The root cause is insufficient synchronization and lack of robust final-path validation in the threat-removal workflow: the agent records an active-response action and proceeds to perform deletion without guaranteeing the deletion target is the originally intended file. This can result in SYSTEM-level arbitrary file or folder deletion and consequent local privilege escalation. Wazuh made an attempted fix via pull request 8697 on 2025-07-10, but that change was incomplete.<\/p>\n<p>Severity: 7.1 | HIGH<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-34294 Published : Oct. 28, 2025, 4:15 p.m. | 29\u00a0minutes ago Description : Wazuh&#8217;s File Integrity Monitoring (FIM), when configured with automatic threat removal, contains a time-of-check\/time-of-use (TOCTOU) race condition that can allow a local, low-privileged attacker to cause the Wazuh service (running as NT AUTHORITYSYSTEM) to delete attacker-controlled files or paths. &hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[26],"tags":[],"class_list":["post-72531","post","type-post","status-publish","format-standard","hentry","category-vulnerability"],"_links":{"self":[{"href":"https:\/\/afaghhosting.net\/blog\/wp-json\/wp\/v2\/posts\/72531","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/afaghhosting.net\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/afaghhosting.net\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/afaghhosting.net\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/afaghhosting.net\/blog\/wp-json\/wp\/v2\/comments?post=72531"}],"version-history":[{"count":0,"href":"https:\/\/afaghhosting.net\/blog\/wp-json\/wp\/v2\/posts\/72531\/revisions"}],"wp:attachment":[{"href":"https:\/\/afaghhosting.net\/blog\/wp-json\/wp\/v2\/media?parent=72531"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/afaghhosting.net\/blog\/wp-json\/wp\/v2\/categories?post=72531"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/afaghhosting.net\/blog\/wp-json\/wp\/v2\/tags?post=72531"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
