VAR-202011-0741
Vulnerability from variot - Updated: 2023-12-18 12:27A flaw exists in the Ingress/Egress checks routine of FactoryTalk Linx Version 6.11 and prior. This vulnerability could allow a remote, unauthenticated attacker to specifically craft a malicious packet resulting in a denial-of-service condition on the device. Rockwell Automation Provided by the company FactoryTalk Linx Is vulnerable to several vulnerabilities: ‥ * Improper input confirmation (CWE-20) - CVE-2020-27253 ‥ * Heap-based buffer overflow (CWE-122) - CVE-2020-27251 ‥ * Heap-based buffer overflow (CWE-122) - CVE-2020-27255The expected impact depends on each vulnerability, but it may be affected as follows. * FactoryTalk Linx There is a defect in the input / output check routine of the service, and a malicious packet is sent by a remote third party, which interferes with service operation. (DoS) Be in a state - CVE-2020-27253 * A remote third party sends a request with a malicious value for a parameter that specifies a port range and executes arbitrary code. - CVE-2020-27251 * A malicious attribute setting request is sent by a remote third party to steal sensitive information. Also, due to this information theft, ASLR ( Address space layout randomization ) Is bypassed - CVE-2020-27255. FactoryTalk Linx is a FactoryTalk Live Data server and communication service designed to transfer control system information from Allen-Bradley control products to Rockwell Automation FactoryTalk software product portfolio and Studio5000 design software.
FactoryTalk Linx 6.11 and earlier versions of Ingress/Egress check routines have improper input validation vulnerabilities. Rockwell Automation FactoryTalk Linx is a set of industrial communication solutions from Rockwell Automation, USA. This product is mainly used for communication between small applications and large automation systems
