Using a specially-crafted repository, Git prior to versions 2.39.2, 2.38.4, 2.37.6, 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8 can be tricked into using its local clone optimization even when using a non-local transport. Though Git will abort local clones whose source `$GIT_DIR/objects` directory contains symbolic links, the `objects` directory itself may still be a symbolic link. These two may be combined to include arbitrary files based on known paths on the victim's filesystem within the malicious repository's working copy, allowing for data exfiltration in a similar manner as CVE-2022-39253. A fix has been prepared and will appear in v2.39.2 v2.38.4 v2.37.6 v2.36.5 v2.35.7 v2.34.7 v2.33.7 v2.32.6, v2.31.7 and v2.30.8. If upgrading is impractical, two short-term workarounds are available. Avoid cloning repositories from untrusted sources with `--recurse-submodules`. Instead, consider cloning repositories without recursively cloning their submodules, and instead run `git submodule update` at each layer. Before doing so, inspect each new `.gitmodules` file to ensure that it does not contain suspicious module URLs."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-59"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2023-22490", "ASSIGNER": "security-advisories@github.com"}}, "impact": {"baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 5.5, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N", "integrityImpact": "NONE", "userInteraction": "REQUIRED", "attackComplexity": "LOW", "availabilityImpact": "NONE", "privilegesRequired": "NONE", "confidentialityImpact": "HIGH"}, "impactScore": 3.6, "exploitabilityScore": 1.8}}, "publishedDate": "2023-02-14T20:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.39.2", "versionStartIncluding": "2.39.0"}, {"cpe23Uri": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.38.4", "versionStartIncluding": "2.38.0"}, {"cpe23Uri": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.37.6", "versionStartIncluding": "2.37.0"}, {"cpe23Uri": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.36.5", "versionStartIncluding": "2.36.0"}, {"cpe23Uri": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.35.7", "versionStartIncluding": "2.35.0"}, {"cpe23Uri": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.34.7", "versionStartIncluding": "2.34.0"}, {"cpe23Uri": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.33.7", "versionStartIncluding": "2.33.0"}, {"cpe23Uri": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.32.6", "versionStartIncluding": "2.32.0"}, {"cpe23Uri": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.31.7", "versionStartIncluding": "2.31.0"}, {"cpe23Uri": "cpe:2.3:a:git-scm:git:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.30.8"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2023-02-23T22:24Z"}
