Sense of Security - Security Advisory - SOS-11-007
|
|
|
|
Release Date. 20-May-2011
|
|
Last Update. -
|
|
Vendor Notification Date. 04-Apr-2011
|
|
Product. Securimage / PHPCaptcha
|
|
Platform. PHP
|
|
Affected versions. 1.0.4 - 2.0.2
|
|
Severity Rating. Medium
|
|
Impact. Authentication bypass
|
|
Attack Vector. Remote without authentication
|
|
Solution Status. Vendor workaround
|
|
(remove securimage_play.php)
|
|
CVE reference. Not yet assigned
|
|
|
|
Details.
|
|
PHPCaptcha, also known as Securimage, is a popular Open Source PHP
|
|
CAPTCHA library. It is also used in popular WordPress plugins such as
|
|
the 'Fast Secure Contact Form'. Insufficient distortion in the audio
|
|
version of the CAPTCHA allows an attacker to quickly decode the CAPTCHA
|
|
by performing basic binary analysis of the generated audio file. The
|
|
issue is compounded by the fact that even if the audio feature of the
|
|
CAPTCHA has been disabled, it can still be accessed by forceful
|
|
browsing to the /secure_play.php URI.
|
|
|
|
Proof of Concept.
|
|
Proof of concept code that works against the example_form.php page and
|
|
the MP3 file format provided with the standard PHPCaptcha package
|
|
available from www.phpcaptcha.org is available at:
|
|
|
|

|
|
Mirror: https://github.com/offensive-security/exploitdb-bin-sploits/raw/master/bin-sploits/17309.zip (SOS-11-007.zip)
|
|
|
|
Proof of concept code is only available for the MP3 version of the
|
|
audio, however the WAV audio format is also affected by the same
|
|
vulnerability.
|
|
|
|
Solution.
|
|
Remove the script securimage_play.php and disable the use of the Audio
|
|
CAPTCHA.
