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"}}]}}
