Cookie information is corrupt

Hi,
I get the warning message "Cookie information is corrupt" on one of our routers (Cisco 827).
It boots up in rommon and I am not able to boot up IOS. I have tried to install a new image using TFTP, but I get the same error message when I try the tftpdnld command from rommon.
Has anyone got any ideas how to fix this? Any help would be very appreciated!
Regards,
Harald

The IOS version that is running on the router is 12.3.6c. I have sucessfully upgraded the ROMMON to the latest version, but that did not help.
Our test ADSL connection (using this router) just suddenly stopped working on Monday. When I logged into the router I had the error message.
I have tried searching for the error message on CCO and the Internet, but I cannot find any soulutions.
Thanks again for your help!
Regards,
Harald

WARNING: Cookie information is corrupt

Followed FN - 63170.
After C3200_RM_ALT.srec.124-15r.T1 is installed I still get the cookie warning and when I do a show cookie it still shows all 00 00 00's.
Can't get to the next step, TFTP or xmodem the new IOS image. It haults at rommon everytime. When I attempt to TFTP or xmodem the new image "WARNING: Cookie information is corrupt" scrolls down the screen and when complete I get a "Download failed, invalid image"...something like that.
Now I get more error messages...

Any suggestions????

Yes I did. It turns out once the cookie is corrupt there is no way for a customer of Cisco to re-create the cookie. It holds information (hardware information) that is necessary for the IOS upgrade. It will transfer to flash but when complete it will not verify correctly and will fail the download.
This link explains it all. The bootstrap upgrade is only to prevent the cookie from being corrupt. Once it is you must RMA with Cisco.

Cookie information is Corrupted ( Cisco 837 )

I have a Cisco 837 Router and its Cookie information in EPROM is deleted. I want know that how to enter cookie information in this Router.Kindly reply ASAP.

Mujeeb

verify if the "Chassis MAC Address" has been programed into the EEPROM cookie by issuing the IOS command show diag. Refer to the example below for appropriate output modifiers. Output modifiers are case sensitive.
Example of router with a properly programmed MAC address:
RouterRouter#show diag | include Chassis MAC Address
Chassis MAC Address: 000d.29f8.64d0

Nessus report says: Apache HTTP Server httpOnly Cookie Information Disclosu

Hi all,
Security area ran a Nessus script in the network and it found a known vulnerability over Oracle HTTP Server. Nessus gives a recomendation and I think is not the best recomendation because Oracle Application Server 10g R2 doesn't supports Apache 2.2.22 (only 1.3).
The question is:
What other action plan can I execute in order to solve the vulnerability issue?
This is the Nessus report:
Apache HTTP Server httpOnly Cookie Information Disclosure
Synopsis:
The web server running on the remote host has an information disclosure vulnerability.
Description:
The version of Apache HTTP Server running on the remote host has an information disclosure vulnerability. Sending a request with HTTP headers long enough to exceed the server limit causes the web server to respond with an HTTP 400. By default, the offending HTTP header and value are displayed on the 400 error page. When used in conjunction with other attacks (e.g., cross-site scripting), this could result in the compromise of httpOnly cookies.
Risk factor:
Medium

How can i hack a session if i have the cookie information?

Hi All,
I am in the process of testing an application in my organization for the security vulnerabilities.
I saw a tutorial where an attacker launches an attack and get the cookie details of the victim. Now what step is next the hacker will do to launch a successful attack, this is what i want to know.
Can anyone tell me how can i hack/replicate a session of another user (who is logged in to X application) and i have the cookie details of this logged in user?
Thanks in advance.
-Abhi.

Well i am just a white hat with no intentions of stealing information at all. I am just a beginner in the field of security testing.
Also about abhi, i am not the only abhi there may be a millions of abhi.
I watched a video on XSS injection where i saw that the hacker is able to figure out the session information of the victim. The link is as below:
http://www.virtualforge.de/vmovie/xss_lesson_1/xss_selling_platform_v1.0.html
After watching this video i thought that how a hacker may be able to exploit the session information of some other user. That is why i took the path of posting in forums.
I just needed to know if i am able to find this security vulnerability in one of the applications developed in my organization. Further i would like to report this vulnerability if it existed.
Thanks,
Abhi

How to fix this problem? What is the command for restoring these cookies back?

Hello,
The cookie contains vital information about your router including some very specific hardware settings, base MAC address and other data. Unfortunately, there is no command to replace it automatically, rather it has to be refilled with sensible data again.
It would be the best to find another working 1711 router and take its cookie value as an template. The MAC address would need to be located in the cookie and replaced with new unique value and then restored into the failed router. There is a procedure to do it from the ROMMON but I would rather not talk about it right now as it would be possible to "brick" your router completely. However, please do try to obtain the cookie from another working 1711 router. WIthout it, it may be impossible to recover your router.
Best regards,
Peter

Fixing an 827 with cookie corruption issues

Hi All,
I know there are other threads about this issue, but I cant figure this out.
We have 15 to 20 Cisco 827 routers with corrupt cookies (reading as all 0's).
I know how to log into priv mode, and know about entering the cookie details.
What I cant figure out, is how to take the cookie from one of our working 827's as seen here:
01 01 00 b0 c2 8d 42 fc 3e 00 01 ff 01 ff 00 00
00 00 00 00 00 00 00 00 4a 41 44 05 51 30 34 42
42 07 01 00 00 00 00 00 00 ff ff ff 50 06 49 11
ec 07 ff ff ff ff ff ff ff ff ff ff ff ff ff ff
ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
and use it to answer the questions on the non functional 827 when re-entering its cookie data.
I tried to enter it value for value, but the end result was the cookie looks different (some values missing, in the wrong place).
If someone could break down the above cookie into answers for the cookie build questions on a corrupt cookie router.
Cheers.

