Deeper analysis

CVE-2019-25521 is an SQL injection vulnerability (CWE-89) in XooGallery Latest, affecting the gal.php component through the gal_id parameter. This flaw allows attackers to inject malicious SQL code into database queries via GET requests. The vulnerability has 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 impact.

Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no privileges required. By sending crafted GET requests to gal.php with malicious values in the gal_id parameter, they can manipulate database queries to extract sensitive information or modify database contents.

Advisories and related resources, including those from VulnCheck and an exploit listing on Exploit-DB (46609), detail the vulnerability but do not specify patches or mitigations in the provided information. Security practitioners should review these references for PoC details and apply input validation or upgrade to a patched version if available.
