A vulnerability in GitOps run could allow a local user or process to alter a Kubernetes cluster's resources. GitOps run has a local S3 bucket which it uses for synchronizing files that are later applied against a Kubernetes cluster. Its endpoint had no security controls to block unauthorized access, therefore allowing local users (and processes) on the same machine to see and alter the bucket content. By leveraging this vulnerability, an attacker could pick a workload of their choosing and inject it into the S3 bucket, which resulted in the successful deployment in the target cluster, without the need to provide any credentials to either the S3 bucket nor the target Kubernetes cluster. There are no known workarounds for this issue, please upgrade. This vulnerability has been fixed by commits 75268c4 and 966823b. Users should upgrade to Weave GitOps version >= v0.12.0 released on 08/12/2022. ### Workarounds There is no workaround for this vulnerability. ### References Disclosed by Paulo Gomes, Senior Software Engineer, Weaveworks. ### For more information If you have any questions or comments about this advisory: - Open an issue in [Weave GitOps repository](https://github.com/weaveworks/weave-gitops) - Email us at [support@weave.works](mailto:support@weave.works) ## CNA-Record (Kanon, cvelistV5) - CNA: **GitHub_M** - State: PUBLISHED - Stand: 2025-03-10 21:31:29 - CNA-CVSS: **8.9** (`CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`) ## CISA-Anreicherung (vulnrichment/ADP) - CISA-SSVC (Coordinator, v2.0.3): - Exploitation: **none** - Automatable: **no** - Technical Impact: **total** ## CVSS-Vektor ``` CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H ``` | Metrik | Wert | Bewertung | |---|---|---| | AV Angriffsvektor | Benachbart | warn | | AC Komplexität | Gering | bad | | PR Privilegien | Keine | bad | | UI Interaktion | Erforderlich | good | | S Scope | Verändert | bad | | C Vertraulichkeit | Hoch | bad | | I Integrität | Hoch | bad | | A Verfügbarkeit | Hoch | bad | ## Schwachstellen-Klasse - **CWE-284** — Improper Access Control The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. - **CWE-538** — Insertion of Sensitive Information into Externally-Accessible File or Directory The product places sensitive information into files or directories that are accessible to actors who are allowed to have access to the files, but not to the sensitive information. - **CWE-552** — Files or Directories Accessible to External Parties The product makes files or directories accessible to unauthorized actors, even though they should not be. ## Angriffsmuster (CAPEC) - [CAPEC-19 — Embedding Scripts within Scripts](https://capec.mitre.org/data/definitions/19.html) _(Severity: High)_ - [CAPEC-441 — Malicious Logic Insertion](https://capec.mitre.org/data/definitions/441.html) _(Severity: High)_ - [CAPEC-478 — Modification of Windows Service Configuration](https://capec.mitre.org/data/definitions/478.html) _(Severity: High)_ - [CAPEC-479 — Malicious Root Certificate](https://capec.mitre.org/data/definitions/479.html) _(Severity: Low)_ - [CAPEC-502 — Intent Spoof](https://capec.mitre.org/data/definitions/502.html) - [CAPEC-503 — WebView Exposure](https://capec.mitre.org/data/definitions/503.html) - [CAPEC-536 — Data Injected During Configuration](https://capec.mitre.org/data/definitions/536.html) _(Severity: High)_ - [CAPEC-546 — Incomplete Data Deletion in a Multi-Tenant Environment](https://capec.mitre.org/data/definitions/546.html) _(Severity: Medium)_ ## ATT&CK-Techniken - [T1027.009 — Obfuscated Files or Information: Embedded Payloads](https://attack.mitre.org/techniques/T1027/009/) - [T1546.004 — Event Triggered Execution:.bash_profile and .bashrc](https://attack.mitre.org/techniques/T1546/004/) - [T1546.016 — Event Triggered Execution: Installer Packages](https://attack.mitre.org/techniques/T1546/016/) - [T1574.011 — Hijack Execution Flow:Service Registry Permissions Weakness](https://attack.mitre.org/techniques/T1574/011/) - [T1543.003 — Create or Modify System Process:Windows Service](https://attack.mitre.org/techniques/T1543/003/) - [T1553.004 — Subvert Trust Controls:Install Root Certificate](https://attack.mitre.org/techniques/T1553/004/) ## Patch verfügbar (OSV) - eeb3a50c4b0bc98335fe3544e0c704b31377a52f (Commit) ## Referenzen - - - --- _Exportiert aus dem [tsecurity.de CVE-Dossier](https://tsecurity.de/sicherheitsluecken/cve-2022-23508/) · Datenquellen: EUVD (ENISA), NVD, OSV, CISA KEV, FIRST EPSS, Exploit-DB, BSI WID (CSAF)_
