SecHard: Cleartext Transmission of Sensitive Information

Published Updated By the CyberSecBulletin desk

CVE-2025-2311 is a critical-severity cleartext transmission of sensitive information vulnerability in SecHard from SecHard Information Technologies, with a CVSS 3.1 base score of 9.0 out of 10. It can be exploited from the same local network by an attacker with a low-privileged account, without any action from a user. The record lists version 3.3.0.20220411 as the first without the flaw, so updating SecHard to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.17% chance of exploitation within 30 days, which is low compared with other CVEs.

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.
