https://notcve.org/view.php?id=CVE-2022-41861
A 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. • https://freeradius.org/security https://github.com/FreeRADIUS/freeradius-server/commit/0ec2b39d260e https://access.redhat.com/security/cve/CVE-2022-41861 https://bugzilla.redhat.com/show_bug.cgi?id=2078487 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2022-41860 – freeradius: Crash on unknown option in EAP-SIM
https://notcve.org/view.php?id=CVE-2022-41860
In 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. En freeradius, cuando un solicitante de EAP-SIM envía una opción SIM desconocida, el servidor intentará buscar esa opción en los diccionarios internos. Esta búsqueda fallará, pero el código SIM no verificará ese error. • https://freeradius.org/security https://github.com/FreeRADIUS/freeradius-server/commit/f1cdbb33ec61c4a64a https://access.redhat.com/security/cve/CVE-2022-41860 https://bugzilla.redhat.com/show_bug.cgi?id=2078485 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2019-17185
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. En FreeRADIUS versiones 3.0.x anteriores a 3.0.20, el módulo EAP-pwd utilizó una instancia OpenSSL BN_CTX global para manejar todos los protocolos de enlace. Esto significa que varios subprocesos utilizan la misma instancia de BN_CTX simultáneamente, resultando en bloqueos cuando los protocolos de enlace EAP-pwd son iniciados. • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00039.html https://freeradius.org/security https://github.com/FreeRADIUS/freeradius-server/releases/tag/release_3_0_20 https://access.redhat.com/security/cve/CVE-2019-17185 https://bugzilla.redhat.com/show_bug.cgi?id=1816680 • CWE-567: Unsynchronized Access to Shared Data in a Multithreaded Context CWE-662: Improper Synchronization •
CVSS: 6.5EPSS: 0%CPEs: 5EXPL: 2CVE-2019-13456 – freeradius: eap-pwd: Information leak due to aborting when needing more than 10 iterations
https://notcve.org/view.php?id=CVE-2019-13456
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. En FreeRADIUS versiones 3.0 hasta 3.0.19, en promedio 1 de cada 2048 protocolos de enlace EAP-pwd presenta un fallo porque el elemento de contraseña no puede ser encontrado dentro de las 10 iteraciones del bucle de tipo "hunting and pecking". Esto filtra información que un atacante puede utilizar para recuperar la contraseña de cualquier usuario. • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00039.html https://bugzilla.redhat.com/show_bug.cgi?id=1737663 https://freeradius.org/security https://github.com/FreeRADIUS/freeradius-server/commit/3ea2a5a026e73d81cd9a3e9bbd4300c433004bfa https://wpa3.mathyvanhoef.com https://access.redhat.com/security/cve/CVE-2019-13456 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
CVSS: 7.0EPSS: 0%CPEs: 4EXPL: 2CVE-2019-10143 – freeradius: privilege escalation due to insecure logrotate configuration
https://notcve.org/view.php?id=CVE-2019-10143
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." ** EN DISPUTA **Se encontró que freeradius hasta la versión 3.0.19 incluyéndola, no configura correctamente el componente logrotate, lo que permite que un atacante local que ya tiene el control del usuario radiusd escale sus privilegios a root, engañando a logrotate para que escriba un archivo escribible en radiusd en un directorio normalmente inaccesible para el usuario radiusd. NOTA: el mantenedor de software upstream ha declarado que "simplemente no hay forma de que alguien obtenga privilegios a través de este supuesto problema" 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. FreeRadius versions 3.0.19 and below suffer from a privilege escalation vulnerability via insecure logrotate use. • http://packetstormsecurity.com/files/155361/FreeRadius-3.0.19-Logrotate-Privilege-Escalation.html http://seclists.org/fulldisclosure/2019/Nov/14 https://access.redhat.com/errata/RHSA-2019:3353 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10143 https://freeradius.org/security https://github.com/FreeRADIUS/freeradius-server/pull/2666 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/A6VKBZAZKJP5QKXDXRKCM2ZPZND3TFAX https://lists.fedoraproject.org/archives/list/ • CWE-250: Execution with Unnecessary Privileges CWE-266: Incorrect Privilege Assignment CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
