CVE-2021-22897
https://notcve.org/view.php?id=CVE-2021-22897
curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport security significantly. curl versiones 7.61.0 hasta 7.76.1, sufre de exposición de un elemento de datos a una sesión equivocada debido a un error en el código para la función CURLOPT_SSL_CIPHER_LIST cuando libcurl es construído para usar la biblioteca TLS de Schannel. El ajuste de cifrado seleccionado se almacenaba en una única variable "static" en la biblioteca, lo que tiene el sorprendente efecto secundario de que si una aplicación establece múltiples transferencias concurrentes, la última que ajusta los cifrados controlará accidentalmente el ajuste usado por todas las transferencias. En el peor de los casos, esto debilita significativamente la seguridad del transporte • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2021-22897.html https://github.com/curl/curl/commit/bbb71507b7bab52002f9b1e0880bed6a32834511 https://hackerone.com/reports/1172857 https://security.netapp.com/advisory/ntap-20210727-0007 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html • CWE-668: Exposure of Resource to Wrong Sphere CWE-840: Business Logic Errors •
