CVE-2021-32456

Credential disclosure via unencrypted web-panel authentication

Published May 17, 2021 · Updated Sep 17, 2024

Cleartext credential transmission in SITEL CAP/PRX 5.2.01 allows man-in-the-middle attackers to read web-panel passwords from HTTP traffic. The web panel performs legitimate-user authentication over unencrypted HTTP, placing access credentials in plaintext network packets. Exploitation requires access to the device's local network or the device user's computer; the documented consequence is disclosure of authentication passwords.
