By crafting malicious XML content that exploits inefficient regular expression complexity used in the parsing process, an attacker can cause a denial-of-service (DoS) condition. This vulnerability allows for the system to hang and consume significant resources, potentially rendering services that utilize Scrapy for XML processing unresponsive." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-1333 Inefficient Regular Expression Complexity", "cweId": "CWE-1333" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "scrapy", "product": { "product_data": [ { "product_name": "scrapy/scrapy", "version": { "version_data": [ { "version_affected": "<", "version_name": "unspecified", "version_value": "2.11" } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://huntr.com/bounties/271f94f2-1e05-4616-ac43-41752389e26b", "refsource": "MISC", "name": "https://huntr.com/bounties/271f94f2-1e05-4616-ac43-41752389e26b" }, { "url": "https://github.com/scrapy/scrapy/commit/479619b340f197a8f24c5db45bc068fb8755f2c5", "refsource": "MISC", "name": "https://github.com/scrapy/scrapy/commit/479619b340f197a8f24c5db45bc068fb8755f2c5" } ] }, "source": { "advisory": "271f94f2-1e05-4616-ac43-41752389e26b", "discovery": "EXTERNAL" }, "impact": { "cvss": [ { "version": "3.0", "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "baseScore": 7.5, "baseSeverity": "HIGH" } ] } }
