The vulnerability exists in the configuration daemon's time synchronization handler, which is responsible for setting the system time-zone. When processing time-zone configuration updates, the daemon constructs a shell command by concatenating user-supplied input without any sanitization or validation.\n\n## Affected\n\n- `coretec_5 >= 3.0.0 <= 5.0.0`\n- `coretec_4 >= 3.0.0 <= 3.4.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":42.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
