Remote Access Server (RAS): Cleartext Transmission of Sensitive Information

Published Updated By the CyberSecBulletin desk

CVE-2024-26155 is a high-severity cleartext transmission of sensitive information vulnerability in Remote Access Server (RAS) from ETIC Telecom, with a CVSS 3.1 base score of 8.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 4.5.0 as the first without the flaw, so updating Remote Access Server (RAS) to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.24% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Remote Access Server (RAS) to 4.5.0 or a later version.
  2. Update Remote Access Server Firmware to 4.5.0 or a later version.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

All versions of ETIC Telecom Remote Access Server (RAS) prior to 4.5.0 expose clear text credentials in the web portal. An attacker can access the ETIC RAS web portal and view the HTML code, which is configured to be hidden, thus allowing a connection to the ETIC RAS ssh server, which could enable an attacker to perform actions on the device.

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.
