Cryptographic Weakness Leaves Web Apps Vulnerable

A couple of researchers developed what they are calling the Padding Oracle Exploit Tool to demonstrate the cryptographic weaknesses in web applications developed using Microsoft’s ASP.Net framework.  The vulnerability exists in the way web applications handle encrypted session cookies.  Attacks utilizing this weakness could allow a potential hacker to decrypt sniffed cookies or forge authentication tickets, among a number of other attacks.
The video below demonstrates the Padding Oracle Exploit Tool exploiting this vulnerability.

Critical Flash Vulnerability Is Under Attack

Adobe announced today a security advisory regarding a critical vulnerability that is already being exploited in the wild. The affected applications are:

  • Adobe Flash Player 10.1.82.76 and earlier versions for Windows, Macintosh, Linux, Solaris, and Adobe Flash Player 10.1.92.10 for Android
  • Adobe Reader 9.3.4 and earlier versions for Windows, Macintosh and UNIX
  • Adobe Acrobat 9.3.4 and earlier versions for Windows and Macintosh

[box type="warning"]A critical vulnerability exists in Adobe Flash Player 10.1.82.76 and earlier versions for Windows, Macintosh, Linux, Solaris, and Adobe Flash Player 10.1.92.10 for Android. This vulnerability also affects Adobe Reader 9.3.4 for Windows, Macintosh and UNIX, and Adobe Acrobat 9.3.4 and earlier versions for Windows and Macintosh. This vulnerability (CVE-2010-2884) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being actively exploited in the wild against Adobe Flash Player on Windows. Adobe is not aware of any attacks exploiting this vulnerability against Adobe Reader or Acrobat to date.

We are in the process of finalizing a fix for the issue and expect to provide an update for Adobe Flash Player for Windows, Macintosh, Linux, Solaris, and Android operating systems during the week of September 27, 2010. We expect to provide updates for Adobe Reader 9.3.4 for Windows, Macintosh and UNIX, and Adobe Acrobat 9.3.4 for Windows and Macintosh during the week of October 4, 2010.

Adobe actively shares information about this and other vulnerabilities with partners in the security community to enable them to quickly develop detection and quarantine methods to protect users until a patch is available. As always, Adobe recommends that users follow security best practices by keeping their anti-malware software and definitions up to date.
