A vulnerability was found in phpMyAdmin up to 4.6.3/4.4.15.7/4.0.10.16 (Database Administration Software) and classified as critical. Affected by this issue is an unknown functionality of the component SaveDir/UploadDir. The manipulation of the argument username

Impacted is confidentiality, and integrity. CVE summarizes:
