Published Updated By the CyberSecBulletin desk

CVE-2024-12011 is a high-severity buffer over-read vulnerability in 130.8005 from Zettler, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected 130.8005 versions: 12h. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.4% 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. Check which version of 130.8005 you run against the affected versions below, and install the vendor's latest release.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  3. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

A CWE-126 “Buffer Over-read” was discovered affecting the 130.8005 TCP/IP Gateway running firmware version 12h. The information disclosure can be triggered by leveraging a memory leak affecting the web server. A remote unauthenticated attacker can exploit this vulnerability in order to leak valid authentication tokens from the process memory associated to users currently logged to the system and bypass the authentication mechanism.

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

The underlying weakness: Buffer Over-read
