Summary

CVE-2023-29211 is a critical-severity Eval Injection (CWE-95) vulnerability in Xwiki Xwiki. Its CVSS base score is 9.9 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique JavaScript (T1059.007); ranked in the top 35% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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 Commons, the shared technical libraries used across multiple XWiki projects, contain an improper input sanitization flaw in the WikiManager.DeleteWiki action. The vulnerability stems from missing escaping of the wikiId URL parameter, which permits injection of Groovy, Python, or Velocity code. Any authenticated user holding view rights on the affected wiki component can trigger the flaw, resulting in arbitrary code execution with full control over the XWiki installation. The issue is tracked under CWE-95 and CWE-94 and carries a CVSS 3.1 score of 9.9.

An attacker with minimal view privileges can supply a crafted wikiId value to the DeleteWiki endpoint and execute server-side scripts. Successful exploitation grants complete read, write, and administrative access to the XWiki instance without requiring further user interaction or elevated permissions.

The GitHub Security Advisory GHSA-w7v9-fc49-4qg4 and the linked XWiki Jira ticket XWIKI-20297 state that the flaw is resolved in versions 13.10.11, 14.4.7, and 14.10. Corresponding commits in the xwiki-platform repository add proper escaping to the wikiId parameter, and administrators are advised to upgrade to one of the patched releases.

EPSS scores have remained low, with a current value of 0.0781 and a peak of 0.0847, indicating limited observed exploitation interest since disclosure.

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.

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.

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.

finds

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

prevents

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

prevents

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

prevents

Secure architecture principles discourage unsafe dynamic evaluation constructs.

prevents

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

none

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