHCP - Infinite read in dhcp_attr2vp()" and a denial of service.CVE-2017-10982debianfreeradius+2EPSS score3.84%
An FR-GV-205 issue in FreeRADIUS 2.x before 2.2.10 allows "DHCP - Buffer over-read in fr_dhcp_decode_options()" and a denial of service.CVE-2017-10983debianfreeradius+2EPSS score3.38%
An FR-GV-206 issue in FreeRADIUS 2.x before 2.2.10 and 3.x before 3.0.15 allows "DHCP - Read overflow when decoding option 63" and a denial of service.CVE-2017-10987debianfreeradius+1EPSS score2.99%
An 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-2017-10981debianfreeradius+2EPSS score3.37%
An FR-GV-204 issue in FreeRADIUS 2.x before 2.2.10 allows "DHCP - Memory leak in fr_dhcp_decode()" and a denial of service.CVE-2017-10984debianfreeradius+1EPSS score6.41%
An 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-2017-10979debianfreeradius+2EPSS score7.04%
An 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-2017-10978debianfreeradius+9EPSS score3.81%
An FR-GV-201 issue in FreeRADIUS 2.x before 2.2.10 and 3.x before 3.0.15 allows "Read / write overflow in make_secret()" and a denial of service.CVE-2004-0960debianfreeradius+3EPSS score3.23%
FreeRADIUS before 1.0.1 allows remote attackers to cause a denial of service (core dump) via malformed USR vendor-specific attributes (VSA) that cause a memcpy operation with a -1 argument.CVE-2004-0961debianfreeradius+3EPSS score3.26%
Memory leak in FreeRADIUS before 1.0.1 allows remote attackers to cause a denial of service (memory exhaustion) via a series of Access-Request packets with (1) Ascend-Send-Secret, (2) Ascend-Recv-Secret, or (3) Tunnel-Password attributes.CVE-2004-0938debianfreeradius+1EPSS score3.65%
FreeRADIUS before 1.0.1 allows remote attackers to cause a denial of service (server crash) by sending an Ascend-Send-Secret attribute without the required leading packet.CVE-2024-3596alpinefreeradius+75EPSS score14.86%
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.
