CVE-2016-6622: n/a vulnerability

CVE-2016-6622: An issue was discovered in phpMyAdmin.

An issue was discovered in phpMyAdmin. An unauthenticated user is able to execute a denial-of-service (DoS) attack by forcing persistent connections when phpMyAdmin is running with $cfg['AllowArbitraryServer']=true. All 4.6.x versions (prior to 4.6.4), 4.4.x versions (prior to 4.4.15.8), and 4.0.x versions (prior to 4.0.10.17) are affected.

Security readout for executives and security teams

This flaw lets an unauthenticated attacker make vulnerable phpMyAdmin instances consume resources and become unavailable. The issue depends on phpMyAdmin allowing arbitrary server selection. It is an availability risk, not a sourced data theft or code execution issue. Exposure is most likely on internet-facing or broadly reachable phpMyAdmin deployments using the affected versions and AllowArbitraryServer enabled. Systems updated through vendor packages may be fixed by distribution security updates. Treat as a near-term availability issue for exposed administrative tooling. Prioritize internet-facing phpMyAdmin instances first, especially where service disruption would affect operations or incident response. Mitigation focus: Upgrade phpMyAdmin to a fixed branch version or later.; Apply relevant Debian or Gentoo security updates where applicable.; Disable AllowArbitraryServer if the feature is not required..
