CVE-2022-24904
Symlink following allows leaking out-of-bound manifests and JSON files from Argo CD repo-server
In short
Argo CD's repo-server improperly follows symlinks in Git repositories, allowing a user with write access to steal sensitive files like manifests or secrets from the server. This could expose confidential configuration data or decrypted files from other applications.
Technical detail
A symlink following vulnerability (CWE-59, CWE-61) in Argo CD repo-server versions 0.7.0 through 2.3.3 permits an authenticated user with repository write permissions to read out-of-bounds files by committing symlinks within directory-type Applications. Attack surface includes manifest files and JSON-formatted mounted secrets; exploitation requires pre-existing repo access and vulnerable Application configuration.
Summary generated and translated by AI from the official description.
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD starting with version 0.7.0 and prior to versions 2.1.15m 2.2.9, and 2.3.4 is vulnerable to a symlink following bug allowing a malicious user with repository write access to leak sensitive files from Argo CD's repo-server. A malicious Argo CD user with write access for a repository which is (or may be) used in a directory-type Application may commit a symlink which points to an out-of-bounds file. Sensitive files which could be leaked include manifest files from other Applications' source repositories (potentially decrypted files, if you are using a decryption plugin) or any JSON-formatted secrets which have been mounted as files on the repo-server. A patch for this vulnerability has been released in Argo CD versions 2.3.4, 2.2.9, and 2.1.15. Users of versions 2.3.0 or above who do not have any Jsonnet/directory-type Applications may disable the Jsonnet/directory config management tool as a workaround.
