User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of IFF files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process.", "published": "2021-01-12T00:00:00", "modified": "2021-01-12T00:00:00", "cvss": {"score": 6.8, "vector": "AV:N/AC:M/Au:N/C:P/I:P/A:P"}, "cvss2": {"acInsufInfo": false, "cvssV2": {"accessComplexity": "MEDIUM", "accessVector": "NETWORK", "authentication": "NONE", "availabilityImpact": "PARTIAL", "baseScore": 6.8, "confidentialityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "vectorString": "AV:N/AC:M/Au:N/C:P/I:P/A:P", "version": "2.0"}, "exploitabilityScore": 8.6, "impactScore": 6.4, "obtainAllPrivilege": false, "obtainOtherPrivilege": false, "obtainUserPrivilege": false, "severity": "MEDIUM", "userInteractionRequired": true}, "cvss3": {"cvssV3": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 8.8, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version": "3.1"}, "exploitabilityScore": 2.8, "impactScore": 5.9}, "href": "https://www.zerodayinitiative.com/advisories/ZDI-21-005/", "reporter": "Francis Provencher {PRL}", "references": [], "cvelist": ["CVE-2021-21457"], "immutableFields": [], "lastseen": "2022-02-10T00:00:00", "viewCount": 12, "enchantments": {"dependencies": {"references": [{"type": "cve", "idList": ["CVE-2021-21457"]}], "rev": 4}, "score": {"value": 5.1, "vector": "NONE"}, "backreferences": {"references": [{"type": "cve", "idList": ["CVE-2021-21457"]}, {"type": "talos", "idList": ["SAP"]}]}, "exploitation": null, "epss": [{"cve": "CVE-2021-21457", "epss": "0.002100000", "percentile": "0.571740000", "modified": "2023-03-17"}], "vulnersScore": 5.1}, "_state": {"dependencies": 1645817337, "score": 1659842276, "epss": 1679062491}, "_internal": {"score_hash": "ea6875538d211111328792ac5e7505cb"}}
