 # Alcatel-Lucent Omnivista 4760/8770 RCE 0day
 ### Tldr
  * *4760* suffers an unauthenticated remote code execution as SYSTEM. No special configuration is required
- * *8770* and *4760* both suffer a remote administrative password dislclosure. No special configuration required
+ * *8770* and *4760* both suffer a remote administrative password disclosure. No special configuration required
  * *8770* suffer an authenticated remote code execution vulnerability. When chained with the disclosure vulnerability, it becomes an unauth RCE. In this case access to the port 389 and a directory license are required

As shown in the previous section, there wasn't any known vulnerability in this component. I wasn't unable to find any useful vulnerability without the source code, but only a few hints:

 ## Unpacking it
-Since the 4760 is an ancient product I fired up a Windows XP virtual machine and tried installing it. Like it happens most of the time with enterprise software, the installation failed and neither the main services were set up properly nor any PHP files was extracted. Part of the files were packed with the ancient ACE file format, probbly with some custom modifications, and even binwalk couldn't do much.
-When i started getting frustrated with all this ancient enteprisise crap, i finally found the PHP files inside a CAB archive.

So by just starting a session and getting the respective session file it is possible to get the credentials.
