SV-52489r3_rule The system must use a FIPS 140-2-approved cryptographic hashing algorithm for generating account password hashes.

Vulnerability discussion

Systems must employ cryptographic hashes for passwords using the SHA-2 family of algorithms or FIPS 140-2-approved successors. The use of unapproved algorithms may result in weak password hashes that are more vulnerable to compromise.

Check content

For Trusted Mode: MD5 is currently the only available hashing function. Per vendor documentation, this algorithm will not be updated, due to TS being deprecated/replaced by SMSE. For SMSE: Check the system password for use of cryptographic hashes using the SHA-2 family of algorithms or FIPS 140-2-approved successors. # egrep “CRYPT_ALGORITHMS_DEPRECATE|CRYPT_DEFAULT” /etc/default/security The following is an example output from the above command: CRYPT_ALGORITHMS_DEPRECATE=__unix__ CRYPT_DEFAULT=6 If the attributes “CRYPT_ALGORITHMS_DEPRECATE” and “CRYPT_DEFAULT” are not set per the above example output, this is a finding.

Fix text

For Trusted Mode: Note: There is no fix for Trusted Mode/Systems (TS). MD5 is currently used, and per vendor documentation, this algorithm will not be updated due to TS being deprecated/replaced by SMSE. For SMSE: Note: There may be additional package/bundle updates that must be installed to support attributes in the /etc/default/security file. Use the SAM/SMH interface (/etc/default/security file) to update the attribute. See the below example: CRYPT_ALGORITHMS_DEPRECATE=__unix__ CRYPT_DEFAULT=6 If manually editing the /etc/default/security file, save any change(s) before exiting the editor.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
