CVSS: 9.8EPSS: 0%CPEs: 12EXPL: 0CVE-2019-11235 – freeradius: eap-pwd: authentication bypass via an invalid curve attack
https://notcve.org/view.php?id=CVE-2019-11235
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. FreeRADIUS versión anterior a 3.0.19 no maneja correctamente el mecanismo de protección "cada participante verifica que el escalar recibido está dentro de un rango, y que el elemento de grupo recibido es un punto válido en la curva que se está utilizando", alias "Dragonblood", este problema es similar a CVE-2019-9498 y CVE-2019-9499. A vulnerability was found in FreeRadius. An invalid curve attack allows an attacker to authenticate as any user, without knowing the password. FreeRADIUS doesn't verify whether the received elliptic curve point is valid. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00033.html https://access.redhat.com/errata/RHSA-2019:1131 https://access.redhat.com/errata/RHSA-2019:1142 https://bugzilla.redhat.com/show_bug.cgi?id=1695748 https://freeradius.org/release_notes/?br=3.0.x&re=3.0.19 https://freeradius.org/security https://papers.math • CWE-345: Insufficient Verification of Data Authenticity •
