Detailsinfo

A vulnerability classified as critical has been found in HKUDS OpenHarness (unknown version). Affected is an unknown code block. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

HKUDS OpenHarness contains a remote code execution vulnerability in the /bridge slash command that allows remote senders accepted by configuration to execute arbitrary operating system commands. Attackers can invoke the /bridge spawn command with attacker-controlled command text that is forwarded to the bridge session manager and executed through the shared shell subprocess helper, allowing them to spawn shell sessions as the OpenHarness process user and access local files, credentials, workspace state, and repository contents.
