Linux authencesn Cryptographic Template Copy Fail Privilege Escalation Exploit

This module uses an incorrect 'in-place operation' vulnerability in the Linux kernel's algif_aead cryptographic algorithm interface by abusing the authencesn AEAD wrapper to deploy a network agent. The vulnerability will overwrite kernel's cached pages of a given SUID file. The module will upload a trigger binary for the vulnerability in the temporary directory given in the TMP_DIR parameter. If no parameter is provided, the module will use "/tmp" as the default value. The binary SUID file given in the TARGET_SUID_BINARY parameter will be used for the attack. If no parameter is provided, the module will use "/usr/bin/su" as the default value. Once the attack is complete a new Core Impact agent will be deployed in the target system that will run with root user privileges. Finally, the module will use the "sysctl" command to restore the cache.
