CVSS v3.1 |
modules/rlm_unix/rlm_unix.c in FreeRADIUS before 2.2.0, when unix mode is enabled for user authentication, does not properly check the password expiration in /etc/shadow, which allows remote authenticated users to authenticate using an expired password. |
The wait_for_child_to_die function in main/event.c in FreeRADIUS 2.1.x before 2.1.10, in certain circumstances involving long-term database outages, does not properly handle long queue times for requests, which allows remote attackers to cause a denial of service (daemon crash) by sending many requests. |
The rad_decode function in FreeRADIUS before 1.1.8 allows remote attackers to cause a denial of service (radiusd crash) via zero-length Tunnel-Password attributes, as demonstrated by a certain module in VulnDisco Pack Professional 7.6 through 8.11. NOTE: this is a regression error related to CVE-2003-0967. |
Buffer overflow in the SMB_Connect_Server function in FreeRadius 1.1.3 and earlier allows attackers to execute arbitrary code related to the server desthost field of an SMB_Handle_Type instance. NOTE: the impact of this issue has been disputed by a reliable third party and the vendor, who states that exploitation is limited "only to local administrators who have write access to the server configuration files." CVE concurs with the dispute |
freeradius-dialupadmin in freeradius 2.0.4 allows local users to overwrite arbitrary files via a symlink attack on temporary files in (1) backup_radacct, (2) clean_radacct, (3) monthly_tot_stats, (4) tot_stats, and (5) truncate_radacct. |
Memory leak in freeRADIUS 1.1.5 and earlier allows remote attackers to cause a denial of service (memory consumption) via a large number of EAP-TTLS tunnel connections using malformed Diameter format attributes, which causes the authentication request to be rejected but does not reclaim VALUE_PAIR data structures. |
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. |
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. |
In freeradius, the EAP-PWD function compute_password_element() leaks information about the password which allows an attacker to substantially reduce the size of an offline dictionary attack. |
SQL injection vulnerability in the rlm_sqlcounter module in FreeRADIUS 1.0.3 and 1.0.4 allows remote attackers to execute arbitrary SQL commands via unknown attack vectors. |
FreeRADIUS before 1.0.1 allows remote attackers to cause a denial of service (server crash) by sending an Ascend-Send-Secret attribute without the required leading packet. |
SQL injection vulnerability in the radius_xlat function in the SQL module for FreeRADIUS 1.0.2 and earlier allows remote authenticated users to execute arbitrary SQL commands via (1) group_membership_query, (2) simul_count_query, or (3) simul_verify_query configuration entries. |
Unspecified vulnerability in FreeRADIUS 1.0.0 up to 1.1.0 allows remote attackers to bypass authentication or cause a denial of service (server crash) via "Insufficient input validation" in the EAP-MSCHAPv2 state machine module. |
Multiple buffer overflows in FreeRADIUS 1.0.3 and 1.0.4 allow remote attackers to cause denial of service (crash) via (1) the rlm_sqlcounter module or (2) unknown vectors "while expanding %t". |
Off-by-one error in the sql_error function in sql_unixodbc.c in FreeRADIUS 1.0.2.5-5, and possibly other versions including 1.0.4, might allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by causing the external database query to fail. NOTE: this single issue is part of a larger-scale disclosure, originally by SUSE, which reported multiple issues that were disputed by FreeRADIUS. Disputed issues included file descriptor leaks, memory disclosure, LDAP injection, and other issues. Without additional information, the most recent FreeRADIUS report is being regarded as the authoritative source for this CVE identifier. |
Multiple RADIUS implementations do not properly validate the Vendor-Length of the Vendor-Specific attribute, which allows remote attackers to cause a denial of service (crash) via a Vendor-Length that is less than 2. |
rad_decode in FreeRADIUS 0.9.2 and earlier allows remote attackers to cause a denial of service (crash) via a short RADIUS string attribute with a tag, which causes memcpy to be called with a -1 length argument, as demonstrated using the Tunnel-Password attribute. |
Stack-based buffer overflow in SMB_Logon_Server of the rlm_smb experimental module for FreeRADIUS 0.9.3 and earlier allows remote attackers to execute arbitrary code via a long User-Password attribute. |
FreeRADIUS RADIUS server allows remote attackers to cause a denial of service (CPU consumption) via a flood of Access-Request packets. |
Buffer overflow in the sql_escape_func function in the SQL module for FreeRADIUS 1.0.2 and earlier allows remote attackers to cause a denial of service (crash). |
