(Debian Issues Fix) Analog Web Log File Analysis Tool Allows Cross-Site Scripting Attacks
|
Date: Mar 28 2002
|
Impact: Disclosure of authentication information, Execution of arbitrary code via network
|
Fix Available: Yes
Vendor Confirmed: Yes
|
Version(s): prior to 5.22
|
Description: A vulnerability was reported in 'analog', a log file analysis tool. A remote user can conduct cross-site scripting attacks against analog users.
A remote user can reportedly insert arbitrary strings into any web server logfile so that, when those strings are subsequently analyzed
by analog, the strings will appear in the web-based analog report. This allows a remote user to inject arbitrary Javascript code
into an analog report. When the report is read by the target (victim) user, the code will be executed by the target user's browser.
The code will appear to originate from the site running analog and will run in the security context of that site. As a result,
the code can access the target user's cookies and other data associated with the site running analog.
Yuji Takahashi reportedly
discovered the bug.
|
Impact: A remote user can cause arbitrary javascript to be executed on another user's browser to steal the other user's cookies associated with a site running analog.
|
Solution: The vendor has released a fix for Debian GNU/Linux 2.2 alias potato:

Package : analog
Vulnerability : cross-site scripting
Problem-Type : remote
Debian-specific: no
Yuji Takahashi discovered a bug in analog which allows a cross-site
scripting type attack. It is easy for an attacker to insert arbitrary
strings into any web server logfile. If these strings are then
analysed by analog, they can appear in the report. By this means an
attacker can introduce arbitrary Javascript code, for example, into an
analog report produced by someone else and read by a third person.
Analog already attempted to encode unsafe characters to avoid this
type of attack, but the conversion was incomplete.
This problem has been fixed in the upstream version 5.22 of analog.
Unfortunately patching the old version of analog in the stable
distribution of Debian instead is a very large job that defeats us.
We recommend that you upgrade your analog package immediately.
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
If you are using the apt-get package manager, use the line for
sources.list as given below:
apt-get update
will update the internal database
apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.
