Security readout for executives and security teams
CVE-2018-11091 lets a logged-in attacker upload a script to MyBiz MyProcureNet 5.0.0 by tampering with the upload extension whitelist. If the webserver executes that script, the attacker can run operating system commands and potentially take over the server. Exposure is most relevant to organizations running MyBiz MyProcureNet 5.0.0, especially where authenticated users can reach file upload functionality. The structured affected CPE data is absent, so asset confirmation must rely on product inventory and application review. Treat this as urgent if MyProcureNet 5.0.0 is present. A successful attack could compromise the application server, affecting confidentiality, integrity, and availability. If the product is not in use, document non-exposure and deprioritize. Mitigation focus: Identify any MyBiz MyProcureNet 5.0.0 deployments.; Check MyBiz or SEC Consult guidance for fixed versions or mitigations.; Restrict upload functionality to trusted, necessary users while assessing remediation..
