Summary

CVE-2023-29214 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 8.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

XWiki Commons, the shared technical libraries used across multiple XWiki projects, contain a code-injection vulnerability in the IncludedDocuments panel. The flaw stems from improper escaping of included pages, which permits any user holding edit rights to inject and execute arbitrary Groovy, Python, or Velocity code. Successful exploitation grants the attacker complete control over the XWiki installation, corresponding to a CVSS 3.1 score of 9.9 and the weaknesses catalogued under CWE-94 and CWE-95.

An authenticated attacker with edit privileges can therefore achieve full confidentiality, integrity, and availability impact on the affected XWiki instance without user interaction. The attack is performed remotely over the network by crafting malicious page content that is rendered through the vulnerable panel.

The issue was corrected in the commits referenced in the GitHub Security Advisory GHSA-qx9h-c5v6-ghqh and tracked under XWIKI-20306; the fixes were released in XWiki 14.4.7 and 14.10. Administrators are advised to upgrade to one of these patched versions.

EPSS scores have remained low, with a current value of 0.0647 and a modest peak of 0.0728, indicating limited observed exploitation interest to date.

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.
