CVE-2024-1212Exploited in the wildNVD status: Analyzed

Progress Kemp LoadMaster OS Command Injection

Published Updated By the CyberSecBulletin desk

CVE-2024-1212 is a critical-severity improper neutralization of special elements used in an OS command vulnerability in LoadMaster from Progress Software, with a CVSS 3.1 base score of 9.8 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 7.2.48.10, 7.2.54.8, 7.2.59.2 as the first without the flaw, so updating LoadMaster to one of those releases or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on November 18, 2024, which means attacks have been observed in the wild.

Patch now

Attackers are already exploiting this vulnerability, according to CISA.

What to do

  1. Update LoadMaster to 7.2.48.10 or 7.2.54.8 or 7.2.59.2, whichever matches your release line, or a later version.
  2. Update loadmaster to 7.2.48.10 or 7.2.54.8 or 7.2.59.2, whichever matches your release line, or a later version.
  3. CISA's required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
