Grav is subject to a server side template injection (SSTI) vulnerability. The fix for another SSTI vulnerability using `|map`, `|filter` and `|reduce` twigs implemented in the commit `71bbed1` introduces bypass of the denylist due to incorrect return value from `isDangerousFunction()`, which allows to execute the payload prepending double backslash (`\\\\`). The `isDangerousFunction()` check in version 1.7.42 and onwards retuns `false` value instead of `true` when the `\\` symbol is found in the `$name`. This vulnerability can be exploited if the attacker has access to: 1. an Administrator account, or 2. a non-administrator, user account that has Admin panel access and Create/Update page permissions. A fix for this vulnerability has been introduced in commit `b4c6210` and is included in release version `1.7.42.2`. Users are advised to upgrade. There are no known workarounds for this vulnerability.\n\n"}], "source": {"advisory": "GHSA-9436-3gmp-4f53", "discovery": "UNKNOWN"}}, "adp": [{"providerMetadata": {"orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T17:23:27.730Z"}, "title": "CVE Program Container", "references": [{"name": "https://github.com/getgrav/grav/security/advisories/GHSA-9436-3gmp-4f53", "tags": ["x_refsource_CONFIRM", "x_transferred"], "url": "https://github.com/getgrav/grav/security/advisories/GHSA-9436-3gmp-4f53"}, {"name": "https://github.com/getgrav/grav/commit/71bbed12f950de8335006d7f91112263d8504f1b", "tags": ["x_refsource_MISC", "x_transferred"], "url": "https://github.com/getgrav/grav/commit/71bbed12f950de8335006d7f91112263d8504f1b"}, {"name": "https://github.com/getgrav/grav/commit/b4c62101a43051fc7f5349c7d0a5b6085375c1d7", "tags": ["x_refsource_MISC", "x_transferred"], "url": "https://github.com/getgrav/grav/commit/b4c62101a43051fc7f5349c7d0a5b6085375c1d7"}]}, {"affected": [{"vendor": "getgrav", "product": "grav", "cpes": ["cpe:2.3:a:getgrav:grav:*:*:*:*:*:*:*:*"], "defaultStatus": "unknown", "versions": [{"version": "0", "status": "affected", "lessThan": "1.7.42.2", "versionType": "custom"}]}], "metrics": [{"other": {"type": "ssvc", "content": {"timestamp": "2024-10-18T16:06:14.894046Z", "id": "CVE-2023-37897", "options": [{"Exploitation": "poc"}, {"Automatable": "no"}, {"Technical Impact": "total"}], "role": "CISA Coordinator", "version": "2.0.3"}}}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-10-18T17:19:07.910Z"}}]}}
