Detailed Description |
| Business Impact: |
This vulnerability primarily affects endpoints, requires some user interaction (clicking malicious link), but allows an attacker to remotely execute code on the target system. Multiple research groups have published significant information on the issue, so constructing a working exploit would be fairly trivial. The growing list of affected applications and lack of patches for the applications (esp. Adobe PDF Viewer) along with the underlying vulnerability (Microsoft) also contribute to the severity of this issue. |

| Technical Description: |
Multiple applications, including Adobe Acrobat Reader, Skype, Mozilla Firefox, Thunderbird, Netscape Navigator, Microsoft Outlook, and Microsoft Outlook Express could allow a remote attacker to bypass cross-application restrictions and execute arbitrary commands on the system, caused by improper handling of multiple URIs, including the Mailto, nntp, news, snews, and telnet URI protocol handlers. By persuading a victim to visit a specially-crafted Web page that calls one of the vulnerable protocol handlers, a remote attacker could exploit this vulnerability to inject and execute arbitrary shell commands on the system. Note: XULRunner apps such as Joost and Democracy Player are also affected by this vulnerability. |
| Remediation: |
Some patches are available for this issue. See References for details. |
