Nearly two-dozen different laptop models sold by Hewlett-Packard ship with software plagued with multiple zero-day vulnerabilities, security researchers said Wednesday.
The bugs are in an ActiveX control included with the HP Info Center software preinstalled on both HP- and Compaq-branded laptops running Windows 2000, XP, Server 2003 and Vista, Symantec said in a note to clients of its DeepSight threat network. Info Center is a part of HP's Quick Launch Buttons application, which gives users one-click access to information and configuration details on the portables.
"One of its ActiveX controls deployed by default by the vendor has three insecure methods that allow a malicious person to target the HP notebook machines for a remote code execution- and remote registry manipulation-based attacks," said a researcher using the alias "porkythepig" in posts to both milw0rm.com and the Bugtraq security mailing list.
The posts spelled out the vulnerabilities and included proof-of-concept exploit code.
Symantec recommended that users set the "kill bit" on the ActiveX control until HP produces a patch; that process, however, requires editing the Windows registry, a daunting chore for most. A less effective defense would be to disable Active Scripting in Internet Explorer, Symantec added in the note, since "the primary way to exploit this vulnerability is via a malicious Web page."
Although porkythepig claimed that the defective ActiveX control has shipped with "almost every HP laptop model for [the past] few years," he claimed that 23 different notebooks had been confirmed as running the flawed control. The list included the HP 510 and 530; the Compaq 2710, 2510, 6120, 6220, 6230, 6325, 6510, 6715, 6910, 7300, 8220, 8230, 8440, 8510, 8710 and 9440; and the NC, NW and NX series notebooks.
The hacker also took a shot at HP in the messages on milw0rm.com and Bugtraq. "I think the company so deeply involved in security software patents war should take a bigger care about the users' security than taking profits from the rights to the invention of the circle," said porkythepig. "After all, what are the security software patents worth if it is the user who has the final word about their own software security?"
It was unclear what "patents war" porkythepig referred to, but HP recently settled with Web application security vendor Cenzic to cross-license multiple patents that had been at the heart of two lawsuits filed by SPI Dynamics, a security testing tools developer acquired by HP in June. The settlement was announced by the two companies Oct. 1, and the lawsuits were immediately dropped.
HP was not available for comment on the ActiveX bugs disclosed by porkythepig.
