    IBM's Apache-derived HTTP server is vulnerable to attack, although I know of no publicly available exploit code. At one point, it was claimed that the Chunked Encoding bug was only exploitable on some systems, but this has been shown to be untrue.
    
    IBM has issued a fix for the flaw.

    Subject: Apache Chunked Encoding Vulnerability on AIX (RS6000) 
    
    
    
    Hi All,
    
    I am currently pen-testing an AIX platform, which utilises Apache and IBM HTTP 
    server in order to communicate with a back-end AS400 enviornment.
    
    I have scanned the remote host with the eeye tool Retina - Apache Chunked 
    scanner V 1,0,3, which reports the host vulnerable.
    
    It would appear the tool attempts to exploit the vulnerability by attempting to 
    send a small request that makes a vulnerable server to become unresponsive.
    
    Would I be right to say that this vulnerability is not exploitable on an RS6000 
    platform, given the current exploits in the wild, and the eeye tool is again 
    producing false positives ????????
    
    Any help is very much appreciated.
    
    Thanks in advance.
