AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
SQL injection in DCFM Blog 0.9.4 comments.php allows unauthenticated remote attackers to execute arbitrary SQL commands via the id parameter.
Vulnerability
DCFM Blog version 0.9.4 contains a SQL injection vulnerability in the comments.php script. The id parameter passed via POST is not sanitized before being used in a SQL query, allowing an attacker to inject arbitrary SQL commands. The vulnerability is present in the default installation and does not require any special configuration to be exploitable [1][2].
Exploitation
An unauthenticated remote attacker can exploit this vulnerability by sending a crafted POST request to comments.php with a malicious id parameter. The provided exploit example uses a UNION-based injection to extract data from the accounts table, such as usernames and passwords. No authentication or user interaction is required; the attacker only needs network access to the target web server [1][2].
Impact
Successful exploitation allows the attacker to execute arbitrary SQL commands, leading to partial disclosure of sensitive information (e.g., user credentials), potential modification of database content, and possible compromise of the application's integrity and availability. The CVSS base score is 7.5 (High) with partial impacts on confidentiality, integrity, and availability [1][2].
Mitigation
As of the publication date (2008-06-12), no official patch or fixed version has been released for DCFM Blog 0.9.4. Users are advised to upgrade to a newer version if available, or to apply input validation and parameterized queries to the id parameter in comments.php. The vulnerability is listed in the Exploit Database (EDB-ID 5772) [1][2].

Vulnerability mechanics
Root cause
"Missing input sanitization on the `id` parameter in `comments.php` allows SQL injection."
Attack vector
An unauthenticated remote attacker sends a POST request to `comments.php` with a crafted `id` parameter containing SQL metacharacters. The proof-of-concept payload `-99' union select 0,username,password from accounts where id=1/*` demonstrates how an attacker can extract credentials from the `accounts` table [ref_id=1][ref_id=2]. No authentication or special network position is required [CWE-89].
Affected code
The vulnerability resides in `comments.php` of DCFM Blog 0.9.4. The `id` parameter, passed via POST, is directly interpolated into an SQL query without sanitization [ref_id=1][ref_id=2].
What the fix does
No patch is included in the bundle. The advisory does not provide remediation code. To fix the issue, the application must properly escape or parameterize the `id` value before including it in an SQL query, for example by using prepared statements or input validation that rejects non-numeric content [CWE-89].
Preconditions
- authNo authentication required
- networkAttacker must be able to send HTTP POST requests to the target
- inputThe id parameter is accepted without sanitization
Reproduction
1. Host DCFM Blog 0.9.4 at a local or remote web server. 2. Send a POST request to `http://target/dcfmblog/comments.php` with body: `id=-99' union select 0,username,password from accounts where id=1/*` 3. The response will include the username and password hash from the `accounts` table in place of the expected comment data [ref_id=1][ref_id=2].
