{"id":"GHSA-g687-f2gx-6wm8","summary":"Argo CD repo-server  Denial of Service vulnerability","details":"### Impact\nAll versions of ArgoCD starting from v2.4 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector. Specifically, the said component extracts a user-controlled tar.gz file without validating the size of its inner files. As a result, a malicious, low-privileged user can send a malicious tar.gz file that exploits this vulnerability to the repo-server, thereby harming the system's functionality and availability. Additionally, the repo-server is susceptible to another vulnerability due to the fact that it does not check the extracted file permissions before attempting to delete them. Consequently, an attacker can craft a malicious tar.gz archive in a way that prevents the deletion of its inner files when the manifest generation process is completed.\n\n\n### Patches\nA patch for this vulnerability has been released in the following Argo CD versions:\n\n* v2.6.15\n* v2.7.14\n* v2.8.3\n\n### Workarounds\nThe only way to completely resolve the issue is to upgrade.\n\n#### Mitigations\nConfigure RBAC (Role-Based Access Control) and provide access for configuring applications only to a limited number of administrators. These administrators should utilize trusted and verified Helm charts.\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [the Argo CD issue tracker](https://github.com/argoproj/argo-cd/issues) or [discussions](https://github.com/argoproj/argo-cd/discussions)\n* Join us on [Slack](https://argoproj.github.io/community/join-slack) in channel #argo-cd\n\n### Credits\nThis vulnerability was found & reported by GE Vernova – Amit Laish.\n\nThe Argo team would like to thank these contributors for their responsible disclosure and constructive communications during the resolve of this issue\n","aliases":["BIT-argo-cd-2023-40584","CVE-2023-40584","GO-2023-2050"],"modified":"2024-08-21T14:41:54.467121Z","published":"2023-09-11T12:59:48Z","database_specific":{"cwe_ids":["CWE-400"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2023-09-11T12:59:48Z","nvd_published_at":"2023-09-07T23:15:10Z"},"references":[{"type":"WEB","url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-g687-f2gx-6wm8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-40584"},{"type":"WEB","url":"https://github.com/argoproj/argo-cd/commit/1391ba72149655e4884d357586d3201f15bc92dc"},{"type":"WEB","url":"https://github.com/argoproj/argo-cd/commit/b8f92c4ff226346624f43de3f25d81dac6386674"},{"type":"PACKAGE","url":"https://github.com/argoproj/argo-cd"},{"type":"WEB","url":"https://github.com/argoproj/argo-cd/releases/tag/v2.6.15"},{"type":"WEB","url":"https://github.com/argoproj/argo-cd/releases/tag/v2.7.14"},{"type":"WEB","url":"https://github.com/argoproj/argo-cd/releases/tag/v2.8.3"}],"affected":[{"package":{"name":"github.com/argoproj/argo-cd/v2","ecosystem":"Go","purl":"pkg:golang/github.com/argoproj/argo-cd/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.4.0"},{"fixed":"2.6.15"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/09/GHSA-g687-f2gx-6wm8/GHSA-g687-f2gx-6wm8.json"}},{"package":{"name":"github.com/argoproj/argo-cd/v2","ecosystem":"Go","purl":"pkg:golang/github.com/argoproj/argo-cd/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.7.0"},{"fixed":"2.7.14"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/09/GHSA-g687-f2gx-6wm8/GHSA-g687-f2gx-6wm8.json"}},{"package":{"name":"github.com/argoproj/argo-cd/v2","ecosystem":"Go","purl":"pkg:golang/github.com/argoproj/argo-cd/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.8.0"},{"fixed":"2.8.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/09/GHSA-g687-f2gx-6wm8/GHSA-g687-f2gx-6wm8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
