CVSS: 4.3EPSS: 0%CPEs: 60EXPL: 1CVE-2021-22924 – curl: Bad connection reuse due to flawed path name checks
https://notcve.org/view.php?id=CVE-2021-22924
libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate. libcurl mantiene las conexiones usadas previamente en un pool de conexiones para reusarlas en posteriores transferencias, si una de ellas coincide con la configuración. Debido a errores en la lógica, la función de coincidencia de la configuración no tenía en cuenta "issuercert" y comparaba las rutas implicadas *sin tener en cuenta el caso*, que podía conllevar a que libcurl reusara conexiones erróneas. Las rutas de los archivos son, o pueden ser, casos confidenciales en muchos sistemas, pero no en todos, y pueden incluso variar dependiendo de los sistemas de archivos usados. La comparación tampoco incluía el "issuercert" que una transferencia puede ajustar para calificar cómo verificar el certificado del servidor A flaw was found in libcurl in the way libcurl handles previously used connections without accounting for 'issuer cert' and comparing the involved paths case-insensitively. This flaw allows libcurl to use the wrong connection. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-732250.pdf https://hackerone.com/reports/1223565 https://lists.apache.org/thread.html/r61db8e7dcb56dc000a5387a88f7a473bacec5ee01b9ff3f55308aacc%40%3Cdev.kafka.apache.org%3E https://lists.apache.org/thread.html/r61db8e7dcb56dc000a5387a88f7a473bacec5ee01b9ff3f55308aacc%40%3Cusers.kafka.apache.org%3E https://lists.apache.org/thread.html/rbf4ce74b0d1fa9810dec50ba3ace0c • CWE-20: Improper Input Validation CWE-295: Improper Certificate Validation CWE-706: Use of Incorrectly-Resolved Name or Reference •
