CVE-2022-24348 is a high-severity vulnerability affecting Argo CD versions before 2.1.9 and 2.2.x before 2.2.4. This vulnerability allows directory traversal due to an error in helmTemplate in the repository.go file. Specifically, attackers may exploit this flaw to access sensitive information, such as credentials stored in YAML files. The CVSS score for this vulnerability is 7.7, indicating a high severity level, which necessitates immediate attention from organizations utilizing this software.
The impact of this vulnerability is significant, as it can lead to unauthorized access to sensitive data, posing a risk to organizations' security. The attack vector is network-based, and the complexity of the attack is low, with attackers requiring only low privileges and no user interaction. Given these factors, organizations should prioritize addressing this vulnerability in their patch management processes.
Currently, there are no public exploits confirmed for this vulnerability, but it is important to remain vigilant. Organizations must implement timely remediation measures to mitigate the risk of potential exploitation. It is crucial to stay informed about patch releases and updates related to Argo CD to ensure that systems remain secure.
Organizations should prioritize patching immediately to ensure that their deployments are secure and to protect against potential data breaches.
Vulnerability Details
Argo CD before 2.1.9 and 2.2.x before 2.2.4 allows directory traversal related to Helm charts because of an error in helmTemplate in repository.go. This issue is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')). The vulnerability was published on February 4, 2022, and is currently listed as modified.
The CVSS score of 7.7 reflects a high level of risk, with a confidentiality impact rated as high, indicating that sensitive information could be potentially exposed. Organizations using Argo CD should verify their version and implement patches as soon as possible.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of file paths in the helmTemplate function within the repository.go file. This flaw allows attackers to exploit the application and access files outside intended directories, thereby compromising the confidentiality of sensitive information.
The attack vector for this vulnerability is network-based, meaning attackers can exploit it remotely. The attack complexity is low, requiring minimal effort and low privileges to execute. There is no requirement for user interaction, which increases the risk of exploitation.
In terms of impact, the vulnerability affects confidentiality significantly, as sensitive data may be leaked. However, it does not impact integrity or availability, making it crucial to focus on preventing unauthorized access to confidential information.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive information, such as user credentials and configuration files. This vulnerability presents a significant threat, especially for organizations utilizing Argo CD in production environments. The potential blast radius is extensive, as compromised credentials may lead to further exploitation of systems and data breaches.
Organizations should address this vulnerability in their priority patch cycle, as the risk of exploitation is high, particularly in networked environments where attackers can exploit the vulnerability remotely. The urgency of remediation is underscored by the CVSS score of 7.7 and the fact that it allows access to sensitive data.

Affected Versions
The following versions of Argo CD are affected by this vulnerability: all versions prior to 2.1.9 and versions 2.2.x prior to 2.2.4. Organizations should ensure they are running the latest secure version of Argo CD to mitigate this risk.
Mitigation & Remediation
Organizations should upgrade to Argo CD version 2.1.9 or 2.2.4 or later to remediate this vulnerability. If an immediate upgrade is not feasible, consider implementing workarounds such as restricting access to sensitive files and monitoring for unauthorized access attempts as temporary measures.
Additionally, organizations should implement configuration hardening to ensure that sensitive files are not exposed and apply network controls to limit access to the Argo CD environment.
For comprehensive security validation, organizations may consider engaging in penetration testing to identify any additional vulnerabilities.
Detection Guidance
Organizations should monitor logs for unusual access patterns that may indicate an attempted exploitation of this vulnerability. Key indicators to observe include unexpected file access attempts and unauthorized attempts to read sensitive configuration files.
Behavioral anomalies within the system, such as unexpected changes to file permissions or access controls, should also be flagged for further investigation.
AppSecure Threat Intelligence Insight
