TITLE:
AlternC Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA23144

VERIFY ADVISORY:
http://secunia.com/advisories/23144/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Cross Site Scripting, Exposure of sensitive
information

WHERE:
>From remote

SOFTWARE:
AlternC 0.x
http://secunia.com/product/12782/

DESCRIPTION:
Vincent Audet Ménard has reported some vulnerabilities in AlternC,
which can be exploited by malicious users to disclose sensitive
information, to conduct script insertion attacks, or to bypass
certain security restrictions.

1) Input passed to parameters when creating directories is not
properly sanitised before being used. This can be exploited to insert
arbitrary HTML and script code which will be executed in a user's
browser session in context of an affected site when the malicious
data is viewed.

2) An input validation error exists when creating files and
directories. This can be exploited to create files and directories
via directory traversal attacks.

3) An input validation error exists when configuring a subdomain.
This can be exploited to gain read access to arbitrary files with
privileges of the web server by including directory traversal
sequences when specifying the web root.

4) An error exist due to the application storing the SQL password
within a cookie in plaintext once the user used phpmyadmin in
AlternC.

The vulnerabilities are reported in 0.9.5. Other versions may also be
affected.

SOLUTION:
Some vulnerabilities are reportedly fixed in version 0.9.6.
