Prior to 1.1.1, the terragrunt catalog command derives a predictable per-repository catalog clone root under the shared system temporary directory and follows a symlink already placed at that path. A local attacker who can write to the temporary directory and predict the cataloged repository can redirect cleanup and cloning outside the intended root, causing an existing repository-named directory to be deleted and replaced in the victim's security context. The attack requires the victim to run terragrunt catalog on a shared host while the symlink is present, and it is not remotely exploitable. This issue is fixed in version 1.1.1."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"gruntwork-io","product":"terragrunt","versions":[{"version":"< 1.1.1","status":"affected"}]}]}],"metrics":{"cvssMetricV40":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"4.0","vectorString":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","baseScore":4.4,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","attackRequirements":"PRESENT","privilegesRequired":"LOW","userInteraction":"PASSIVE","vulnConfidentialityImpact":"NONE","vulnIntegrityImpact":"HIGH","vulnAvailabilityImpact":"HIGH","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-59"},{"lang":"en","value":"CWE-377"}]}],"references":[{"url":"https://github.com/gruntwork-io/terragrunt/commit/668891c5a2ad2996f134bb8b00098754674ea94a","source":"security-advisories@github.com"},{"url":"https://github.com/gruntwork-io/terragrunt/pull/6438","source":"security-advisories@github.com"},{"url":"https://github.com/gruntwork-io/terragrunt/releases/tag/v1.1.1","source":"security-advisories@github.com"},{"url":"https://github.com/gruntwork-io/terragrunt/security/advisories/GHSA-wv6g-x823-wx9m","source":"security-advisories@github.com"}]}
