Description Pedro Sampaio 2018-03-26 15:41:26 UTC

When generating an HTTP Digest authentication challenge, the nonce
sent to prevent reply attacks was not correctly generated using a
pseudo-random seed.  In a cluster of servers using a common Digest
authentication configuration, HTTP requests could be replayed across
servers by an attacker without detection.

Versions Affected:
httpd 2.2.0 to 2.4.29

Comment 7 Huzaifa S. Sidhpurwala 2018-06-22 04:43:50 UTC

Statement:

The "AuthType Digest" directive is not enabled in the default httpd configuration as shipped with Red Hat Enterprise Linux, and needs to be explicitly enabled. Therefore this flaw has no impact on the default versions of the httpd package as shipped with Red Hat Enterprise Linux. Also upstream discourages the use of mod_auth_digest because of its inherent security weaknesses and recommends the use of mod_ssl.
