CVE-2020-27181: Use of Hard-coded Credentials

A hardcoded AES key in CipherUtils.java in the Java applet of konzept-ix publiXone before 2020.015 allows attackers to craft password-reset tokens or decrypt server-side configuration files...

Design/Logic Flaw

On BIG-IP 14.1.0-14.1.0.5, 14.0.0-14.0.0.4, 13.0.0-13.1.1.4, and 12.1.0-12.1.4, under certain circumstances, attackers can decrypt configuration items that are encrypted because the vCMP configuration unit key is generated with insufficient randomness. The attack prerequisite is direct access to...

CVE-2019-6632

CVE-2019-6632 affects BIG-IP vCMP: the vCMP configuration unit key is generated with insufficient randomness, enabling decryption of encrypted configuration/UCS files when an attacker has direct access to those files. Affected: BIG-IP versions 12.1.0–12.1.4, 13.0.0–13.1.1.4, 14.0.0–14.0.0.4/14.0....
