漏洞描述
中文描述:
HAXX Haxx libcurl是瑞典HAXX公司的一个免费、开源的客户端URL传输库。该库支持FTP、FTPS、TFTP、HTTP等。 HAXX libcurl存在信息泄露漏洞,该漏洞源于libcurl可以将未初始化的数据从基于堆栈的缓冲区传递到服务器导致使用明文网络协议将敏感的内部信息泄露给服务。
英文描述:
curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol.
