CVE-2025-48925 Details
Description
The TeleMessage service through 2025-05-05 relies on the client side (e.g., the TM SGNL app) to do MD5 hashing, and then accepts the hash as the authentication credential.
A vulnerability exists in the TeleMessage service, specifically in the TM SGNL application, which is a clone of Signal. The issue arises because the application relies on client-side MD5 hashing for authentication credentials. This flaw has been exploited in the wild, allowing unauthorized access to user accounts and sensitive data such as plaintext chat logs and encryption keys. The vulnerability is rooted in the use of an outdated and insecure hashing algorithm, combined with a misconfiguration that exposed sensitive information on the server.
