Summary

CVE-2023-35150 is a critical-severity Eval Injection (CWE-95) vulnerability in Xwiki Xwiki. Its CVSS base score is 9.9 (Critical).

Operationally, ranked in the top 0.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

XWiki Platform, a generic wiki platform, contains a remote code execution vulnerability affecting versions from 2.40m-2 up to but not including 14.4.8, 14.10.4, and 15.0. The flaw, tracked under CWE-94 and CWE-95, allows any user with view rights on a document to execute arbitrary code with programming rights by supplying a malicious payload through a crafted URL.

An attacker with minimal privileges can exploit the issue over the network without user interaction, achieving full confidentiality and integrity impact along with partial availability loss as reflected in the CVSS 9.9 score. Successful exploitation grants the ability to run code in the context of the XWiki application server.

Official patches are available in XWiki releases 15.0, 14.10.4, and 14.4.8, with corresponding fixes documented in the project’s GitHub security advisory and commit history. The current EPSS score of 0.3463, with a recorded peak of 0.3785, indicates sustained exploitation interest following disclosure.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly blocks the crafted malicious URL payload that triggers server-side code execution under CWE-94/95.

SI-2 Flaw Remediation good match
prevent

Requires prompt application of the vendor patches released in 15.0/14.10.4/14.4.8 that close the RCE vector.

AC-6 Least Privilege partial match
prevent

Limits the ability of view-only users to obtain programming rights, reducing the impact of any successful input-driven escalation.

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.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input neutralization and avoidance of unsafe dynamic evaluation.

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

A.8.29 Security testing in development and acceptance mostly match
detects

Security testing in development can detect eval injection vulnerabilities before deployment.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and safe coding practices that directly prevent eval injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements include rules against dynamic code execution of untrusted input.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles discourage unsafe dynamic evaluation constructs.

A.8.28 Secure coding partial match
prevents

Secure coding explicitly requires neutralization of input before dynamic evaluation, directly mitigating eval injection.

A.8.31 Separation of development, test and production environments none match
none

Separation of environments limits the blast radius if eval injection occurs in non-production.
