See all- CVE-2018-16988Critical
An authentication bypass issue was discovered in Open XDMoD through version 7.5.0, which can lead to account takeover. A weak password reset mechanism allows an attacker to perform a brute-force attack on the MD5 rid value, requiring only 600 guesses if they know the victim initiated a password reset process in the past few minutes.
- CVE-2026-45776Medium
Open XDMoD before version 11.0.3 has a flaw in access control logic that allows an attacker to send a crafted HTTPS POST request setting a session variable used for authorization. If the optional Job Performance (SUPReMM) module is installed, the attacker can bypass data access restrictions and view other users' compute job efficiency metrics.
Original NVD description (English source)
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.
