CVE-2025-7610 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Electricity Billing System, specifically within the /user/change_password.php file. The vulnerability arises from improper handling of the 'new_password' parameter, which can be manipulated by an attacker to inject malicious SQL code. This injection flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands on the backend database without requiring any user interaction or privileges. The vulnerability is exploitable over the network (AV:N), with low attack complexity (AC:L), no authentication required (AT:N), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is limited but present (VC:L, VI:L, VA:L), indicating that an attacker could potentially read, modify, or delete sensitive data within the database. The vulnerability does not affect system confidentiality, integrity, or availability at a high level, but the ability to manipulate password change functionality could lead to unauthorized account access or privilege escalation. Although no public exploits are currently known in the wild, the exploit details have been disclosed publicly, increasing the risk of exploitation. The CVSS 4.0 base score is 6.9, categorizing it as medium severity. The vulnerability affects only version 1.0 of the Electricity Billing System, which is a specialized application used for managing electricity billing operations. No patches or fixes have been linked yet, so organizations using this version remain exposed. The vulnerability's presence in a critical infrastructure-related system like electricity billing raises concerns about potential disruption or unauthorized access to billing data and user accounts.

For European organizations, especially utility providers and electricity distribution companies using the affected Electricity Billing System version 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to user accounts, manipulation of billing data, and potential disruption of billing operations. This could result in financial losses, regulatory non-compliance (e.g., GDPR violations due to exposure of personal data), and reputational damage. Given the critical nature of electricity infrastructure, any compromise could also have cascading effects on operational technology systems if integrated. The ability to remotely exploit this vulnerability without authentication increases the threat level, particularly for organizations with internet-facing instances of the affected software. Although the impact on system availability is limited, the integrity and confidentiality risks are sufficient to warrant urgent attention. Additionally, the public disclosure of the exploit details increases the likelihood of opportunistic attacks targeting European utilities that have not yet applied mitigations.

1. Immediate mitigation should involve isolating the affected Electricity Billing System from direct internet exposure by implementing network segmentation and firewall rules restricting access to trusted internal networks only. 2. Conduct a thorough inventory to identify all instances of the Electricity Billing System version 1.0 in use. 3. Apply input validation and parameterized queries or prepared statements in the /user/change_password.php functionality to prevent SQL injection. If source code modification is not feasible immediately, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting the 'new_password' parameter. 4. Monitor logs for suspicious activities related to password changes or SQL errors indicative of injection attempts. 5. Engage with the vendor or community to obtain patches or updates addressing this vulnerability as soon as they become available. 6. Educate IT and security teams about this vulnerability and ensure incident response plans are updated to handle potential exploitation scenarios. 7. Consider implementing multi-factor authentication (MFA) on user accounts to reduce the impact of compromised credentials resulting from exploitation.
