Published Aug 18, 2022CWE-354EPSS 0.28%

Overview

CVE-2022-29549 is a high-severity vulnerability. It was published on August 18, 2022 and has a CVSS 3.1 base score of 7.3 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.3, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

An issue was discovered in Qualys Cloud Agent 4.8.0-49. It executes programs at various full pathnames without first making ownership and permission checks (e.g., to help ensure that a program was installed by root) and without integrity checks (e.g., a checksum comparison against known legitimate programs). Also, the vendor recommendation is to install this agent software with root privileges. Thus, privilege escalation is possible on systems where any of these pathnames is controlled by a non-root user. An example is /opt/firebird/bin/isql, where the /opt/firebird directory is often owned by the firebird user.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
