LoadMaster: Insufficiently Protected Credentials

Published Updated By the CyberSecBulletin desk

CVE-2024-3543 is a high-severity insufficiently protected credentials vulnerability in LoadMaster from Progress Software, 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. The record lists versions 7.2.59.4, 7.2.54.10, 7.2.48.12 as the first without the flaw, so updating LoadMaster to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.28% 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

  1. Update LoadMaster to 7.2.59.4 or 7.2.54.10 or 7.2.48.12, whichever matches your release line, or a later version.
  2. Update loadmaster to 7.2.48.12 or 7.2.54.10 or 7.5.59.4, whichever matches your release line, 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

Use of reversible password encryption algorithm allows attackers to decrypt passwords. Sensitive information can be easily unencrypted by the attacker, stolen credentials can be used for arbitrary actions to corrupt the system.

The underlying weakness: Insufficiently Protected Credentials

The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.

How developers prevent this class of flaw

  • Use an appropriate security mechanism to protect the credentials.
  • Make appropriate use of cryptography to protect the credentials.
  • Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
