# Discovery Date: 2022-01-06
|
|
# Vendor Homepage: http://www.angusj.com/resourcehacker/
|
|
# Software Link : http://www.angusj.com/resourcehacker/
|
|
# Tested Version: 3.6.0.92

CVSS v3: 7.3

CVSS vector: CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H
|

CWE: CWE-119
|
|
|
|
Heap-based buffer overflow controlling the Structured Exception Handler
|
|
(SEH) records in Reseource Hacker v3.6.0.92, and possibly other versions,
|
|
may allow attackers to execute arbitrary code via a long file name argument.
|
|
|
|
Proof of concept:
|
|
|
|
Open ResHacker.exe from command line with a large string in Arguments, more
|
|
than 268 chars:
|
|
|
|
File 'C:\ResourceHacker36\ResHacker.exe'
|
|
Arguments
|
|
'Aa0Aa1Aa2Aa3Aa4Aa5Aa6Aa7Aa8Aa9Ab0Ab1Ab2Ab3Ab4Ab5Ab6Ab7Ab8Ab9Ac0Ac1Ac2Ac3Ac4Ac5Ac6Ac...'
|
|
|
|
SEH chain of main thread
|
|
Address SE handler

|
