https://notcve.org/view.php?id=CVE-2021-22926
libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport, an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file, it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users (like `/tmp`), a malicious user can create a file name with the same name as the app wants to use by name, and thereby trick the application to use the file based cert instead of the one referred to by name making libcurl send the wrong client certificate in the TLS connection handshake. Las aplicaciones que usan libcurl pueden pedir un certificado de cliente específico para ser usado en una transferencia. Esto se hace con la opción "CURLOPT_SSLCERT" ("--cert" con la herramienta de línea de comandos).Cuando libcurl se construye para usar la biblioteca TLS nativa de macOS Transporte Seguro, una aplicación puede pedir el certificado del cliente por su nombre o con un nombre de archivo - usando la misma opción. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1234760 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/rbf4ce74b0d1fa9810dec50ba3ace0caeea677af7c27a97111c06ccb7%40%3Cdev.kafka.apache.org%3E https://lists.apache.org/thread.html/rbf4ce74b0d1fa9810dec50ba3ace0caeea677af7c27a97111c06ccb7%40%3Cuser • CWE-295: Improper Certificate Validation CWE-840: Business Logic Errors •
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 •
CVSS: 5.3EPSS: 0%CPEs: 45EXPL: 1CVE-2021-22925 – curl: Incorrect fix for CVE-2021-22898 TELNET stack contents disclosure
https://notcve.org/view.php?id=CVE-2021-22925
curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing the string provided by the application. curl soporta la opción de línea de comandos "-t", conocida como "CURLOPT_TELNETOPTIONS" en libcurl. Debido a un fallo en el analizador de opciones para el envío de variables "NEW_ENV", libcurl podría pasar datos no inicializados de un búfer en la región stack de la memoria al servidor. Por lo tanto, podría revelar potencialmente información interna confidencial al servidor usando un protocolo de red de texto sin cifrar. • http://seclists.org/fulldisclosure/2021/Sep/39 http://seclists.org/fulldisclosure/2021/Sep/40 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://hackerone.com/reports/1223882 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FRUCW2UVNYUDZF72DQLFQR4PJEC6CF7V https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20210902-0003 https://support.apple& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-908: Use of Uninitialized Resource •
