VAR-202011-0742
Vulnerability from variot - Updated: 2023-12-18 12:27A heap overflow vulnerability exists within FactoryTalk Linx Version 6.11 and prior. This vulnerability could allow a remote, unauthenticated attacker to send malicious set attribute requests, which could result in the leaking of sensitive information. This information disclosure could lead to the bypass of address space layout randomization (ASLR). 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. 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. 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
