Description


Jiko has discovered two vulnerabilities in Super Simple Blog Script, which can be exploited by malicious people to conduct SQL injection attacks, bypass certain security restrictions, and disclose sensitive information.

1) Input passed to the "entry" parameter in comments.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "entry" parameter in comments.php is not properly verified before being used to read and write files. This can be exploited to append or read data from arbitrary files via directory traversal sequences and URL-encoded NULL-bytes.

Successful exploitation of this vulnerability requires that "magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 2.5.4. Other versions may also be affected.


Solution:
Edit the source code to ensure that input is properly sanitised and verified.

Provided and/or discovered by:
