IO-1020 Micro ELD: Download of Code Without Integrity Check

CVE-2024-28878 is a critical-severity download of code without integrity check vulnerability in IO-1020 Micro ELD from IOSiX, with a CVSS 3.1 base score of 9.6 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. The record lists version 360 as the first without the flaw, so updating IO-1020 Micro ELD to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

IO-1020 Micro ELD downloads source code or an executable from an adjacent location and executes the code without sufficiently verifying the origin or integrity of the code.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Download of Code Without Integrity Check

The product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code.

How developers prevent this class of flaw

  • Perform proper forward and reverse DNS lookups to detect DNS spoofing.
  • Encrypt the code with a reliable encryption scheme before transmitting.
  • Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
