- Summary
- CVE-2022-27780 affecting package curl for versions less than 7.83.1-1
- Details
-
The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a different URL usingthe wrong host name when it is later retrieved.For example, a URL like
http://example.com%2F127.0.0.1/, would be allowed bythe parser and get transposed intohttp://example.com/127.0.0.1/. This flawcan be used to circumvent filters, checks and more. - References
