Unauthenticated OS Command Injection RCE in Progress Kemp LoadMaster API
CVE-2026-8037 is a critical remote code execution vulnerability affecting the API in Progress ADC products, including Progress Kemp LoadMaster. According to the provided content, the issue is an OS command injection flaw caused by unsanitized input in multiple command endpoints, allowing attacker-controlled input to reach operating system command execution paths. The vendor description states that an unauthenticated attacker can exploit the flaw to execute arbitrary commands on the LoadMaster appliance. Supporting content also references vulnerable API handling associated with the accessv2 endpoint and the apiuser parameter, though the broader vendor description characterizes the issue as affecting multiple command endpoints. Successful exploitation results in arbitrary command/code execution on the appliance, reportedly in the context of root.
