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.

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.

### Impact XML parsing performed by the UcumEssenceService is vulnerable to XML external entity injections. A processed XML file with a malicious DTD tag could produce XML containing data from the host system. This impacts use cases where ucum is being used to within a host where external clients can submit XML. ### Patches Release 1.0.9 of ucum fixes this vulnerability ### Workarounds Ensure that the source xml for instantiating UcumEssenceService is trusted. ### References * https://cwe.mitre.org/data/definitions/611.html * https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html#jaxp-documentbuilderfactory-saxparserfactory-and-dom4j

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.

### Impact When calling the extended toHTMLEx method, it is possible to execute arbitrary JavaScript code. ### Patches The supplied patch resolves this vulnerability for SimpleXLSX. Use 1.1.12 ### Workarounds Don't use direct publication via toHTMLEx *** This vulnerability was discovered by Aleksey Solovev (Positive Technologies)

### Summary _Short summary of the problem. Make the impact and severity as clear as possible. For example: An unsafe deserialization vulnerability allows any unauthenticated user to execute arbitrary code on the server._ There is a potential XXE(XML External Entity Injection) vulnerability when http4k handling malicious XML contents within requests, which might allow attackers to read local sensitive information on server, trigger Server-side Request Forgery and even execute code under some circumstances. ### Details _Give all details on the vulnerability. Pointing to the incriminated source code is very helpful for the maintainer._ https://github.com/http4k/http4k/blob/25696dff2d90206cc1da42f42a1a8dbcdbcdf18c/core/format/xml/src/main/kotlin/org/http4k/format/Xml.kt#L42-L46 XML contents is parsed with DocumentBuilder without security settings on or external entity enabled ### PoC _Complete instructions, including specific configuration details, to reproduce the vulnerability._ #### ...

The ABB BMS/BAS controller suffers from an unauthenticated blind OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the 'portValue' HTTP GET parameter called by obtainPorts.php script.

The obtainPorts.php script is accessible without authentication, allowing unauthorized users to retrieve and manipulate configuration parameters. This includes the ability to modify critical settings such as port values, potentially disrupting system functionality or enabling further exploitation.
