Description:
Primoz Bratanic has reported some vulnerabilities in FreeRADIUS, which potentially can be exploited by malicious users to conduct SQL injection attacks or to cause a DoS (Denial of Service).
1) A boundary error in the "sql_escape_func()" function in rlm_sql.c can potentially be exploited to cause a buffer overflow via specially crafted input that needs escaping.
Successful exploitation crashes the application.
2) Missing sanitation when calling the "radius_xlat()" function in rlm_sql.c can potentially be exploited by authenticated users to manipulate SQL queries by injecting arbitrary SQL code.
Solution:
The vulnerabilities have been fixed in version 1.0.3.
Provided and/or discovered by:
Primoz Bratanic
