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"}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","baseScore":7.2,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.2,"impactScore":5.9},{"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:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-74"},{"lang":"en","value":"CWE-393"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:getgrav:grav:1.7.42:*:*:*:*:*:*:*","matchCriteriaId":"45FAF600-2018-4CD3-BDBD-FDB3AB736A64"},{"vulnerable":true,"criteria":"cpe:2.3:a:getgrav:grav:1.7.42.1:*:*:*:*:*:*:*","matchCriteriaId":"9F345F3C-7190-42C9-B8BF-5E822F6054BE"}]}]}],"references":[{"url":"https://github.com/getgrav/grav/commit/71bbed12f950de8335006d7f91112263d8504f1b","source":"security-advisories@github.com","tags":["Product"]},{"url":"https://github.com/getgrav/grav/commit/b4c62101a43051fc7f5349c7d0a5b6085375c1d7","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/getgrav/grav/security/advisories/GHSA-9436-3gmp-4f53","source":"security-advisories@github.com","tags":["Exploit","Mitigation","Vendor Advisory"]},{"url":"https://github.com/getgrav/grav/commit/71bbed12f950de8335006d7f91112263d8504f1b","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Product"]},{"url":"https://github.com/getgrav/grav/commit/b4c62101a43051fc7f5349c7d0a5b6085375c1d7","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://github.com/getgrav/grav/security/advisories/GHSA-9436-3gmp-4f53","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Exploit","Mitigation","Vendor Advisory"]}]}}]}
