SICK Media Server: Cleartext Transmission of Sensitive Information
CVE-2025-49194 is a high-severity cleartext transmission of sensitive information vulnerability in SICK Media Server from SICK, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected SICK Media Server versions: all versions. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.33% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of SICK Media Server you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on sick.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
The server supports authentication methods in which credentials are sent in plaintext over unencrypted channels. If an attacker were to intercept traffic between a client and this server, the credentials would be exposed.

The underlying weakness: Cleartext Transmission of Sensitive Information
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How developers prevent this class of flaw
- Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
- When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
- When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
