Attack Chain

1. The attacker identifies an endpoint that utilizes the vulnerable PageRequest function in PictureServiceImpl.java.
2. The attacker crafts a malicious HTTP request targeting the vulnerable endpoint.
3. The attacker injects a SQL payload into the sortField parameter of the PageRequest function.
4. The application processes the crafted request, passing the malicious SQL payload to the MyBatis-Plus component.
5. MyBatis-Plus executes the injected SQL query against the application’s database.
6. The database executes the injected SQL, potentially allowing the attacker to read, modify, or delete data.
7. The attacker retrieves sensitive information from the database, such as user credentials or configuration details.
8. The attacker uses the compromised data to further compromise the application or gain access to the underlying system.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2026-7060) can lead to unauthorized data access, modification, or deletion, potentially resulting in complete compromise of the application and its underlying database. The absence of versioning makes identifying vulnerable installations difficult. Given the publicly available exploit, affected organizations are at increased risk of attack.

Recommendation

• Apply the patch or update the liyupi yu-picture application to a version containing the fix for CVE-2026-7060 as soon as it becomes available.
• Implement input validation and sanitization on the sortField parameter within the PageRequest function to prevent SQL injection.
• Deploy the Sigma rule Detect Malicious SortField SQL Injection to identify attempts to exploit this vulnerability in web server logs.
• Monitor web server logs for suspicious activity targeting endpoints that use the PageRequest function.
