CVE-2022-24731

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD starting with version 1.5.0 but before versions 2.1.11, 2.2.6, and 2.3.0 is vulnerable to a path traversal vulnerability, allowing a malicious user with read/write access to leak sensitive files from Argo CD’s repo-server. A malicious Argo CD user who has been granted `create` or `update` access to Applications can leak the contents of any text file on the repo-server. By crafting a malicious Helm chart and using it in an Application, the attacker can retrieve the sensitive file’s contents either as part of the generated manifests or in an error message. The attacker would have to know or guess the location of the target file. Sensitive files which could be leaked include files from another Application’s source repositories or any secrets which have been mounted as files on the repo-server. This vulnerability is patched in Argo CD versions 2.1.11, 2.2.6, and 2.3.0. The problem can be mitigated by avoiding storing secrets in git, avoiding mounting secrets as files on the repo-server, avoiding decrypting secrets into files on the repo-server, and carefully limiting who can `create` or `update` Applications.

CVE-2022-24757

The Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web applications. Prior to version 1.15.4, unauthorized actors can access sensitive information from server logs. Anytime a 5xx error is triggered, the auth cookie and other header values are recorded in Jupyter Server logs by default. Considering these logs do not require root access, an attacker can monitor these logs, steal sensitive auth/cookie information, and gain access to the Jupyter server. Jupyter Server version 1.15.4 contains a patch for this issue. There are currently no known workarounds.

CVE-2022-24730

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD starting with version 1.3.0 but before versions 2.1.11, 2.2.6, and 2.3.0 is vulnerable to a path traversal bug, compounded by an improper access control bug, allowing a malicious user with read-only repository access to leak sensitive files from Argo CD’s repo-server. A malicious Argo CD user who has been granted `get` access for a repository containing a Helm chart can craft an API request to the `/api/v1/repositories/{repo_url}/appdetails` endpoint to leak the contents of out-of-bounds files from the repo-server. The malicious payload would reference an out-of-bounds file, and the contents of that file would be returned as part of the response. Contents from a non-YAML file may be returned as part of an error message. The attacker would have to know or guess the location of the target file. Sensitive files which could be leaked include files from other Applications’ source repositories or any secrets which have been mounted as files on the repo-server. This vulnerability is patched in Argo CD versions 2.1.11, 2.2.6, and 2.3.0. The patches prevent path traversal and limit access to users who either A) have been granted Application `create` privileges or B) have been granted Application `get` privileges and are requesting details for a `repo_url` that has already been used for the given Application. There are currently no known workarounds.
