CVE-2020-37221
HighSummary
Atomic Alarm Clock 6.3 contains a stack overflow vulnerability that allows local attackers to execute arbitrary code by supplying a malicious string to the display name textbox in the Time Zones Clock configuration.
Risk Assessment
Attackers can craft a buffer with structured exception handling overwrite and encoded shellcode to bypass SafeSEH protections and execute arbitrary commands with application privileges.
Recommendation
It is recommended to update to the latest version of Atomic Alarm Clock to eliminate this vulnerability and to monitor systems for potential attack attempts.
