Vulnerability:
|
|
Jerome Athias has discovered a vulnerability in My_Gallery plugin for
|
|
e107, which can be exploited by malicious people to disclose sensitive
|
|
information.
|
|
|
|
The vulnerability is caused due to an input validation error in
|
|
dload.php when processing arguments passed to the "file" parameter. This
|
|
can be exploited to download arbitrary files from the affected system.
|
|
|
|
The vulnerability is confirmed in version 2.3. Other versions may also
|
|
be affected.
|
|
|
|
Solution:
|
|
Edit the source code to ensure that input is properly validated.
