An exploitable denial of service vulnerability exists in the ENIP Request Path Data Segment functionality of Allen-Bradley Flex IO 1794-AENT/B. A specially crafted network request can cause a loss of communications with the device resulting in denial-of-service. An attacker can send a malicious packet to trigger this vulnerability.If the Simple Segment Sub-Type is supplied, the device treats the byte following as the Data Size in words. When this value represents a size greater than what remains in the packet data, the device enters a fault state where communication with the device is lost and a physical power cycle is required. Se presenta una vulnerabilidad de denegación de servicio explotable en la funcionalidad ENIP Request Path Data Segment de Allen-Bradley Flex IO 1794-AENT/B. • https://talosintelligence.com/vulnerability_reports/TALOS-2020-1007 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

Rockwell Automation Logix Designer Studio 5000 Versions 32.00, 32.01, and 32.02 vulnerable to an xml external entity (XXE) vulnerability, which may allow an attacker to view hostnames or other resources from the program. Rockwell Automation Logix Designer Studio 5000 Versiones 32.00, 32.01 y 32.02, es susceptible a una vulnerabilidad de tipo xml external entity (XXE), que puede permitir a un atacante visualizar nombres de host u otros recursos del programa This vulnerability allows remote attackers to disclose sensitive information on affected installations of Rockwell Automation Studio 5000. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of AML files. Due to the improper restriction of XML External Entity (XXE) references, a specially crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of the current process. • https://us-cert.cisa.gov/ics/advisories/icsa-20-191-02 • CWE-611: Improper Restriction of XML External Entity Reference •
