TITLE: Bit 5 Blog Script Insertion and SQL Injection Vulnerabilities
SECUNIA ADVISORY ID: SA18464
VERIFY ADVISORY: http://secunia.com/advisories/18464/
CRITICAL: Moderately critical
IMPACT: Security Bypass, Cross Site Scripting, Manipulation of data
WHERE: >From remote
SOFTWARE: Bit 5 Blog 8.x http://secunia.com/product/6821/
DESCRIPTION: Aliaksandr Hartsuyeu has reported some vulnerabilities in Bit 5 Blog, which can be exploited by malicious people to conduct script insertion and SQL injection attacks.
1) Input passed to the "username" and "password" parameters in "processlogin.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.
2) Input passed to the "comment" parameter in "addcomment.php" isn't properly sanitised before being used. This can be exploited to inject arbitrary script code, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed.
The vulnerabilities have been reported in version 8.01. 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
