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 an injection vulnerability tracked as CVE-2023-29524 that permits arbitrary code execution under the privileges of the Scheduler Application sheet. The flaw stems from insufficient restrictions on the XWiki.SchedulerJobClass object type, allowing Groovy scripts placed in the Job Script field to run in the server context when the profile page is viewed.

An authenticated user without script or programming rights can exploit the issue by editing their own user profile through the object editor, inserting a malicious SchedulerJobClass instance. Successful exploitation grants the attacker the ability to execute arbitrary code on the server, resulting in full confidentiality, integrity, and availability impact as reflected in the CVSS 9.9 score.

Advisories published by the XWiki project, including GHSA-fc42-5w56-qw7h and the linked Jira issues, state that the vulnerability has been fixed in versions 14.10.3 and 15.0 RC1; administrators are advised to upgrade, and the project reports no known workarounds.

The EPSS score has remained steady at its peak value of 0.4773 with no material increase after 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.
