|CVSS Meta Temp Score|
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
|Current Exploit Price (≈)|
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
|CTI Interest Score|
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.
A vulnerability was found in podman up to 1.6.x. It has been declared as critical. Affected by this vulnerability is some unknown functionality of the component Container Handler. The manipulation with an unknown input leads to a privilege escalation vulnerability. The CWE definition for the vulnerability is CWE-863. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:
A flaw was found in podman before 1.7.0. File permissions for non-root users running in a privileged container are not correctly checked. This flaw can be abused by a low-privileged user inside the container to access any other file in the container, even if owned by the root user inside the container. It does not allow to directly escape the container, though being a privileged container means that a lot of security features are disabled when running the container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
The weakness was released 02/12/2021. The advisory is shared at bugzilla.redhat.com. This vulnerability is known as CVE-2021-20188 since 12/17/2020. The exploitation appears to be easy. The attack can only be initiated within the local network. A single authentication is required for exploitation. Neither technical details nor an exploit are publicly available.
Upgrading to version 1.7.0 eliminates this vulnerability.
