CVE-2016-9847
phpMyAdmin Cryptographic Vulnerability
Also known as GHSA-9xhq-pm7v-693p
Published 9 y ago · modified 4 mo ago · JSON
Summary
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.
Exploit prediction (EPSS)
2.00% probability of exploitation in the next 30 days, higher than 81% of all scored CVEs.
