Description
This security bulletin contains information about 1 vulnerability.
1) Type Confusion (CVE-ID: CVE-2020-8547)
CWE-ID: CWE-843 - Type confusion
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
phpList 3.5.0 allows type juggling for admin login bypass because == is used instead of === for password hashes, which mishandles hashes that begin with 0e followed by exclusively numerical characters.
Remediation
Install update from vendor's website.
