Descriptions
FreeRADIUS 2.2.x before 2.2.8 and 3.0.x before 3.0.9 does not properly check revocation of intermediate CA certificates.
FreeRADIUS 2.2.x en versiones anteriores a 2.2.8 y 3.0.x en versiones anteriores a 3.0.9 no comprueba adecuadamente la revocación de certificados CA intermedios.
The FreeRADIUS server relies on OpenSSL to perform certificate validation, including Certificate Revocation List (CRL) checks. The FreeRADIUS usage of OpenSSL, in CRL application, limits the checks to leaf certificates, therefore not detecting revocation of intermediate CA certificates. An unexpired client certificate, issued by an intermediate CA with a revoked certificate, is therefore accepted by FreeRADIUS. Versions equal to and below 2.2.7 and 3.0.8 are affected.
