CVSS: 9.8EPSS: 0%CPEs: 21EXPL: 0CVE-2017-9148 – freeradius: TLS resumption authentication bypass
https://notcve.org/view.php?id=CVE-2017-9148
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. La caché de una sesión TLS en FreeRADIUS versiones 2.1.1 hasta 2.1.7, versiones 3.0.x anteriores a 3.0.14, versiones 3.1.x antes de 04-02-2017, y versiones 4.0.x antes de 04-02-2017, no puede impedir de manera fiable la reanudación de una sesión no autenticada, que permite a los atacantes remotos (como requirentes maliciosos 802.1X) para omitir la autenticación por medio de PEAP o TTLS. An authentication bypass flaw was found in the way the EAP module in FreeRADIUS handled TLS session resumption. A remote unauthenticated attacker could potentially use this flaw to bypass the inner authentication check in FreeRADIUS by resuming an older unauthenticated TLS session. • http://freeradius.org/security.html http://seclists.org/oss-sec/2017/q2/422 http://www.securityfocus.com/bid/98734 http://www.securitytracker.com/id/1038576 https://access.redhat.com/errata/RHSA-2017:1581 https://security.gentoo.org/glsa/201706-27 https://access.redhat.com/security/cve/CVE-2017-9148 https://bugzilla.redhat.com/show_bug.cgi?id=1456697 • CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2014-2015
Stack-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. Desbordamiento de buffer basado en pila en la función normify en el módulo rlm_pap (modules/rlm_pap/rlm_pap.c) en FreeRADIUS 2.x, posiblemente 2.2.3 y anteriores, y 3.x, posiblemente 3.0.1 y anteriores, podría permitir a atacantes causar una denagción de servicio (caída) y posiblemente ejecutar código arbitrario a través de un hash de contraseña largo, tal y como fue demostrado por un hash SSHA. A stack-based buffer overflow was found in the way the FreeRADIUS rlm_pap module handled long password hashes. An attacker able to make radiusd process a malformed password hash could cause the daemon to crash. • http://lists.freebsd.org/pipermail/freebsd-bugbusters/2014-February/000610.html http://lists.freebsd.org/pipermail/freebsd-bugbusters/2014-February/000612.html http://lists.freebsd.org/pipermail/freebsd-bugbusters/2014-February/000616.html http://rhn.redhat.com/errata/RHSA-2015-1287.html http://ubuntu.com/usn/usn-2122-1 http://www.openwall.com/lists/oss-security/2014/02/18/3 http://www.securityfocus.com/bid/65581 https://bugzilla.redhat.com/show_bug.cgi?id=1066761 https://acce • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
