When the app renders untrusted content as a Velocity template, exploitation is unauthenticated, network-reachable, low-complexity RCE with full CIA loss; the untrusted-template requirement is an application deployment condition, not a base metric.

DescriptionCVE.org

A Server-Side Template Injection (SSTI) vulnerability in the Velocity template engine configuration of xdocreport v0.9.2 to v2.2.0 allows attackers to execute arbitrary code via a crafted expression.

AnalysisAI

Remote code execution in opensagres xdocreport (versions 0.9.2 through 2.2.0) arises because the bundled Velocity template engine ships with the insecure default UberspectImpl introspector, letting a crafted Velocity expression reach reflective JDK classes and run arbitrary code. Any application that renders untrusted template content through xdocreport's Velocity engine is exposed to full server compromise. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that attacker-controlled content be rendered as a Velocity template by an application using xdocreport 0.9.2-2.2.0 with the default (unmodified) introspector configuration - i.e., the app must expose a path where user input reaches the Velocity engine as template source or an evaluated expression. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The supplied CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N, C:H/I:H/A:H, score 9.8) treats this as trivially exploitable unauthenticated RCE, which holds ONLY when the embedding application feeds attacker-controlled content into a Velocity template. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upstream fix available (PR/commit); released patched version not independently confirmed - apply the change in https://github.com/opensagres/xdocreport/pull/723, which sets runtime.introspector.uberspect to org.apache.velocity.util.introspection.SecureUberspector by default and restricts reflective classes/packages; upgrade to a release built after v2.2.0 that incorporates PR #723 once published, or build from the patched source. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, audit all applications and systems in your environment to identify usage of OpenSagres XDocReport versions 0.9.2-2.2.0 and assess whether they process untrusted or external document templates; activate incident response protocols and immediately restrict network access to vulnerable systems from internet-facing networks. …
