Published: 31 July 2024
Summary
CVE-2024-37901 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 6.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
XWiki Platform, a generic wiki platform, contains a remote code execution vulnerability that permits arbitrary code execution through improper handling of SearchSuggestConfig and SearchSuggestSourceClass objects. The flaw stems from missing authorization checks combined with unsafe code evaluation, allowing injection of executable content. It affects all installations prior to the listed patch releases and carries a CVSS score of 9.9 due to its network-accessible, low-complexity nature and full impact on confidentiality, integrity, and availability.
Any authenticated user granted edit rights on at least one page can exploit the issue by creating instances of the affected classes on their user profile or another accessible document. Successful exploitation grants the attacker full remote code execution privileges over the XWiki installation, enabling complete compromise of the underlying system and all hosted content.
The official GitHub Security Advisory and accompanying commits indicate that the vulnerability is resolved in XWiki 14.10.21, 15.5.5, and 15.10.2. Administrators are advised to upgrade to one of these versions; the referenced patches restrict object instantiation and enforce proper authorization around the Search Suggest configuration classes.
EPSS remains flat at 0.0974 with no material increase 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.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
