[GLSA-200505-13] FreeRADIUS: SQL injection and Denial of Service vulnerability Vulnerability Scan
Vulnerability Scan Summary
FreeRADIUS: SQL injection and Denial of Service vulnerability
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200505-13
(FreeRADIUS: SQL injection and Denial of Service vulnerability)
Primoz Bratanic discovered that the sql_escape_func function of
FreeRADIUS may be vulnerable to a buffer overflow (BID 13541). He also
discovered that FreeRADIUS fails to sanitize user-input before using it
in a SQL query, possibly allowing SQL command injection (BID 13540).
Impact
By supplying carefully crafted input, a malicious user could cause an
SQL injection or a buffer overflow, possibly leading to the disclosure
and the modification of sensitive data or Denial of Service by crashing
the server.
Workaround
There are no known workarounds at this time.
