In versions 1.0 through 2.0b4, cpdb-libs is vulnerable to buffer overflows via improper use of `scanf(3)`. cpdb-libs uses the `fscanf()` and `scanf()` functions to parse command lines and configuration files, dropping the read string components into fixed-length buffers, but does not limit the length of the strings to be read by `fscanf()` and `scanf()` causing buffer overflows when a string is longer than 1023 characters. A patch for this issue is available at commit f181bd1f14757c2ae0f17cc76dc20421a40f30b7. As all buffers have a length of 1024 characters, the patch limits the maximum string length to be read to 1023 by replacing all occurrences of `%s` with `%1023s` in all calls of the `fscanf()` and `scanf()` functions." } ], "metrics": { "cvssMetricV31": [ { "source": "security-advisories@github.com", "type": "Secondary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 9.8, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH" }, "exploitabilityScore": 3.9, "impactScore": 5.9 }, { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 9.8, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH" }, "exploitabilityScore": 3.9, "impactScore": 5.9 } ] }, "weaknesses": [ { "source": "security-advisories@github.com", "type": "Secondary", "description": [ { "lang": "en", "value": "CWE-121" } ] } ], "configurations": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:a:openprinting:cpdb-libs:*:*:*:*:*:*:*:*", "versionStartIncluding": "1.0", "versionEndExcluding": "2.0", "matchCriteriaId": "57F84EB4-6BF2-4AAA-9BC6-F881F046A97B" }, { "vulnerable": true, "criteria": "cpe:2.3:a:openprinting:cpdb-libs:2.0:beta1:*:*:*:*:*:*", "matchCriteriaId": "367C92BD-4CA9-4024-B9FA-7430236C9F6F" }, { "vulnerable": true, "criteria": "cpe:2.3:a:openprinting:cpdb-libs:2.0:beta2:*:*:*:*:*:*", "matchCriteriaId": "CED72D06-A6D2-486F-B3FA-6ADA82262C6B" }, { "vulnerable": true, "criteria": "cpe:2.3:a:openprinting:cpdb-libs:2.0:beta3:*:*:*:*:*:*", "matchCriteriaId": "8545935C-24E9-49F6-8EBE-4D49F2C72F81" }, { "vulnerable": true, "criteria": "cpe:2.3:a:openprinting:cpdb-libs:2.0:beta4:*:*:*:*:*:*", "matchCriteriaId": "F7330E46-2ACD-4832-89F9-D0372C9BFF06" } ] } ] } ], "references": [ { "url": "http://www.openwall.com/lists/oss-security/2023/06/14/7", "source": "security-advisories@github.com", "tags": [ "Exploit", "Mailing List", "Third Party Advisory" ] }, { "url": "https://github.com/OpenPrinting/cpdb-libs/blob/85555fba64d34f53a2fce099b0488904cc48ed35/cpdb/cpdb-frontend.c#L372", "source": "security-advisories@github.com", "tags": [ "Product" ] }, { "url": "https://github.com/OpenPrinting/cpdb-libs/blob/85555fba64d34f53a2fce099b0488904cc48ed35/tools/cpdb-text-frontend.c#L362", "source": "security-advisories@github.com", "tags": [ "Product" ] }, { "url": "https://github.com/OpenPrinting/cpdb-libs/blob/85555fba64d34f53a2fce099b0488904cc48ed35/tools/cpdb-text-frontend.c#L453", "source": "security-advisories@github.com", "tags": [ "Product" ] }, { "url": "https://github.com/OpenPrinting/cpdb-libs/commit/f181bd1f14757c2ae0f17cc76dc20421a40f30b7", "source": "security-advisories@github.com", "tags": [ "Patch" ] }, { "url": "https://github.com/OpenPrinting/cpdb-libs/security/advisories/GHSA-25j7-9gfc-f46x", "source": "security-advisories@github.com", "tags": [ "Exploit", "Vendor Advisory" ] }, { "url": "http://www.openwall.com/lists/oss-security/2023/06/14/7", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Exploit", "Mailing List", "Third Party Advisory" ] }, { "url": "https://github.com/OpenPrinting/cpdb-libs/blob/85555fba64d34f53a2fce099b0488904cc48ed35/cpdb/cpdb-frontend.c#L372", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Product" ] }, { "url": "https://github.com/OpenPrinting/cpdb-libs/blob/85555fba64d34f53a2fce099b0488904cc48ed35/tools/cpdb-text-frontend.c#L362", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Product" ] }, { "url": "https://github.com/OpenPrinting/cpdb-libs/blob/85555fba64d34f53a2fce099b0488904cc48ed35/tools/cpdb-text-frontend.c#L453", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Product" ] }, { "url": "https://github.com/OpenPrinting/cpdb-libs/commit/f181bd1f14757c2ae0f17cc76dc20421a40f30b7", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Patch" ] }, { "url": "https://github.com/OpenPrinting/cpdb-libs/security/advisories/GHSA-25j7-9gfc-f46x", "source": "af854a3a-2127-422b-91ae-364da2661108", "tags": [ "Exploit", "Vendor Advisory" ] } ] }
