CVE-2018-1260: Spring Security OAuth, versions 2.3 prior to 2.3.3, 2.2 prior to 2.2.2, 2.1 prior to 2.1.2, 2.0 prior to 2....

Security readout for executives and security teams

CVE-2018-1260 is a remote code execution flaw in Spring Security OAuth. If an affected authorization server processes a crafted authorization request and forwards the resource owner to the approval endpoint, attacker-controlled input can lead to code execution. Business urgency is highest for internet-facing OAuth authorization services still running old 2.x versions. Exposure is likely limited to applications using Spring Security OAuth as an authorization server, especially where the authorization endpoint is reachable by untrusted users. General Spring Security use is not enough evidence of exposure without this OAuth component and affected version range. Prioritize remediation for internet-facing identity or authorization services. This is not confirmed exploited in the provided sources, but the impact class is remote code execution in an authentication path, making stale deployments a material business risk. Mitigation focus: Upgrade Spring Security OAuth to 2.3.3, 2.2.2, 2.1.2, or 2.0.15 as applicable.; Remove or replace older unsupported Spring Security OAuth versions.; Apply relevant Red Hat advisories if consuming Spring Security OAuth through Red Hat packages..
