CVE-2022-23536 (GCVE-0-2022-23536)

Vulnerability from cvelistv5 – Published: 2022-12-19 21:10 – Updated: 2025-04-16 18:23

Summary
Cortex provides multi-tenant, long term storage for Prometheus. A local file inclusion vulnerability exists in Cortex versions 1.13.0, 1.13.1 and 1.14.0, where a malicious actor could remotely read local files as a result of parsing maliciously crafted Alertmanager configurations when submitted to the Alertmanager Set Configuration API. Only users of the Alertmanager service where `-experimental.alertmanager.enable-api` or `enable_api: true` is configured are affected. Affected Cortex users are advised to upgrade to patched versions 1.13.2 or 1.14.1. However as a workaround, Cortex administrators may reject Alertmanager configurations containing the `api_key_file` setting in the `opsgenie_configs` section before sending to the Set Alertmanager Configuration API.
Severity ?

Sin embargo, como workaround, los administradores de Cortex pueden rechazar las configuraciones de Alertmanager que contengan la configuraci\u00f3n `api_key_file` en la secci\u00f3n `opsgenie_configs` antes de enviarlas a la API Set Alertmanager Configuration.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N\",\"baseScore\":6.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"NONE\"},\"exploitabilityScore\":2.8,\"impactScore\":3.6},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N\",\"baseScore\":6.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"NONE\"},\"exploitabilityScore\":2.8,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-73\"},{\"lang\":\"en\",\"value\":\"CWE-184\"},{\"lang\":\"en\",\"value\":\"CWE-641\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"NVD-CWE-noinfo\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:linuxfoundation:cortex:1.13.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"99530D49-4F18-4E0C-81B3-543FFB1A9916\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:linuxfoundation:cortex:1.13.1:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"244198BF-FD25-44A5-814D-5E7C7B583D11\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:linuxfoundation:cortex:1.14.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"4F2FE6BB-9BF1-4620-ABEA-143828D3B0D4\"}]}]}],\"references\":[{\"url\":\"https://cortexmetrics.io/docs/api/#set-alertmanager-configuration\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://github.com/cortexproject/cortex/releases/tag/v1.13.2\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Release Notes\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/cortexproject/cortex/releases/tag/v1.14.1\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Release Notes\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/cortexproject/cortex/security/advisories/GHSA-cq2g-pw6q-hf7j\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Third Party Advisory\"]},{\"url\":\"https://cortexmetrics.io/docs/api/#set-alertmanager-configuration\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"https://github.com/cortexproject/cortex/releases/tag/v1.13.2\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Release Notes\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/cortexproject/cortex/releases/tag/v1.14.1\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Release Notes\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/cortexproject/cortex/security/advisories/GHSA-cq2g-pw6q-hf7j\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\"]}]}}",
