CVE-2025-5205 is a SQL Injection vulnerability identified in version 1.0 of the '1000 Projects Daily College Class Work Report Book' application, specifically within the /dcwr_entry.php file. The vulnerability arises from improper sanitization or validation of the 'Date' parameter, which is directly used in SQL queries. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially manipulating the database queries executed by the application. Given that no authentication or user interaction is required, the attack surface is broad. Exploitation could lead to unauthorized data access, data modification, or even deletion, depending on the database privileges of the application. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with the vector showing network attack vector, low attack complexity, no privileges or user interaction needed, and low impact on confidentiality, integrity, and availability. Although no public exploits are currently known to be actively used in the wild, the disclosure of the vulnerability and the availability of exploit information increase the risk of exploitation. The affected product appears to be a niche educational software tool used for managing daily class work reports, which may be deployed in academic institutions or educational organizations.

For European organizations, particularly educational institutions using the '1000 Projects Daily College Class Work Report Book' software, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive academic data, including student attendance, performance records, and scheduling information. Such data breaches could violate GDPR regulations, leading to legal and financial repercussions. Additionally, manipulation or deletion of records could disrupt academic operations, affecting data integrity and availability. Given the remote and unauthenticated nature of the exploit, attackers could leverage this vulnerability to establish a foothold within the institution's network, potentially escalating to broader attacks. The medium severity rating suggests moderate impact, but the critical nature of educational data and regulatory environment in Europe elevates the importance of addressing this vulnerability promptly.

1. Immediate patching: Organizations should seek updates or patches from the vendor '1000 Projects' to remediate the vulnerability. If no official patch is available, consider applying virtual patches via Web Application Firewalls (WAFs) to block malicious payloads targeting the 'Date' parameter. 2. Input validation and sanitization: Implement strict server-side validation and sanitization of all user inputs, especially the 'Date' parameter, to prevent injection of malicious SQL code. 3. Principle of least privilege: Ensure that the database user account used by the application has minimal privileges, limiting the potential damage of a successful injection. 4. Network segmentation: Isolate the application server within a segmented network zone to reduce lateral movement opportunities for attackers. 5. Monitoring and logging: Enable detailed logging of database queries and web application requests to detect anomalous activities indicative of SQL injection attempts. 6. Incident response readiness: Prepare incident response plans specific to database breaches and ensure staff are trained to respond to potential exploitation events. 7. Vendor engagement: Engage with the software vendor to obtain security updates and request transparency on remediation timelines.
