  Red Hat Security Advisory 2011-1854-01

   » ‎ Packet Storm Security Advisories
  Red Hat Security Advisory 2011-1854-01 - The krb5-appl packages provide Kerberos-aware telnet, ftp, rcp, rsh, and rlogin clients and servers. Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third-party, the Key Distribution Center. A buffer overflow flaw was found in the MIT krb5 telnet daemon. A remote attacker who can access the telnet port of a target machine could use this flaw to execute arbitrary code as root. Note that the krb5 telnet daemon is not enabled by default in any version of Red Hat Enterprise Linux. In addition, the default firewall rules block remote access to the telnet port. This flaw does not affect the telnet daemon distributed in the telnet-server package.

  Linux BSD-derived Telnet Service Encyption Key ID Buffer Overflow

   » ‎ Packet Storm Security Exploits
  This Metasploit module exploits a buffer overflow in the encryption option handler of the Linux BSD-derived telnet service (inetutils or krb5-telnet). Most Linux distributions use NetKit-derived telnet daemons, so this flaw only applies to a small subset of Linux systems running telnetd.

  Hot to manually test telnet authentication bypass vulnerability?

   » ‎ remote-exploit & backtrack
  I am busy testing a system and Nessus reports that it is possible to exploit it and from the Nessus output it seems like Nessus was successful, see below. However, I cannot find any information anywhere on how to manually produce this vulnerability. Do not confuse it with the horde of other telnet vulnerabilities out there.
  
  I thought it would be as simple is some of the old telnet environment variable vulnerabilities e.g. telnet -l '-fbin' systemx.com but it does not seem to work, any ideas?
  
  
  Kerberos telnet Crafted Username Remote Authentication Bypass
  
  Synopsis:
  It is possible to log into the remote system using telnet without supplying any credentials
  
  Description:
  The remote version of kerberos telnet does not sanitize the user-supplied 'USER' environement variable. By supplying a specially malformed USER environment variable, an attacker may force the remote telnet server to believe that the user has already authenticated.
  
  Risk factor:
  High
  
  CVSS Base Score:7.6
  CVSS2#AV:N/AC:H/Au:N/C:C/I:C/A:C
  
  Solution:
  Apply the patch below or contact your vendor for a patch :
  
  Plugin output:
  It was possible to log in and execute "id" : ];root@systemx:~ [root@systemx ~]# uid=
  
  Plugin ID:
  24998
  
  CVE:
  CVE-2007-0956
  
  BID:
  23281
  
  Other references:
  OSVDB:34106

  XHydra

   » ‎ remote-exploit & backtrack
  ciao ho visto il video su youtube dell uso di Xhydra e ho fatto delle prove. tuttavia ho molte domande da chiedere.
  
  1) che ip devo utilizzare all'inizio? io ho 2 pc collegati al router, ho usato l'ip dell'altro
  2) tra le varie porte aperte la 23 di telnet che c è sul video non c'è...quindi come si va avanti?
  
  io ho provato con una porta che mi diceva aperta così:
  numero e poi, open http Microsoft HTTPAPI httpd 1.0 (SSDP/UPnP
  quindi in xhydra invece che protocol telnet ho usato http-get
  poi non avendo il file worldlist.txt e nn sapendo dove trovarlo ne ho creato uno contenente solo la vera password del router (x provare)
  ho impostato tutto e ha sembrato funzionare (xò nn ne sono sicuro)
  cmq a questo punto nel video lui digita telnet indirizzo ip e la porta, ma se io non ho usato telnet che devo fare?
  come vado avanti a questo punto?
  scusatemi, magari è una cosa facilissima...ma sono alle prime armi con backtrack.
  
  se qualcuno mi spiegasse meglio ne sarei grato.
  
  ciao ciao
