Clusterlabs · Crmsh · CVE-2020-35459
**Name of the Vulnerable Software and Affected Versions**
ClusterLabs crmsh versions 4.2.1 and earlier
**Description**
The issue allows local attackers to execute commands via shell code injection to the `crm history` command line, potentially allowing escalation of privileges. This is related to a lack of privilege management mechanism in the cluster management shell. Exploitation of the issue could allow an attacker to access confidential data, compromise its integrity, and cause a denial of service.
**Recommendations**
For versions 4.2.1 and earlier, as a temporary workaround, consider restricting access to the `crm history` command until a patch is available. Avoid using the `crm history` command with untrusted input to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
