Information disclosure via unchecked SNMP engine ID copy
Published Nov 27, 2024 · Updated Nov 27, 2024
Stack buffer overflow in Zabbix Server and Proxy 7.0.0 through 7.0.2rc1 allows remote authenticated users to obtain limited data disclosure. The zbx_snmp_cache_handle_engineid function passes session->securityEngineIDLen to memcpy when copying into the fixed-size local_record.engineid buffer without first enforcing its maximum length. Exploitation requires high privileges and a crafted SNMP engine ID; the vendor reports confidentiality impact without integrity or availability impact.

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.
