SECUNIA ADVISORY ID: SA18761
VERIFY ADVISORY: http://secunia.com/advisories/18761/
CRITICAL: Moderately critical
IMPACT: Manipulation of data, Security Bypass
WHERE: >From remote
SOFTWARE: GuestBookHost http://secunia.com/product/1765/
DESCRIPTION: Aliaksandr Hartsuyeu has reported two vulnerabilities in GuestBookHost, which can be exploited by malicious people to conduct SQL injection attacks.
Input passed to the "email" and "password" fields in "config.php" isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation requires that "magic_quotes_gpc" is disabled.
The vulnerabilities have been reported in version 2005.04.25. Other versions may also be affected.
SOLUTION: Edit the source code to ensure that input is properly sanitised.
PROVIDED AND/OR DISCOVERED BY: Aliaksandr Hartsuyeu
