FreeRADIUS: Authentication bypass in EAP-MSCHAPv2 module

Background FreeRADIUS is an open source RADIUS authentication server implementation. Description FreeRADIUS suffers from insufficient input validation in the EAP-MSCHAPv2 state machine. Impact An attacker could cause the server to bypass authentication checks by manipulating the EAP-MSCHAPv2 clie...

SUSE-SA:2006:019: freeradius

The remote host is missing the patch for the advisory SUSE-SA:2006:019 freeradius. Insufficient input validation was being done in the EAP-MSCHAPv2 state machine of the FreeRADIUS authentication server. A malicious attacker could manipulate their EAP-MSCHAPv2 client state machine to potentially...

CVE-2005-4744

FreeRADIUS contains an off-by-one error in sql_error (sql_unixodbc.c) affecting at least 1.0.2-4 and 1.0.2.5-5, with later versions also referenced. CVE-2005-4744 may allow remote attackers to cause denial of service (crash) and possibly execute arbitrary code by forcing a failing external databa...

CVE-2005-4746

CVE-2005-4746 pertains to FreeRADIUS 1.0.3 and 1.0.4, where multiple buffer overflows in the server (notably in the rlm_sqlcounter module and other vectors described as those occurring while expanding %t) can cause denial of service. The connected advisories from Debian (DSA-1145-1) and vendor di...

CVE-2005-4745

CVE-2005-4745 is a SQL injection vulnerability in the rlm_sqlcounter module of FreeRADIUS 1.0.3 and 1.0.4. The issue permits remote attackers to execute arbitrary SQL commands via unknown attack vectors. Documentation in multiple advisories (e.g., Debian DSA-1145-1) corroborates the SQL injection...
