Vmware Spring Hateoas ≤ 1.5.5
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-34036 is a medium-severity Improper Neutralization of HTTP Headers for Scripting Syntax (CWE-644) vulnerability in Vmware Spring Hateoas. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 40th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

Vulnerability Data
Reactive web applications that use Spring HATEOAS to produce hypermedia-based responses might be exposed to malicious forwarded headers if they are not behind a trusted proxy that ensures correctness of such headers, or if they don't have anything else in…
more
place to handle (and possibly discard) forwarded headers either in WebFlux or at the level of the underlying HTTP server. For the application to be affected, it needs to satisfy the following requirements: * It needs to use the reactive web stack (Spring WebFlux) and Spring HATEOAS to create links in hypermedia-based responses. * The application infrastructure does not guard against clients submitting (X-)Forwarded… headers.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Validating that output matches expected content directly mitigates failures to properly encode or escape data for its destination context.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require proper output encoding and header sanitization to prevent scripting injection.

Secure development lifecycle mandates input validation and output encoding that directly prevents header-injection flaws.
A.8.26 only requires that security requirements (including resilience against injections) be identified and specified during development; it does not itself neutralize HTTP header syntax or stop exploitation of CWE-644
A.8.27 mandates security-by-design principles (including data validation/sanitization, distrust external input, defense-in-depth, secure architecture reviews against attack patterns) that reach output encoding and header sanitization for this XSS-like weakness in many but not all cases; a bounded remainder exists for non-web or non-HTTP contexts and incomplete application of the principles.
Secure coding standards require proper escaping or rejection of scripting syntax in HTTP headers.
Security testing catches header-injection issues before release, covering most of the weakness.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-116, a class-level weakness, and none of its children carries one either.
