CVE-2020-11814Public exploitNetwork attack vector

User redirection via spoofed Host header

Published Apr 16, 2020 · Updated Aug 4, 2024

Host header injection in qdPM 9.1 allows remote attackers to redirect users to malicious websites through a spoofed HTTP Host header. Published material does not identify the qdPM code path that trusts the attacker-supplied Host value or explain how it enters a redirect. Exploitation requires user interaction, and the reported consequence is limited to steering that user to an attacker-chosen malicious website.
