CVE-2020-10377Network attack vector

Unauthenticated credential disclosure

Published Apr 17, 2020 · Updated Aug 4, 2024

Weak encryption in Mitel MiVoice Connect Client before 214.100.1214.0 allows remote attackers to obtain user credentials and access the system. Mitel has not disclosed the affected cipher, credential-storage locus, or operation that exposes the credentials. Exploitation requires no authentication but is constrained to systems configured for site-based security, and the reported consequence is account compromise.
