New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 6.7
SynopsisA programmable logic controller (PLC) runtime on the remote host is affected by multiple vulnerabilities.
DescriptionThe 3S CODESYS Runtime environment running on the remote host is affected by multiple vulnerabilities :
- A memory corruption vulnerability exists in the CODESYS V3 runtime system. An unauthenticated, remote attacker can exploit this issue, via a specially crafted message, to cause a denial-of-service condition in the runtime. (CVE-2019-5105)
- A heap-based buffer overflow condition exists in the CODESYS V3 runtime component CmpWebServerHandlerV3 due to improper validation of user-supplied data. An unauthenticated, remote attacker can exploit this issue , via a series of specially crafted messages, to cause a denial of service condition or the execution of arbitrary code. (CVE-2020-10245)
Note that Nessus has not tested for the issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade CODESYS V3 Runtime to version 184.108.40.206 or higher.
