Summary

Hide ▲

The XWiki exploit activity is now installing a cryptocurrency miner, turning CVE-2025-24893 abuse into direct resource theft on exposed servers. Attackers are using a two-pass workflow in which the first stage writes a downloader to disk and the later stage executes it. The flaw enables remote, unauthenticated code execution through the SolrSearch macro, making unpatched deployments easy to abuse. Earlier reconnaissance and current mining activity show the exploitation is being reused operationally rather than tested once.

    CVE-2025-24893 exploitation deploys a cryptocurrency miner on XWiki

    Exploitation Observed

    VulnCheck says CVE-2025-24893 in XWiki has been exploited in the wild to deploy a low-end cryptocurrency miner against exposed XWiki servers. The observed abuse used the SolrSearch macro to reach remote unauthenticated code execution, and the exploitation proceeded in a two-pass workflow in which the first pass staged a downloader by writing a file to disk and the second pass executed it later; the attacker traffic was geolocated in Vietnam, and CrowdSec earlier this year also saw reconnaissance against the same vulnerability.
