[-] Vulnerability Description:
|
||||
|
||||
User input passed through the "data[extension]" and "data[filedata]" parameters to
|
||||
the "ajax/api/user/updateAvatar" endpoint is not properly validated before being used
|
||||
to update users' avatars. This can be exploited to inject and execute arbitrary PHP code.
|
||||
Successful exploitation of this vulnerability requires the "Save Avatars as Files" option
|
||||
to be enabled (disabled by default).
|
||||
|
||||
