CVE-2025-48925Known exploitationPublic exploitNetwork attack vector

Account impersonation via replayable client-side password hashes

Published May 28, 2025 · Updated Jul 1, 2025

Authentication bypass in the TeleMessage service through 2025-05-05 allows remote attackers to assume user identities using captured password hashes. The service trusts an MD5 hash produced by the client as the authentication credential, so the original password is unnecessary. Exploitation requires obtaining a user's hash, after which replay permits access as that user; no broader impact is established for this flaw.
