Summary

CVE-2023-29512 is a critical-severity Injection (CWE-74) vulnerability in Xwiki Xwiki. Its CVSS base score is 9.9 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 36% 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 Platform contains a remote code execution vulnerability that affects the default-installed templates imported.vm, importinline.vm, and packagelist.vm. The root cause is insufficient escaping of data loaded from attachments, which permits any user holding edit rights on a page to inject and execute arbitrary Groovy, Python, or Velocity code. The flaw is tracked as CWE-74 and carries a CVSS 3.1 score of 9.9.

An attacker with the ability to edit any page, such as their own user profile, can upload a crafted attachment and trigger code execution that grants full control over the XWiki installation, including access to all content and server resources. Because the vulnerable templates are present by default, exploitation requires no additional configuration or elevated privileges beyond ordinary edit rights.

Official advisories and the XWiki security team recommend immediate upgrade to versions 15.0-rc-1, 14.10.1, 14.4.8, or 13.10.11; no workarounds are available. The associated EPSS score has remained stable at 0.2936 since disclosure.

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.

SA-11 Developer Testing and Evaluation
addresses: CWE-74

Developer assessments and testing (including injection-focused techniques) identify improper neutralization of special elements, and the verifiable flaw remediation corrects them pre-deployment.

SI-4 System Monitoring
addresses: CWE-74

Identifies indicators of injection attacks (command, SQL, LDAP, etc.) via anomaly and attack monitoring.

prevents

Secure development life cycle mandates input validation and output encoding that directly prevent injection flaws.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against injection attacks in software design.

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

Secure architecture principles reduce injection surfaces but do not prescribe specific neutralization techniques.
