CVE-2022-36035: Flux is a tool for keeping Kubernetes clusters in sync with sources of configuration (like Git repositories), and automating updates to configuration when there is new code to deploy. Flux CLI allows users to deploy Flux components into a Kubernetes cluster via command-line. The vulnerability allows other applications to replace the Flux deployment information with arbitrary content which is deployed into the target Kubernetes cluster instead. The vulnerability is due to the improper handling of user-supplied input, which results in a path traversal that can be controlled by the attacker. Users sharing the same shell between other applications and the Flux CLI commands could be affected by this vulnerability. In some scenarios no errors may be presented, which may cause end users not to realize that something is amiss. A safe workaround is to execute Flux CLI in ephemeral and isolated shell environments, which can ensure no persistent values exist from previous processes. However, upgrading to the latest version of the CLI is still the recommended mitigation strategy.
The exploitability of CVE-2022-36035 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
The exploitability of CVE-2022-36035 is influenced by multiple factors. Security teams should analyze system configurations and apply appropriate countermeasures to mitigate threats.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2022-36035, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2022-36035, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.044% (probability of exploit)
EPSS Percentile: 12.55%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 87.45% of others.
