Deeper analysis

CVE-2019-25697 is an SQL injection vulnerability in CMSsite 1.0, affecting the category.php component through the cat_id parameter. It allows attackers to inject malicious SQL code into database queries via GET requests, enabling manipulation of the underlying database. The vulnerability is classified under CWE-89 and carries a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), indicating high confidentiality impact with low integrity impact and no availability disruption.

Unauthenticated remote attackers can exploit this vulnerability by sending crafted GET requests to category.php with malicious values in the cat_id parameter. Successful exploitation allows extraction of sensitive database information, including usernames and credentials, without requiring privileges, user interaction, or special conditions.

Advisories and resources, including those from Vulncheck (https://www.vulncheck.com/advisories/cmssite-sql-injection-via-category-php) and an Exploit-DB entry (https://www.exploit-db.com/exploits/46259), detail the issue and provide exploit code. The CMSsite source is available at https://github.com/VictorAlagwu/CMSsite/archive/master.zip; practitioners should review these for mitigation guidance, such as input validation or upgrades if patches exist.

A public exploit is available on Exploit-DB, highlighting the need for immediate scanning and patching of exposed CMSsite 1.0 instances.
