CVE-2016-9847 (opens in a new tab)How to fix?
Upgrade Alpine:3.16 phpmyadmin to version 4.6.5.2-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream phpmyadmin package and not the phpmyadmin package as distributed by Alpine.
See How to fix? for Alpine:3.16 relevant fixed versions and status.
An issue was discovered in phpMyAdmin. When the user does not specify a blowfish_secret key for encrypting cookies, phpMyAdmin generates one at runtime. A vulnerability was reported where the way this value is created uses a weak algorithm. This could allow an attacker to determine the user's blowfish_secret and potentially decrypt their cookies. All 4.6.x versions (prior to 4.6.5), 4.4.x versions (prior to 4.4.15.9), and 4.0.x versions (prior to 4.0.10.18) are affected.
