EUVDB-ID: #VU49159
Risk: Medium
CVSSv3.1: 6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2020-5807
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. An unauthenticated remote attacker can send data to RsvcHost.exe listening on TCP port 5241 to add entries in the FactoryTalk Diagnostics event log. A local user can use the FactoryTalk Diagnostics Viewer (FTDiagViewer.exe) to view the log. The attacker can specify long fields in the log entry, which can cause an unhandled exception by wcscpy_s() in FTDiagnosticsViewer.dll loaded in FTDiagViewer.exe, resulting in process termination.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
