CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Check for unusual JSON payloads containing SQL keywords like UNION, SELECT, or INSERT. Inspect Evergreen logs for repeated failed queries or time delays in responses, which may indicate blind SQL injection attempts.

Impact Analysis

This vulnerability enables full read access to the Evergreen database, exposing sensitive data such as patron personally identifiable information, password hashes, circulation history, and financial records. In some configurations, attackers may also gain write access, allowing them to request password resets for admin accounts and exfiltrate password reset tokens to gain full administrative access.

Mitigation Strategies

Immediately upgrade Evergreen to version 3.14.12, 3.15.12, 3.16.6, or 3.17-beta2 or later. Temporarily restrict access to the /osrf-gateway-v1 endpoint via firewall rules until patching is complete. Review database logs for signs of exploitation and rotate all administrative credentials if compromise is suspected.
