Discussion

Mon 'alert.d/test.alert' Insecure Temporary File Creation Vulnerability

The 'mon' tool creates temporary files in an insecure manner.

An attacker with local access could potentially exploit this issue to perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application.

Successfully mounting a symlink attack may allow the attacker to delete or corrupt sensitive files, which may result in a denial of service. Other attacks may also be possible.
