CriticalCVSS 9.3 · v2.0—Proof of concept No fix recorded

Noroxi assessment

Priority: Monitor (action score 39/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 7.5% (FIRST EPSS); higher than 94.5% of all records.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Splunk 4.2.5 and earlier, when a Free license is selected, enables potentially undesirable functionality within an environment that intentionally does not support authentication, which allows remote attackers to (1) read arbitrary files via a management-console session that leverages the ability to create crafted data sources, or (2) execute management commands via an HTTP request.

    Weakness class (CWE)

    CWE-287 · Improper Authentication

    CVSS vector

    AV:N/AC:M/Au:N/C:C/I:C/A:C

    nvd-primary

    Root cause

    Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.

    The bug in code

    The whole CWE-287 class

    A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

    Vulnerable

    ts
    app.use("/admin", requireSession, adminRouter);
// Route added later skips the middlewareapp.post("/admin-api/config", updateConfig);

    Fixed

    ts
    const admin = express.Router();admin.use(requireSession, requireRole("admin"));
admin.post("/config", updateConfig);app.use("/admin", admin);
