CVE-2025-61247 identifies a critical SQL Injection vulnerability in the indieka900 online-shopping-system-php version 1.0, located in the password parameter of the login.php script. SQL Injection (CWE-89) vulnerabilities occur when untrusted input is improperly sanitized and directly included in SQL queries, allowing attackers to manipulate the query structure. In this case, the password parameter is vulnerable, enabling an attacker to craft malicious input that could bypass authentication controls or execute arbitrary SQL commands. The vulnerability is remotely exploitable without authentication or user interaction, increasing its risk profile. The CVSS 3.1 base score of 8.2 reflects a network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), limited confidentiality impact (C:L), high integrity impact (I:H), and no availability impact (A:N). Exploiting this flaw could allow attackers to alter or bypass login credentials, access sensitive user data, or manipulate backend databases, severely compromising system integrity. Although no public exploits have been reported yet, the vulnerability's nature and ease of exploitation make it a significant threat to any deployment of this software. The lack of available patches necessitates immediate attention to alternative mitigation strategies.

For European organizations, particularly those operating e-commerce platforms using indieka900 online-shopping-system-php or similar PHP-based shopping systems, this vulnerability poses a substantial risk. Successful exploitation could lead to unauthorized access to customer accounts, exposure of personal and payment information, and potential manipulation of transaction data. This undermines customer trust and could result in regulatory penalties under GDPR due to data breaches. The integrity of the authentication mechanism is compromised, allowing attackers to escalate privileges or impersonate users. Although availability is not directly impacted, the reputational damage and potential financial losses from fraud or data theft are significant. The vulnerability's remote and unauthenticated exploitation vector increases the attack surface, making it attractive to cybercriminals targeting European online retailers. Organizations in countries with large e-commerce markets and stringent data protection laws face heightened risks and compliance challenges.

Given the absence of official patches, European organizations should implement immediate mitigations to reduce risk. First, apply strict input validation and sanitization on the password parameter, ensuring that only expected characters are accepted. Employ parameterized queries or prepared statements to prevent SQL Injection by separating code from data. If modifying the source code is not feasible, deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL Injection attempts targeting login.php. Conduct thorough code reviews and penetration testing to identify and remediate similar vulnerabilities elsewhere in the application. Monitor authentication logs for unusual patterns indicative of exploitation attempts, such as repeated failed logins with suspicious input. Educate development teams on secure coding practices to prevent future injection flaws. Finally, plan for an upgrade or migration to a more secure and actively maintained e-commerce platform to eliminate reliance on vulnerable software.
