CVE-2025-5206 is a SQL Injection vulnerability identified in Pixelimity version 1.0, specifically within the installation component located at /install/index.php. The vulnerability arises from improper sanitization or validation of the 'site_description' parameter, which can be manipulated by an attacker to inject malicious SQL code. This injection flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring user interaction or authentication. The vulnerability is classified with a CVSS 4.0 base score of 5.1, indicating a medium severity level. The vector metrics indicate that the attack can be performed remotely (AV:N), with low attack complexity (AC:L), no privileges required (PR:H is contradictory but likely means high privileges are required, which reduces severity), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The scope remains unchanged (S:N), and no security requirements are bypassed (SI:N, SA:N). Although the vulnerability is publicly disclosed, there are no known exploits in the wild at this time. The lack of a vendor project or patch links suggests that Pixelimity may be a less widely known or niche product, potentially limiting immediate widespread exploitation but still posing a risk to users of this software. The vulnerability's presence in the installation script could allow attackers to compromise the database during setup or reconfiguration phases, potentially leading to data leakage, unauthorized data modification, or denial of service if exploited effectively.

For European organizations using Pixelimity 1.0, this SQL Injection vulnerability could lead to unauthorized access to sensitive data stored in the backend database, including potentially personal data protected under GDPR. The ability to execute arbitrary SQL commands remotely without user interaction increases the risk of data breaches, data tampering, or service disruption. Although the CVSS score is medium, the impact on confidentiality, integrity, and availability is non-negligible, especially if the database contains critical business or customer information. Organizations in sectors such as e-commerce, healthcare, or public services that rely on Pixelimity for web presence or content management could face reputational damage, regulatory penalties, and operational disruptions. The vulnerability's exploitation during installation or configuration phases might also allow attackers to establish persistent backdoors or escalate privileges within the affected environment.

European organizations should immediately audit their use of Pixelimity 1.0 and assess exposure to the vulnerable /install/index.php component. If possible, restrict access to the installation directory via network controls or web server configuration to trusted administrators only. Implement web application firewalls (WAFs) with specific rules to detect and block SQL injection attempts targeting the 'site_description' parameter. Conduct thorough input validation and sanitization on all user-supplied data, especially during installation processes. If a patch or updated version becomes available, prioritize timely application. In the absence of official patches, consider isolating the Pixelimity installation environment or migrating to alternative, actively maintained software. Regularly monitor logs for suspicious SQL activity and conduct penetration testing focused on injection vulnerabilities. Additionally, ensure database accounts used by Pixelimity have the least privileges necessary to limit potential damage from exploitation.
