Sensitive data disclosure via incorrect attribute index
Published Oct 29, 2025 · Updated Oct 29, 2025
Buffer over-read in Wazuh manager before 4.10.2 allows remote authenticated users to read sensitive memory via crafted agent messages. DecodeWinevt passes the child-loop index j instead of the attribute-loop index l to child_attr[p]->attributes while resolving an mdebug2 argument, causing an out-of-bounds heap read. Exploitation requires an enrolled or compromised agent, and disclosure requires analysisd.debug=2; otherwise the over-read does not emit the affected memory.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
