SECUNIA ADVISORY ID:
SA18900

VERIFY ADVISORY:
http://secunia.com/advisories/18900/

CRITICAL:
Not critical

IMPACT:
Manipulation of data

WHERE:
>From remote

SOFTWARE:
Wimpy MP3 Player 5.x
http://secunia.com/product/8102/

DESCRIPTION:
ReZEN has reported a weakness in Wimpy MP3 Player, which can be
exploited by malicious people to modify certain data.

The weakness is caused due to wimpy_trackplays.php failing to
authenticate users before allowing access. This can be exploited to
write arbitrary contents into the "trackme.txt" file, which may
facilitate other attacks on the system.

Successful exploitation requires that the web server process has
write access to the "trackme.txt" file.

SOLUTION:
Change the file permissions of the "trackme.txt" file to prevent
modification or remove wimpy_trackplays.php if it is not required.

PROVIDED AND/OR DISCOVERED BY:
ReZEN
