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 •
