CVE-2018-1312: Weak Digest auth nonce generation in mod_auth_digest Severity: Low
Vendor: The Apache Software Foundation Versions Affected: httpd 2.2.0 to 2.4.29 Description: 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. Mitigation: All httpd users should upgrade to 2.4.30 or later. Credit: The issue was discovered by Nicolas Daniels. References: https://httpd.apache.org/security/vulnerabilities_24.html
