CVE-2025-6862 is a SQL Injection vulnerability identified in SourceCodester Best Salon Management System version 1.0, specifically within the /panel/edit_plan.php file. The vulnerability arises from improper sanitization or validation of the 'editid' parameter, which is directly used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the underlying database. The vulnerability does not require user interaction or authentication, making it remotely exploitable over the network. Although the CVSS 4.0 base score is 5.3 (medium severity), the exploitability is relatively straightforward due to low attack complexity and no required privileges. The impact on confidentiality, integrity, and availability is limited but present at a low level, as indicated by the CVSS vector components (VC:L, VI:L, VA:L). No patches or official mitigations have been published yet, and no known exploits are currently observed in the wild. However, public disclosure of the exploit code increases the risk of exploitation by opportunistic attackers. The vulnerability affects only version 1.0 of the product, which is a niche salon management system likely used by small to medium-sized businesses to manage appointments, client data, and service plans.

For European organizations using SourceCodester Best Salon Management System 1.0, this vulnerability could lead to unauthorized data access or modification, including client personal information and business records. While the impact is medium, exploitation could result in data breaches, loss of data integrity, or service disruption. This is particularly concerning for salons handling sensitive customer data subject to GDPR regulations, where unauthorized data exposure could lead to regulatory penalties and reputational damage. The remote exploitability without authentication increases the risk, especially for systems exposed to the internet or insufficiently segmented networks. However, given the niche nature of the product and the lack of widespread adoption, the overall impact on large European enterprises is limited. Small and medium enterprises (SMEs) in the beauty and wellness sector are more likely to be affected, potentially facing operational disruptions and compliance challenges.

1. Immediate mitigation should include restricting external access to the /panel/edit_plan.php endpoint via network controls such as firewalls or VPNs, limiting exposure to trusted internal networks only. 2. Implement input validation and parameterized queries or prepared statements in the application code to prevent SQL injection. Since no official patch is available, organizations should review and sanitize the 'editid' parameter handling in the source code. 3. Conduct thorough security testing and code review of the affected module to identify and remediate similar injection points. 4. Monitor web server logs for suspicious requests targeting the 'editid' parameter to detect potential exploitation attempts. 5. If feasible, isolate the salon management system from critical internal networks to reduce lateral movement risk. 6. Engage with the vendor or community to obtain or develop patches and apply them promptly once available. 7. Educate staff on the risks and ensure backups of critical data are maintained to enable recovery in case of compromise.
