CVE-2026-45777: Buffalo open xdmod os command injection vulnerability

Buffalo · Open Xdmod

OpenXDMoD is an open framework for collecting and analyzing HPC metrics. Starting in version 9.5.0 and prior to version 11.0.3, an attacker can remotely execute arbitrary system commands on the web server hosting Open XDMoD with the privileges of the web server process. This could allow an attacker to read or modify application data, alter system configuration, or disrupt service availability. All deployments of Open XDMoD versions 9.5.0 through 11.0.2 (inclusive) are impacted. This issue was reported privately on 2026-04-06, and at this time there is no evidence that this vulnerability has been exploited in the wild. The vulnerability was patched in Open XDMoD 11.0.3 on 2026-05-12. As a workaround, apply the patch manually.
