The remote NewStart CGSL host, running version MAIN 6.06, has cyrus-sasl packages installed that are affected by multiple vulnerabilities:
cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of- service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl. (CVE-2019-19906)
In Cyrus SASL 2.1.17 through 2.1.27 before 2.1.28, plugins/sql.c does not escape the password for a SQL INSERT or UPDATE statement. (CVE-2022-24407)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
