DescriptionCVE.org

A vulnerability has been found in Evergreen up to 3.14.11/3.15.11/3.16.5/3.17-beta1. The affected element is an unknown function of the file /osrf-gateway-v1 of the component open-ils.fielder OpenSRF Service. Such manipulation leads to sql injection. The attack can be executed remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 3.14.12, 3.15.12, 3.16.6 and 3.17-beta2 is sufficient to fix this issue. The affected component should be upgraded.

AnalysisAI

SQL injection in Evergreen's open-ils.fielder OpenSRF Service, exposed via the /osrf-gateway-v1 HTTP gateway endpoint, affects all actively maintained branches through 3.14.11, 3.15.11, 3.16.5, and 3.17-beta1. The CVSS 4.0 vector confirms network-accessible, unauthenticated exploitation with low attack complexity, yielding partial confidentiality, integrity, and availability impact against the underlying database. A public proof-of-concept has been disclosed and patched releases (3.14.12, 3.15.12, 3.16.6, 3.17-beta2) are available, making delayed remediation difficult to justify given the exploit's public availability.

Technical ContextAI

Evergreen is an open-source integrated library system (ILS) used predominantly by public and academic libraries. Its backend relies on OpenSRF (Open Service Request Framework), a message-passing middleware layer; the /osrf-gateway-v1 endpoint acts as an HTTP-to-OpenSRF bridge, translating web requests into backend service calls. The open-ils.fielder service is a data-retrieval component that constructs database queries based on caller-supplied parameters. CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) indicates that user-controlled input reaching this service is not adequately sanitized or parameterized before inclusion in SQL statements. Because /osrf-gateway-v1 is typically exposed publicly to support the Evergreen OPAC (Online Public Access Catalog) and staff client, the injection surface is network-reachable without authentication. The CPE cpe:2.3:a:n/a:evergreen:*:*:*:*:*:*:*:* covers all platform variants of Evergreen across the affected version ranges.

RemediationAI

Upgrade to the patched release corresponding to your installed branch: 3.14.12, 3.15.12, 3.16.6, or 3.17-beta2, as detailed in the vendor security advisory at https://evergreen-ils.org/Evergreen-security-release-3-14-12-3-15-12-3-16-6-3-17-beta2. If immediate patching cannot be completed, consider restricting network access to the /osrf-gateway-v1 endpoint via firewall rules or reverse-proxy access controls to known staff or trusted IP ranges; note this will break public OPAC functionality for remote patrons and should be treated as a temporary measure only. Deploying a web application firewall (WAF) rule to detect and block SQL metacharacters in requests to /osrf-gateway-v1 is an additional compensating control, though WAF bypass is possible for sophisticated attackers and should not substitute for patching. Audit Evergreen database access logs for anomalous query patterns in the fielder service context as a detection measure.
