The ABB Cylon Aspect BMS/BAS controller allows users to bypass authentication by setting the 'content' POST parameter. This enables an attacker to inject arbitrary configuration overrides, potentially leading to unauthorized changes and compromising system integrity. The vulnerability can be exploited to update the /usr/local/aam/etc/override.properties file. This file contains critical configuration overrides such as enabling overrides (Override.enabled=true) and setting specific properties like debug.level=1. The runjava.VARIANT* script then sources this file during execution, applying the overrides when the system reboots or the application restarts. This allows attackers to manipulate critical system settings, potentially causing performance degradation, introducing security risks, or resulting in a denial of service scenario.

IntroductionIn a previous article, I demonstrated how to configure the Automatic Certificate Management Environment (ACME) feature included in the Identity Management (IdM) Dogtag Certificate Authority (CA). Specifically, I covered installation of IdM with random serial numbers, and how to enable the ACME service and expired certificate pruning. This article explains the management of ACME (currently a technology preview) with IdM and Red Hat Enterprise Linux (RHEL) clients.Currently, mod_md is the only ACME client implementation completely supported and provided by Red Hat. For this article,

Defenders running the Cleo managed file transfer are urged to be on the lookout for the Cleopatra backdoor and other indicators of an ongoing ransomware campaign, as patching details remain foggy, and no CVE has been issued.

An authenticated access vulnerability in the aspectMemory.php script of ABB Cylon Aspect BMS/BAS controllers allows attackers to set arbitrary values for Java heap memory parameters (HEAPMIN and HEAPMAX). This configuration is written to /usr/local/aam/etc/javamem. The absence of input validation can lead to system performance degradation, Denial-of-Service (DoS) conditions, and crashes of critical Java applications.