Could you explain how you did this?
I have a 1711 with the same problem.
I have at least 10 extra 1711's that I can get the cookie information off of but I'm now sure how to translate it.

ICal Alarm: None - Corrupted Information

When I'm creating new iCal events and go to set an Alarm, I'm now seeing the first entry in my list of previous options:
None - Corrupted Information
!http://img.skitch.com/20100107-jucxgwdwhyt21qdu11nk6rd284.png!
It appears others have seen this problem before - which is [documented in this thread|http://discussions.apple.com/thread.jspa?threadID=1983720] - but without resolution.
I happy that the system recognizes that the information is corrupted but I wish I knew how to resolve the the corruption.
Anybody know what I can do to clean this up?
Thanks!

Try this:
quit iCal
in the Library/Preferences in your home folder locate com.apple.iCal.plist
duplicate it in case something breaks
double-click com.apple.iCal.plist
click the black triangle beside root and scroll down to PersistentMenu-lastUsedAlarms
click the black triangle beside PersistentMenu-lastUsedAlarms
select item 0 under PersistentMenu-lastUsedAlarms and click Delete
File/Save

Firefox randomly reset it's self to deafault mode (but retained bookmarks), now won't retain cookies after closing firefox even though it's set to.

I was using Firefox last week and all of a sudden it crashed, when I started it back up again everything had been set back to factory default (but it kept my bookmarks). From then on it has refused to save cookies, I've been all through settings and everything is the way it should be. I have no add-ons that mess with cookies. I have no user.js file messing with anything. I've tried resetting firefox which did nothing, and I've completely uninstalled and reinstalled firefox. Nothing seems to fix the problem, every single time I close firefox or restart my computer I end up having to sign into every single website I go to....what gives?

If clearing cookies doesn't work then it is possible that the <i>cookies.sqlite</i> file that stores the cookies is corrupted.
Rename (or delete) <b>cookies.sqlite</b> (cookies.sqlite.old) and delete other present cookies files like <b>cookies.sqlite-journal</b> in the Firefox profile folder in case the file cookies.sqlite got corrupted.

You can use this button to go to the Firefox profile folder:

How to set a cookie in the browser from an html page called via an Iview

How to set a cookie in the browser from an html page called via an Iview
Hello all,
I have an issue which is causing problems. I have a snap survey (html form with submit and cookie setting) which is embedded in a url iview.
Although the submit and the form work fine, the portal will not allow the cookie to be set it seems.
Is there a way to allow cookies to be set from an embedded page in a url iview??
You will make my day if you know!
System: EP7 SP13
Kind regards

Hi,
Check this:
http://www.oracle.com/technology/products/ias/portal/html/same_cookie_domain_with_pdkv2.html
Cookie Basics
Web browsers have built in rules for receiving and sending cookies. When a browser makes a request to a web server and the web server returns cookies with the response, the browser will only accept a cookie if the domain associated with the cookie matches that of the original request. Similarly, when a browser makes a subsequent request, it will only send those cookies whose domain matches that of the target web server.
These rules are designed to ensure that information encoded in cookies is only "seen" by the web server(s) that the originator of the cookie intended. These rules also ensure that the cookie cannot be corrupted or imitated by another server. By default, the domain associated with a cookie exactly matches that of the server that created it. However, it is possible to modify the domain at the time the cookie is created. Relaxing the cookie domain increases the scope of the cookie's visibility making it available to a wider "audience" of web servers.
For example, if a cookie is created by a.us.oracle.com, it's domain will usually be set to a.us.oracle.com. This means that the browser will only send the cookie to a.us.oracle.com. It will never send it to any other servers. However, if at the time of creation, the domain of the cookie is set to .us.oracle.com, the browser will send the cookie to any server whose domain falls within .us.oracle.com. such as portal.us.oracle.com, provider.us.oracle.com, app.us.oracle.com etc

Can't enable cookies

I keep getting informed by Google+ that I need to enable cookies to log in, but I HAVE cookies enabled in all browsers.
I checked my Firefox folder, but could not find a profile folder anywhere to check if cookies.sqlt was corrupted.
HOW MANY TIMES DO I HAVE TO RESET FIREFOX TO ITS DEFAULT SETTINGS AND AFFIRM THAT COOKIES ARE ENABLED BEFORE GOOGLE WILL ACCEPT THIS????
This problem just started today, and has never been an issue before, but it is IMPOSSIBLE to contact Google about any form of technical support, and the few methods available require you to log into your account!!

Also, this same stupidity is happening no matter what browser I use!!
