1.    A critical vulnerability discovered in few LaserJet Pro printers that could give remote attackers access to sensitive data. The latest breach expose by Germany security expert, Christoph von Wittich.In brief points below :

-   HP LaserJet Professional printers contain a telnet debug shell which could allow a remote attacker to gain unauthorized access to data.

-   Christoph von Wittich,the guy detected the vulnerability during a routine network scan of his company's corporate network.

-   Vulnerability could also be used for a denial-of-service attack.

-   As long as the printer is not connected to the Internet, this vulnerability should not cause much trouble for the end user,".

2.    Now for HP something like this is not new....even in past about 2 years back in dec 2011,a vulnerabilty was discovered wherein "Print of one malicious document can expose your whole LAN".

3.    In-fact I discussed a past case at Feb 2012 last year here....3 months after that happened.HP seems to be busy with printing only....high time they start focusing serious work on security aspects too!!!!
