CVE-2009-3111 WRITEUP WRITEUP
FreeRADIUS < 1.1.8 - Denial of Service via Zero-Length Tunnel-Password Attribute
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.
CVE-2022-41859 WRITEUP HIGH WRITEUP
FreeRADIUS < 3.0.0 - Insufficiently Protected Credentials via EAP-PWD Password Element
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.
CVSS 7.5
CVE-2022-41860 WRITEUP HIGH WRITEUP
Freeradius - Use After Free
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.
CVSS 7.5
CVE-2022-41861 WRITEUP MEDIUM WRITEUP
FreeRADIUS < 3.0.25 - Denial of Service via Malformed Abinary Attribute
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.
CVSS 6.5
