{"id":"AZL-6361","summary":"CVE-2021-22922 affecting package curl for versions less than 7.76.0-5","details":"When curl is instructed to download content using the metalink feature, thecontents is verified against a hash provided in the metalink XML file.The metalink XML file points out to the client how to get the same contentfrom a set of different URLs, potentially hosted by different servers and theclient can then download the file from one or several of them. In a serial orparallel manner.If one of the servers hosting the contents has been breached and the contentsof the specific file on that server is replaced with a modified payload, curlshould detect this when the hash of the file mismatches after a completeddownload. It should remove the contents and instead try getting the contentsfrom another URL. This is not done, and instead such a hash mismatch is onlymentioned in text and the potentially malicious content is kept in the file ondisk.","modified":"2026-04-01T05:20:11.188449Z","published":"2021-08-05T21:15:11Z","upstream":["CVE-2021-22922"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-22922"}],"affected":[{"package":{"name":"curl","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/curl"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.76.0-5"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-6361.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N"}]}
