rzodkiewka

Downloads CWE and CVE files, then simplify data and saves them as json files. cwe.json file has all the data, CVEs are splitted in files named after CWE. Library for sarenka app.

1. Downloads CWE xml file from https://cwe.mitre.org/data/xml/cwec_latest.xml.zip
2. Saves CWEs in .\output\cwe.json
3. Downloads CVE files from https://nvd.nist.gov/vuln/data-feeds#JSON_FEED (in table with id "divJSONFeeds")
4. Saves CVEs in .\output\cve.json
5. Split CVEs by CWE and saves in files .\cve_output\CWE-.json

Including the HttpOnly flag in the Set-Cookie HTTP response header helps mitigate the risk associated with Cross-Site Scripting (XSS) where an attacker's script code might attempt to read the contents of a cookie and exfiltrate information obtained. When set, browsers that support the flag will not reveal the contents of the cookie to a third party via client-side script executed via XSS."
