Severity:
=========
High
Details:
========
1.1
A local command injection vulnerability is detected in the official Trend Micro
DirectPass v1.5.0.1060 Software.
The vulnerability allows local low privileged system user accounts to inject
system specific commands or local
path requests to compromise the software.
The vulnerability is located in the direct-pass master password setup module of
the Trend Micro InstallWorkspace.exe file.
The master password module of the software allows users to review the included
password in the secound step for security
reason. The hidden protected master password will only be visible in the check
module when the customer is processing to
mouse-over onto the censored password field. When the software is processing to
display the hidden password in plain the
command/path injection will be executed out of the not parsed master password
context in in the field listing.
Exploitation of the vulnerability requires a low privilege system user account
with direct-pass access and low or medium
user interaction. Successful exploitation of the vulnerability results in
software and system process compromise or
execution of local system specific commands/path.
Vulnerable File(s):
[+] InstallWorkspace.exe
Vulnerable Module(s):
[+] Setup Master Password
Vulnerable Parameter(s):
[+] Master Password
Affected Module(s):
[+] Check Listing (Master Password)
1.2
A persistent input validation vulnerability is detected in the official Trend
Micro DirectPass v1.5.0.1060 Software.
The bug allows local attackers with low privileged system user account to
implement/inject malicious script code on
application side (persistent) of the software.
The persistent web vulnerability is located in the direct-pass check module
when processing to list a manipulated master password.
In step one injects a malicious iframe in the hidden fields as master password.
The inserted context will be saved and the execution
will be in the next step when processing to list the master password context in
the last check module. To bypass the validation the
and execute the injected script code the attacker needs to split (%20) the
input request.
Exploitation of the vulnerability requires medium user interaction and a low
privilege system user account with direct-pass.
Successful exploitation of the vulnerability can lead to persistent session
hijacking (customers), persistent phishing,
persistent external redirects to malware or scam and persistent web context
manipulation of the affected vulnerable module.
Vulnerable File(s):
[+] InstallWorkspace.exe
Vulnerable Module(s):
[+] Setup Master Password
Vulnerable Parameter(s):
[+] Master Password
Affected Module(s):
[+] Check Listing (Master Password)
1.3
A critical pointer vulnerability (DoS) is detected in the official Trend Micro
DirectPass v1.5.0.1060 Software.
The bug allows local attackers with low privileged system user account to crash
the software via pointer vulnerability.
The pointer vulnerability is also located in the direct-pass master password
listing section. Attackers can inject scripts with
loops to mouse-over multiple times the hidden password check listing of the
master password. The result is a stable cash down
of the InstallWorkspace.exe. The problem occurs in the libcef.dll
(1.1.0.1044)of the trend micro direct-pass software core.
Exploitation of the vulnerability requires medium user interaction and a low
privilege system user account with direct-pass.
Successful exploitation of the denial of service vulnerability can lead to a
software core crash and also stable software module hangups.
Vulnerable File(s):
[+] InstallWorkspace.exe
Vulnerable Library:
[+] libcef.dll (Dynamic Link Library)
Vulnerable Module(s):
[+] Check Listing (Master Password)
Vulnerable Parameter(s):
[+] Master Password
Proof of Concept:
=================
1.1
The code injection vulnerability can be exploited by local attackers with
privileged system user account and medium or high user interaction.
For demonstration or reproduce ...
PoC:
B%20>">../;'[COMMAND|PATH INJECT!]>
Example Path: C:\Users\BKM\TrendMicro DirectPass
Note: The bug allows attackers to request local restricted folders with the
system software privileges to manipulate software files and the
bound dynamic link libraries.
1.2
The persistent script code inject vulnerability can be exploited by local
attackers with privileged system user account and medium
or high user interaction. For demonstration or reproduce ...
PoC: (Input)
B%20>"<iframe src=a>[PERSISTENT SCRIPT CODE!]
Note: The master password is restricted to 20 chars per field on insert. The
execution of persistent injected frames works also with external source.
1.3
The pointer (DoS) vulnerability can be exploited by local attackers with
privileged system user account and low, medium or high user interaction.
For demonstration or reproduce ...
Path: C:\Downloadz\TrendMicro_DP_MUI_Download\Package\Share\UI
Dynamic Link Library: libcef.dll
PoC: (Input)
%20%000000---%000%20
Note: The string crashs the master password check review module and the
installworkspace.exe software process via null pointer (Dos) bug.
The reproduce of the vulnerability can result in a permanent denial of service
when the context is saved in the first instance and the save
has been canceled.
Critical Note: When i was checking the section i was thinking about how to use
the injected code in the section to get access to the stored password.
I was processing to load my debugger and attached it to the process when the
request was sucessful and saved the address.
After it i reproduced the same request with attached debugger and exploited the
issue in the local cloud software mask.
Then i was reviewing the changes and was able to use the injected frame test to
see the location of the memory in the debugger.
By processing to inject more and more context i was able to see were the
location of the password in the memory has been stored when the software
is processing to redisplay the saved temp password. Since today i have never
seen this kind of method in any book or paper but i am sure i will
soon write about the incident.
Solution:
=========
Both vulnerabilities can be patched by a secure parse or encode of the master
password listing in the master password check module of the software.
Filter and parse the master password and description security tip input fields.
For the denial of service issue is no solution available yet but the fixes will
prevent the manually exploitation of the issue.
Note: The update is available from the update-server since the 12th may but
trend micro says it was the 9th may.
On the 18th we downloaded again the main software direct-pass and tested the
core without an update and it was still vulnerable.
To fix the issue in the software an update from the update-server is required
after the install.
Risk:
=====
1.1
The security risk of the local command/path injection software vulnerability in
the directpass software core is estimated as high(-).
1.2
The security risk of the persistent scirpt code inject vulnerability is
estimated as medium(+).
1.3
The security risk of the pointer (DoS) software vulnerability is estimated as
medium(-).
