An improper error handling in HTTPS requests management in WP-CLI version 0.12.0 and later allows remote attackers able to intercept the communication to remotely disable the certificate verification on WP-CLI side, gaining full control over the communication content, including the ability to impersonate update servers and push malicious updates towards WordPress instances controlled by the vulnerable WP-CLI agent, or push malicious updates toward WP-CLI itself. The vulnerability stems from the fact that the default behavior of `WP_CLI\\Utils\\http_request()` when encountering a TLS handshake error is to disable certificate validation and retry the same request. The default behavior has been changed with version 2.5.0 of WP-CLI and the `wp-cli/wp-cli` framework (via https://github.com/wp-cli/wp-cli/pull/5523) so that the `WP_CLI\\Utils\\http_request()` method accepts an `$insecure` option that is `false` by default and consequently that a TLS handshake failure is a hard error by default. This new default is a breaking change and ripples through to all consumers of `WP_CLI\\Utils\\http_request()`, including those in separate WP-CLI bundled or third-party packages. https://github.com/wp-cli/wp-cli/pull/5523 has also added an `--insecure` flag to the `cli update` command to counter this breaking change. There is no direct workaround for the default insecure behavior of `wp-cli/wp-cli` versions before 2.5.0. The workaround for dealing with the breaking change in the commands directly affected by the new secure default behavior is to add the `--insecure` flag to manually opt-in to the previous insecure behavior." } ], "metrics": [ { "cvssV3_1": { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 9.1, "baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N", "version": "3.1" } } ], "problemTypes": [ { "descriptions": [ { "cweId": "CWE-295", "description": "CWE-295: Improper Certificate Validation", "lang": "en", "type": "CWE" } ] } ], "providerMetadata": { "dateUpdated": "2021-06-07T20:50:17", "orgId": "a0819718-46f1-4df5-94e2-005712e83aaa", "shortName": "GitHub_M" }, "references": [ { "tags": [ "x_refsource_CONFIRM" ], "url": "https://github.com/wp-cli/wp-cli/security/advisories/GHSA-rwgm-f83r-v3qj" }, { "tags": [ "x_refsource_MISC" ], "url": "https://github.com/wp-cli/checksum-command/pull/86" }, { "tags": [ "x_refsource_MISC" ], "url": "https://github.com/wp-cli/config-command/pull/128" }, { "tags": [ "x_refsource_MISC" ], "url": "https://github.com/wp-cli/core-command/pull/186" }, { "tags": [ "x_refsource_MISC" ], "url": "https://github.com/wp-cli/extension-command/pull/287" }, { "tags": [ "x_refsource_MISC" ], "url": "https://github.com/wp-cli/package-command/pull/138" }, { "tags": [ "x_refsource_MISC" ], "url": "https://github.com/wp-cli/wp-cli/pull/5523" } ], "source": { "advisory": "GHSA-rwgm-f83r-v3qj", "discovery": "UNKNOWN" }, "title": "Improper Certificate Validation in WP-CLI framework", "x_legacyV4Record": { "CVE_data_meta": { "ASSIGNER": "security-advisories@github.com", "ID": "CVE-2021-29504", "STATE": "PUBLIC", "TITLE": "Improper Certificate Validation in WP-CLI framework" }, "affects": { "vendor": { "vendor_data": [ { "product": { "product_data": [ { "product_name": "wp-cli", "version": { "version_data": [ { "version_value": "< 2.5.0" } ] } } ] }, "vendor_name": "wp-cli" } ] } }, "data_format": "MITRE", "data_type": "CVE", "data_version": "4.0", "description": { "description_data": [ { "lang": "eng", "value": "WP-CLI is the command-line interface for WordPress.
