CVE-2025-7935 is a SQL Injection vulnerability identified in the fuyang_lipengjun platform, specifically affecting the SysLogController function within the platform-admin/src/main/java/com/platform/controller/SysLogController.java file. The vulnerability arises from improper sanitization or validation of the 'key' argument, which can be manipulated by an attacker to inject malicious SQL code. This flaw allows an attacker to execute arbitrary SQL commands remotely without requiring user interaction or elevated privileges beyond limited privileges (PR:L). The platform uses a rolling release model, which means continuous delivery without fixed version numbers, complicating precise version tracking for affected or patched releases. The vulnerability has a CVSS 4.0 base score of 5.3, indicating a medium severity level. The vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The vulnerability could allow attackers to extract sensitive data, modify or delete logs, or potentially escalate privileges depending on the backend database and application logic. Given the critical nature of SQL injection vulnerabilities in general, this issue warrants prompt attention despite the medium CVSS score, especially considering the remote exploitability and potential for data compromise.

For European organizations using the fuyang_lipengjun platform, this vulnerability poses a risk of unauthorized data access and manipulation. Attackers could exploit the SQL injection to retrieve sensitive information from backend databases, including user credentials, system logs, or business-critical data. The integrity of system logs could be compromised, hindering forensic investigations and incident response. The availability of the platform could also be affected if attackers execute destructive SQL commands. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, could face compliance violations and reputational damage if exploited. The rolling release nature of the platform may delay patch deployment, increasing exposure time. Additionally, the remote exploitability without user interaction means that attackers can automate attacks, potentially targeting multiple organizations simultaneously. The medium severity rating suggests moderate impact, but the real-world consequences could be more severe depending on the deployment context and data sensitivity.

1. Immediate code review and sanitization: Review the SysLogController code to ensure all inputs, especially the 'key' parameter, are properly sanitized and validated using parameterized queries or prepared statements to prevent SQL injection. 2. Implement Web Application Firewall (WAF): Deploy a WAF with rules to detect and block SQL injection attempts targeting the platform. 3. Monitor logs and alerts: Enhance monitoring to detect unusual database queries or access patterns that may indicate exploitation attempts. 4. Patch management: Although no fixed version patches are available due to rolling releases, coordinate with the vendor or development team to obtain and apply the latest secure commits or hotfixes addressing this vulnerability. 5. Restrict database permissions: Limit the database user privileges used by the platform to the minimum necessary, reducing the potential impact of SQL injection. 6. Network segmentation: Isolate critical systems and databases to reduce exposure to remote attacks. 7. Conduct penetration testing: Regularly test the platform for injection vulnerabilities and other security issues to proactively identify and remediate weaknesses. 8. Educate developers: Provide secure coding training focused on injection flaws and input validation best practices to prevent future vulnerabilities.
