AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A flaw was found in Keylime before 6.3.0. The logic in the Keylime agent for checking for a secure mount can be fooled by previously created unprivileged mounts allowing secrets to be leaked to other processes on the host.

CVE-2022-23948 is a high-severity vulnerability affecting Keylime versions prior to 6.3.0. Keylime is an open-source remote attestation framework designed to verify the integrity of hosts in cloud and edge computing environments. The vulnerability is classified under CWE-200, which pertains to information exposure. Specifically, the flaw resides in the Keylime agent's logic for verifying secure mounts. The agent attempts to ensure that sensitive data, such as cryptographic secrets, are stored only on secure mounts. However, this logic can be bypassed if an attacker creates unprivileged mounts prior to the agent's check. These pre-existing mounts can trick the agent into believing the environment is secure, thereby allowing secrets to be leaked to other processes running on the same host. The vulnerability does not require any privileges or user interaction to exploit (CVSS vector: AV:N/AC:L/PR:N/UI:N), making it remotely exploitable over the network without authentication. The impact is a high confidentiality breach, as secrets intended to be protected by secure mounts can be accessed by unauthorized processes. There is no indication of integrity or availability impact. No known exploits are currently reported in the wild, but the vulnerability's nature and ease of exploitation make it a significant risk, especially in multi-tenant or shared environments where isolation is critical. The issue was addressed in Keylime version 6.3.0, which presumably includes improved mount verification logic to prevent this bypass.
