CVE-2026-45777: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in ubccr 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.
AI Analysis
Technical Summary
CVE-2026-45777 is an OS command injection vulnerability in the Open XDMoD framework (versions 9.5.0 to 11.0.2). It allows unauthenticated remote attackers to execute arbitrary system commands on the hosting web server with the same privileges as the web server process. This vulnerability arises from improper neutralization of special elements in OS commands (CWE-78). The issue was privately reported on 2026-04-06 and patched in version 11.0.3 on 2026-05-12. The CVSS 4.0 base score is 9.3, indicating critical severity with network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation enables remote attackers to execute arbitrary commands on the affected server with web server privileges. This can result in unauthorized reading or modification of application data, alteration of system configuration, or disruption of service availability. No known exploitation in the wild has been reported to date.
Mitigation Recommendations
A fixed version (11.0.3) of Open XDMoD is available and should be applied to remediate this vulnerability. If immediate upgrade is not possible, manually applying the patch released on 2026-05-12 is recommended. Patch status is confirmed by the vendor advisory indicating the issue was resolved in version 11.0.3.
