ASA Fails to parse certificates

-

Last night I was trying to get a VeriSign issued SSL certificate installed on my ASA using Cisco ASDM 6.2. I installed the Intermediate CA and the CA certificates all installed. I then imported the SSL certificate into the “Configuration -> Device Management -> Manage Certificates -> Identity Certificates” but it did not seem to work. I kept getting an error “Failed to parse or verify imported certificate”. The certificate was in the .p7b form. Changing the format of the certificate to X.509 Base64 Encoded format resulted in acceptance of the certificate.
I sincerely hope that Cisco alters its error messages to accurately reflect that .p7b is not a format supported by them.

Update: This link has the information on how to install SSL certificates on ASA:

Using Certificates with cURL

-

The problem: Using Digital Certificates issued by a Certification Authority (CA) with curl.

The situation: I have a .cer (Digital Certificate) file, .pfx (Personal Information Exchange file i.e., the private key for the certificate). I cannot use either of these to authenticate to the web service as curl would not accept these formats.

The solution:
1) Convert it into PEM format (X.509 certificate) using openssl.
openssl pkcs12 -in abcd.pfx -out abcd.pem
Enter a passphrase and a password.
2) Still you cannot use this with curl because you’d get a few errors.
3) Convert this PEM certificate into three different certificates for the client, the private key and the certification authority certificate.
openssl pkcs12 -in abcd.pfx -out ca.pem -cacerts -nokeys
openssl pkcs12 -in abcd.pfx -out client.pem -clcerts -nokeys
openssl pkcs12 -in abcd.pfx -out key.pem -nocerts
4) Use the following command:
curl -k https://www.thesitetoauthenticate.com/test -v –key key.pem –cacert ca.pem –cert client.pem:

This stuff is also mentioned on curl forum at http://curl.haxx.se/mail/archive-2005-09/0138.html

SSL v2.0 on Internet Explorer

-
Now that Firefox 2.0 does not have option to enable SSL v2.0, there’s one way it can still be activated in Internet Explorer. Goto Tools -> Internet Options -> Advanced as shown in the screenshot and uncheck all other ciphers except SSL 2.0 and you should be able to check if a particular website supports SSL v2.0.

Clubhack 2008

-

Jay Kelath and I will be presenting at ClubHack 2008. Our topic is “Snake in the Eagle’s Shadow: Blind SQL Injection” and it is about using Blind SQL Injection on Oracle, MSSQL (and possibly MySQL) to get content of remote databases and also using out of band mechanisms on Oracle database and blind sql injection to pilfer database information.
I’ve also written up a tool that I’ll be presenting with Jay to show how to exploit blind SQL injection to remotely download files. The technique I’m presenting is different from the time delay techniques as have been presented in the past using the waitfor delay statements. Traditionally, using the waitfor delay statement one can download database contents as was shown using tools such as Absinthe, SQLBrute, Blind SQL Brute Forcer. I just try to automate the “virtual” file downloading using BULK insert on MSSQL Server and download files. To do this you do not need any firewall allowances. The technique I use is if you can “infer” every byte of a file then you don’t need to download the file using a TCP connection, you can re-create the file yourself (you already know every byte of the file). The only limitation being that the data rates are pretty slow using this technique. However, since you do not rely on time delays it’s still faster than time delay techniques.
