CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:HSummary
CVE-2024-55662 is a critical-severity Static Code Injection (CWE-96) vulnerability in Xwiki Xwiki. Its CVSS base score is 9.9 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 48% 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 AC-24 (Access Control Decisions) and AC-25 (Reference Monitor) — 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 contains a remote code execution vulnerability affecting the Extension Repository Application component. The flaw impacts versions from 3.3-milestone-1 through 15.10.8 and 16.2.x, where the application fails to enforce proper authorization checks, allowing unauthorized code execution that requires programming rights. The issue is tracked under CVEs associated with static code injection, incorrect authorization, and improper code generation controls, and carries a CVSS score of 9.9.
Any authenticated user on an affected instance with the Extension Repository Application enabled can exploit the vulnerability to run arbitrary server-side code. Successful exploitation grants full control equivalent to programming rights, enabling actions such as data exfiltration, system modification, or further lateral movement within the environment.
Official advisories recommend upgrading to XWiki 15.10.9 or 16.3.0 to resolve the issue. As a workaround, administrators can disable the Extension Repository Application on instances that do not require it, or manually apply the security patches from commit 8659f17d500522bf33595e402391592a35a162e8 to the ExtensionCode.ExtensionSheet and ExtensionCode.ExtensionAuthorsDisplayer pages.
The EPSS score rose from a low baseline to a peak of 0.4754, indicating emerging exploitation interest after disclosure before receding to the current value of 0.1277.

Vulnerability Data
XWiki Platform is a generic wiki platform. Starting in version 3.3-milestone-1 and prior to versions 15.10.9 and 16.3.0, on instances where `Extension Repository Application` is installed, any user can execute any code requiring `programming` rights on the server. This vulnerability…

has been fixed in XWiki 15.10.9 and 16.3.0. Since `Extension Repository Application` is not mandatory, it can be safely disabled on instances that do not use it as a workaround. It is also possible to manually apply the patches from commit 8659f17d500522bf33595e402391592a35a162e8 to the page `ExtensionCode.ExtensionSheet` and to the page `ExtensionCode.ExtensionAuthorsDisplayer`.

Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly requires correct enforcement of authorization decisions on every access request, structurally preventing incorrect checks.
AC-24 ensures access-control decisions are made and applied consistently, reducing the chance of an incorrect authorization result.
A reference monitor that is always invoked and tamper-proof forces every authorization decision through a verified, correct path.
Developer testing and evaluation can discover missing neutralization of directives in saved code artifacts.
Input validation directly stops unneutralized directives from being inserted into static code resources.
Least-privilege assignments shrink the set of authorizations that must be checked correctly, limiting exposure to flawed checks.
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.
Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.
Secure SDLC practices directly require input neutralization to block static code injection into templates, configs, or libraries.
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.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing in development and acceptance will detect static code injection but does not prevent it at the source.
Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.
Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.
Secure development life cycle mandates input validation and sanitization that directly prevents static code injection.
Application security requirements include rules for neutralizing untrusted input before it is stored in executable resources.
Secure architecture principles reduce injection surfaces but do not prescribe the specific neutralization techniques.
