Re: [Full-disclosure] Full Path Disclosure in most wordpress' plugins [?]

Hello,

Yes at some point you are right but this is not an option most of the times,
especially when you are on a shared hosting environment.

So either the developers need to secure their plugins or we do it ourselves
as this is still an issue for everybody using Wordpress Plugins.

The proposed fix is definitely something that helps. But to me it  
looks like most people do not care anymore about server settings. As  
soon as it is kind of working, it is pushed to the Internet.

Why not avoid these problems completely and follow the recommendations  
in php.ini?

; Print out errors (as a part of the output).  For production web sites,
; you're strongly encouraged to turn this feature off, and use error  
logging
; instead (see below).  Keeping display_errors enabled on a production  
web site
; may reveal security information to end users, such as file paths on  
your Web
; server, your database schema or other information.
;
; possible values for display_errors:
;
; Off        - Do not display any errors
; stderr     - Display errors to STDERR (affects only CGI/CLI binaries!)
; stdout (On) - Display errors to STDOUT
;
display_errors = Off

; Even when display_errors is on, errors that occur during PHP's startup
; sequence are not displayed.  It's strongly recommended to keep
; display_startup_errors off, except for when debugging.
display_startup_errors = Off

; Log errors into a log file (server-specific log, stderr, or  
error_log (below))
; As stated above, you're strongly advised to use error logging in  
place of
; error displaying on production web sites.
log_errors = On


Now the error message is in the logfile and nothing is displayed in  
the browser.
