Python move-faqwiz.sh symlink
| python-movefaqwiz-symlink (45161) |  Medium Risk |
Description:
Python could allow a local attacker to launch a symlink attack. The move-faqwiz.sh script creates temporary files insecurely. A local attacker could exploit this vulnerability by creating a symbolic link from a temporary file to other various files on the system, which would allow the attacker to overwrite arbitrary files on the system with elevated privileges.
