Basic Usage
msf > use auxiliary/scanner/http/httpdasm_directory_traversal
msf auxiliary(httpdasm_directory_traversal) > show targets
... a list of targets ...
msf auxiliary(httpdasm_directory_traversal) > set TARGET target-id
msf auxiliary(httpdasm_directory_traversal) > show options

- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
Knowledge Base
Description
This module exploits a directory traversal vulnerability to read files from a server running httpdasm v0.92.
Vulnerable Application
httpdasm 0.92
The vulnerability can be found in HTTPRqst.asm file.
The beginning of the ServeContent routine attempts to check file path with SafeFilePath:
1403 invoke SafeFilePath, __this
1404 .if (!eax) ;File is not safe
1405 mov m_dwCode, HTTP_STATUS_FORBIDDEN
1406 jmp doneHTTPGet
1407 .endif
1408 invoke ExtractFilename, __this
1409 .if (!eax)
1410 mov m_dwCode, HTTP_STATUS_URI_TOO_LONG ;max URI is 256 here
1411 jmp doneHTTPGe$
1412 .endif
The SafeFilePath checks for directory traversal with these possible values such as "..", "//", "\", ":", which is inadequate to prevent a traversal attack:
502 .if ((cx == '..') || (cx == '//') || (cl == '\') || (cl == ':'))
1503 return 0
1504 .endif
Verification Steps
- Start
