CVE-2016-9847
MEDIUMphpMyAdmin 4.0.x < 4.0.10.18, 4.4.x < 4.4.15.9, 4.6.x < 4.6.5 - Weak Cookie Encryption Key Generation
Title source: llmDescription
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.
