Description
This module attempts to gain root privileges on RHEL systems with a vulnerable version of Automatic Bug Reporting Tool (ABRT) configured as the crash handler.
`sosreport` uses an insecure temporary directory, allowing local users to write to arbitrary files (CVE-2015-5287). This module uses a symlink attack on `/var/tmp/abrt/cc-*$pid/` to overwrite the `modprobe` path in `/proc/sys/kernel/modprobe`, resulting in root privileges.
Waiting for `sosreport` could take a few minutes.
This module has been tested successfully on:
abrt 2.1.11-12.el7 on RHEL 7.0 x86_64; and abrt 2.1.11-19.el7 on RHEL 7.1 x86_64.
