| Vetor | AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L |
Name of the Vulnerable Software and Affected Versions
libvirt versions 4.8.0 and above
Description
The issue is related to an incorrect permissions check in the libvirt library, which manages virtualization. This could allow a remote attacker to gain access to confidential information or cause a denial of service. The problem arises because the readonly permission is allowed to invoke APIs that depend on the guest agent, potentially leading to the disclosure of unintended information or a denial of service by causing libvirt to block.
Recommendations
For libvirt versions 4.8.0 and above, consider restricting access to the guest agent APIs to prevent potential exploitation until a patch is available. As a temporary workaround, review and adjust the permissions settings to ensure that the readonly permission does not invoke sensitive APIs.
